IRSA announces the release of the Cluster Lensing And Supernova survey with Hubble (CLASH) Spitzer data and the Herschel Oxygen Project (HOP) Herschel Open Time Key Program.
CLASH is an HST Multi-Cycle Treasury program to survey 25 massive galaxy clusters at 16 wavelengths spanning from the near-UV to the near-IR. A series of programs with Spitzer have covered all CLASH galaxy clusters with IRAC Channels 1 and 2 (3.6 and 4.5 micron). Several of the targets include Channels 3 and 4 (5.8 and 8 micron) data. Spitzer mosaics, catalogs, and PSF images are now available.
HOP used HIFI to probe a range of molecular cloud environments to detect molecular oxygen. The three strongest transitions in the range covered by HIFI from energy levels lower than 120 K above the ground state were selected (487.3 GHz, 773.8 GHz and 1120.7 GHz) for the following targets: Sgr A, Sgr B2(S), OMC-1(Peak 1), Orion Bar, rho Oph A, NGC 1333 IRAS 4A, NGC 6334I and AFGL 2591. Both single LOs and Spectral scans are available. This program also provides a spectral map of rhoOph.
IRSA announces the PACS Evolutionary Probe (PEP) data release.
PEP is a Herschel guaranteed time deep extragalactic survey targeting six among the most popular "blank fields", ten lensing clusters of galaxies, and two z ~1 clusters at wavelengths of 100 and 160 microns. PEP also includes SPIRE observations of the two z ~1 clusters at wavelengths of 250, 350, and 500 microns. PEP data products include image maps, source catalogs, residual maps, and PSFs.
IRSA announces the release of new data products from the KINGFISH and S4G programs.
The Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel (KINGFISH) open time key program is an imaging and spectroscopic survey of 61 nearby (d<30 Mpc) galaxies, chosen to cover a wide range of galaxy properties and local interstellar medium (ISM) environments found in the nearby universe. Its broad goals are to characterize the ISM of present-day galaxies, the heating and cooling of their gaseous and dust components, and to better understand the physical processes linking star formation and the ISM. Herschel PACS and SPIRE images of the KINGFISH sample are now available.
The Spitzer Survey of Stellar Structure in Galaxies (S4G) exploration science program consists of a sample of 2,352 nearby galaxies, which have been mapped with IRAC channels 1 and 2 (3.6 and 4.5 microns). Galfit models are now available for all galaxies in S4G.
A new version of the Spitzer Heritage Archive user interface is now available, featuring:
- Access to new versions of the Spitzer Enhanced Imaging Products, and the ability to plot SEDs of objects in the Source List.
- Improved ability to create XY plots of quantities derived from catalog columns.
- Precovery of archival observations of moving objects.
IRSA announces the release of new data products from the Spitzer Enhanced Imaging Products, SPT-Spitzer Deep Field, and Spitzer Infrared Nearby Galaxies Survey programs.
The Spitzer Enhanced Imaging Products include Super Mosaics (combining data from multiple programs where appropriate) and a Source List of photometry for compact sources. The primary requirement on the Source List is very high reliability -- with areal coverage, completeness, and limiting depth being secondary considerations. The SEIP include data from the four channels of IRAC (3.6, 4.5, 5.8, 8 microns) and the 24 micron channel of MIPS. The Source List includes 42 million sources. Coverage tables for IRAC and MIPS are also available, as is a Traceback table to identify which AORs were used in each Super Mosaic.
The Spitzer-South Pole Telescope Deep Field (SSDF) is a wide-area survey using IRAC to cover 94 square degrees of extragalactic sky, making it the largest IRAC survey completed to date outside the Milky Way midplane. The SSDF is centered at 23:30,-55:00, in a region that combines observations spanning a broad wavelength range from numerous facilities. These include millimeter imaging from the South Pole Telescope, far-infrared observations from Herschel/SPIRE, X-ray observations from the XMM XXL survey, near-infrared observations from the VISTA Hemisphere Survey, and radio-wavelength imaging from the Australia Telescope Compact Array, in a panchromatic project designed to address major outstanding questions surrounding galaxy clusters and the baryon budget.
Updated optical spectra are now available for galaxies in SINGS, including enhanced previews and visualizations of the different extraction apertures.
IRSA and the U.S. Planck Data Center announce an update to the NASA Planck Archive. The following products are now available: 1. New maps for the cosmic microwave background from the SEVEM and Commander-Ruler component separation techniques; 2. An extensive set of simulations for foregrounds and the CMB; 3. Foreground masks which are used for the cosmological results discussed in the initial Planck project science papers. 4. Supplementary information on the SZ clusters from DR1; 5. An updated map of the Galactic dust emission. Complete information about the Planck DR1 December update is available.
The Wide-field Infrared Survey Explorer (WISE) and IRSA announce the AllWISE Data Release.
