New COSMOS catalog is out!
The new COSMOS catalog is out and its accompanying paper is accepted!
The catalog contains 1 million sources measured in more than 30 photometric bands from the UV to the infrared. For the extraction of the photometry, our international team applied a new prior-based method to go even deeper and to obtain more robust measurements for blended sources. The catalog also contains photometric redshifts and other physical properties of the galaxies measured from their photometry using spectral energy distribition (SED) fitting codes like LePhare and Eazy.
This catalog is a major milestone for COSMOS, combining its multi-wavelength data consistently, and opening up new avenues to explore galaxy evolution.
