FIDEL Spitzer and Ancillary Data
Far-Infrared Deep Extragalactic Legacy Survey (FIDEL) contains sensitive and extensive far-infrared deep field observations with Spitzer to detect warm dust emission from hundreds of relatively ordinary starburst galaxies and active galactic nuclei at redshifts of 1 to 2 (7 to 10 billion years ago), and thousands more nearby. The survey also detected tens of thousands of high redshift objects at mid-infrared wavelengths. The program obtained data in three fields on the sky. The bulk of the data is in two fields, the Extended Chandra Deep Field South (ECDFS) and the Extended Groth Strip (EGS). A smaller amount of additional data was obtained in the GOODS-North area.
You can get a close-up map by clicking on any of the data regions on the images below, or by typing a coordinate below.
The second delivery (DR2) of the Spitzer data from the FIDEL Legacy Project, are available here using spatial and visualization tools. DR2 contains MIPS image mosaics for all three FIDEL fields.
The sky coverage is shown on the FIDEL MIPS images above. Either type in a coordinate or click within the red outlined region to get a close-up of the area; the size of the search is adjustable. Search results will include cutout images cropped to the search box as well as the associated original images which overlap the area of interest.
FIDEL image "cutouts" in FITS and JPEG format are accessible using IRSA's Cutouts Service.