The AllWISE program combines data from WISE cryogenic and NEOWISE post-cryogenic survey phases, to form the most comprehensive view of the mid-infrared sky currently available. By combining the data from two complete sky coverage epochs in an advanced data processing system, AllWISE has generated new products that have enhanced photometric sensitivity and accuracy, and improved astrometric precision compared with the earlier WISE All-Sky Data Release. Exploiting the 6 month baseline between the WISE sky coverage epochs enables AllWISE to measure source motions for the first time, and to compute improved flux variability statistics.
AllWISE data release products include: a Source Catalog that contains 4-band fluxes, positions, apparent motion measurements, and flux variability statistics for over 747 million objects detected at SNR>5 in the combined exposures; a Multiepoch Photometry Database containing over 42 billion time-tagged, single-exposure fluxes for each object detected on the combined exposures; and an Image Atlas of 18,240 4-band calibrated FITS images, depth-of-coverage and noise maps that cover the sky produced by coadding nearly 7.9 million single-exposure images from the cryogenic and post-cryogenic survey phases.
A quick guide to the AllWISE data release, data access instructions and supporting documentation is available. A summary of the WISE mission resources is available on the WISE mission page.
IRSA announces the release of image and catalog data from the HERITAGE Herschel Open Time Key Program. The HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) Open Time Key Program mapped the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) at 100, 160, 250, 350, and 500 microns using the PACS and SPIRE instruments on ESA's Herschel Space Observatory. The overriding science goal of HERITAGE is to study the life cycle of matter as traced by dust in the LMC and SMC. There are two main pointings, one for the LMC and the other for the SMC. For each of these, the PACS and SPIRE pointings are slightly offset. Images and uncertainty maps in MJy/sr are available for all the bands. Coverage maps (in frames per pixel) are available for the SPIRE bands.
IRSA has released a new version of its Dust Extinction Service. This service gives the Galactic dust reddening for a line of sight, returning a reddening map, the corresponding 100 micron intensity, and the dust temperature, along with statistics for each. In Single Location mode, extinctions at multiple wavelengths are estimated. Improvements over the previous version include newer reddening values from Schlafly & Finkbeiner (2011) in addition to those of Schlegel et al. (1998); and the addition of the Spitzer IRAC filters and the two shorter wavelength WISE bands.
IRSA announces a recent update to its Herschel Data Search tool. This is a web interface that allows users to find data in the Herschel Science Archive maintained by ESA at the European Space Astronomy Centre (ESAC). Besides the standard positional queries per Instrument, the user will be able to search the archive selecting Observing Modes, Proposer and Proposal ID. The tool now supports "All Sky" and multiple-position searches as well.
IRSA announces the release of new images and a catalog from the Auriga-California Molecular Cloud Herschel program and new catalogs from the GLIMPSE360 Spitzer Exploration Science Program.
The Auriga-California Molecular Cloud program observed a 14.5 square degree area of the cloud in five far-infrared bands with ESA's Herschel Space Observatory. The data data include PACS (70 and 160 micron) and SPIRE (250, 350, and 500 micron) imaging for the East, Center, and West regions of the cloud, along with a source catalog.
The final release of GLIMPSE360 catalogs now covers the full area of the program, l=65-265 degrees, excluding l=102-109 and l=76-82 degrees.
IRSA announces the release of three new software tools: HIRES, Table Validator, and the IRSA Viewer.
HIRES is a web-based tool that allows users to produce higher spatial resolution images from archival data of the Infrared Astronomical Satellite (IRAS). HIRES can be a useful tool for studying morphology and for separating confused sources. It can produce spatial resolutions of better than an arcminute, roughly a five-fold increase over the unenhanced resolution.
Table Validator is a web-based tool that 1) checks whether an uploaded table is in IPAC Table Format, 2) checks whether it satisfies some additional restrictions imposed by IRSA's Catalog Search tool, and 3), if requested, tries to reformat the table to IPAC Table Format. The new version more accurately flags tables that do not meet the requirements of IRSA tools, and provides users with clearer descriptions of the incompatibilities found.
The IRSA Viewer is a new image/catalog preview interface that is based on the same image/catalog interface underlying the SHA. It provides enhanced previewing of images retrieved through a basic IRSA image search. It includes new features that will be added to the SHA in a future release, including new zoom options, and DS9 region file support.
IRSA announces the release of data from the SERVS Spitzer Exploration Science program, and the BOLOCAM v2.1 catalog.
The Spitzer Extragalactic Representative Volume Survey" (SERVS) imaged five fields at 3.6 and 4.5 microns: ELAIS-N1, Lockman Hole (LH), XMM, ELAIS-S1 and Chandra Deep Field South (CDFS). Image mosaics and photometry catalogs (both single band and highly reliable 2-band catalogs) are now available.
The 2013 NEOWISE Post-Cryo Data Release contains 3.4 and 4.6 micron (W1 and W2) Single-exposure image and extracted source data that were acquired by WISE following the exhaustion of solid hydrogen in the satellite's payload inner and outer cryogen tanks. During this period, known as the NEOWISE Post-Cryo survey phase, the WISE optics and focal plane assemblies warmed to 73.5 K, and the W1 and W2 HgCdTe detectors continued to operate with sensitivities close to those achieved during the full cryogenic mission phase. WISE scanned approximately 70% of the sky during the Post-Cryo phase, completing a survey of the inner Main Asteroid Belt, and a second coverage epoch of the inertial sky. The 2013 NEOWISE Post-Cryo Release supersedes the 2012 Post-Cryo Preliminary Release.
