CLASH and HOP Data Releases

Spitzer IRAC image of the galaxy cluster MACS J0717+3745 from the CLASH program

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.

PEP Data Release

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.

This image combines WISE and Spitzer data to show dust associated with the blast wave from RCW 86. The supernova was recorded by Chinese astronomers in 185 AD, making it the oldest documented supernova.