The "Spitzer Survey of Stellar Structure in Galaxies" S4G catalog is now available, including photometry, model fit parameters, measurements from the literature, and links to the S4G data for each galaxy. Ellipse fit models are also now available for all 2,352 galaxies.
The COSMOS archive now includes the galaxy density measurements from Scoville et al. (2013).
Planck is a European Space Agency mission with significant NASA involvement. The primary goal of the Planck mission is to measure the intensity and polarization of the sky over a range of frequencies from 30 to 857 GHz (wavelengths of 1 cm to 350 microns) in order to characterize the Cosmic Microwave Background (CMB) radiation. Planck was launched on May 14, 2009 aboard the same rocket that carried the Herschel Space Observatory into space.
BOLOCAM is a 1.1mm instrument at the Caltech Submillimeter Observatory which the BOLOCAM Galactic Plane Survey used to cover 170 square degrees at a wide range of Galactic longitude. The BOLOCAM GPS v2 release includes improved images and a catalog. The new images have improved fidelity and more uniform noise, and cover many new fields.
The "Completing the Spitzer Galactic Plane Survey" GLIMPSE360 DR2 release extends the GLIMPSE catalog coverage from l=169-229 degrees and includes images covering the l=109-174d area.
S4G consists of a sample of 2,352 galaxies, which have been mapped with IRAC channels 1 and 2 (3.6 and 4.5 microns). The first delivery includes all IRAC images, along with ellipse fitting models for over 2,000 galaxies and Galfit models for 200 galaxies.
Finder Chart v2 beta updates IRSA's popular Finder Chart tool to have the same look and feel as other IRSA services such as the Spitzer Heritage Archive and the WISE Image Service. In addition to the more flexible and interactive interface, Finder Chart v2 beta also includes WISE and IRAS data.
The Palomar Transient Factory Photometric Calibrator Catalog v1.0 is a photometrically calibrated catalog of non-variable sources from the PTF observations. The catalog contains calibrated R_PTF-filter magnitudes for about 21 million sources brighter than magnitude 19, over an area of about 11233 square degrees.
The NEOWISE Post-Cryo Preliminary Release consists of over 900,000 3.4 and 4.6
micron images and a database of over 4.9 billion source detections extracted
from those images, acquired between September 29, 2010 and February 1, 2011
after the satellite's solid hydrogen cryogen was completely exhausted.
During this 115 day period, known as the NEOWISE Post-Cryo survey phase, the
telescope and payload warmed to approximately 73.5 K, and the 3.4 and 4.6
micron detectors continued to operate with nearly the same sensitivity as
in the full cryogenic mission phase with only a small increase in the number
of high noise pixels. WISE obtained multiple, independent observations of
approximately 70% of the sky during the Post-Cryo phase, completing a survey
of the inner Main Asteroid Belt and a second coverage epoch of the inertial sky.
A summary of the WISE mission resources is available on the WISE mission page. A quick guide to the Release data products, data access instructions and supporting documentation is available.
The WISE 3-Band Cryo survey phase began on 6 August 2010 following the exhaustion of frozen hydrogen in
the payload's outer cryogen tank. WISE scanned approximately 30% of the sky over the next 54 days while the focal
planes were cooled by hydrogen ice in the inner cryogen tank. The telescope warmed from the 12 K maintained during
the main mission to 45 K. Imaging data in the 3.4, 4.6 and 12 micron bands were acquired, but elevated thermal
emission from the telescope prevented useful data from being collected in the 22 micron band. Release data products
include an Atlas of 5,649 match-filtered, calibrated and coadded image sets, and a Source Working Database containing
positions and 3-band photometry for over 261 million sources detected on the Atlas Images.

RADAR v2.0 represents a significant upgrade from its first v1.0 release. It has a cleaner, more intuitive user interface (RADAR front page). The user may resolve a target name or coordinate position, or run an inventory on a defined region of the sky. The inventory results page includes minor functionality improvements. The data collection page includes table summaries that are more descriptive and user friendly. All of the IRSA data holdings are now fully accessible through RADAR and its data collection manager. The help documentation has been modified accordingly.
In Atlas v1.4, five new data collections have been added: IRTS, SWIRE, Scrapbook, FLS: NOAO Extragalactic R-band data, and NOAO ELAIS N1 R-band data. The previous FirstLook has been renamed FLS_VLA.
In Atlas v1.3, three new data collections have been added: Midcourse Space Experiment (MSX), Spitzer Space Telescope Reserved Observation Catalog Atlas (ROC) and the Spitzer First Look Survey -- Ancillary VLA Data (FirstLook).
New features include a background scaling factor for some datasets in order to better represent the output source overlays and a number of bug fixes. This version also contains software infrastructure changes so that the Spitzer Archive can easily connect to the IRSA Spitzer-related datasets, using Atlas. Please see the change history for more information.
