Description

Little Red Dots (LRDs) are one of the most intriguing galaxy populations recently identified by JWST at high redshifts (typically z>4), and they are characterized by 'V-shaped' spectral energy distributions and compact morphologies. Whilst JWST studies of LRDs are typically constrained to relatively small sky areas, Euclid gives us the possibility to search for luminous cases in its wider area galaxy surveys. In this talk I will present the results of our pilot study of V-shaped SED sources (including LRDs), identified using a combination of Euclid and Spitzer photometry, in the Euclid deep survey of the COSMOS field. I will show how these objects constrain the knee of the LRD luminosity function at high z, and compare their photometric properties to those of the so-called Blue Dust-Obscured Galaxies (BlueDOGS), which are rarer sources at z=2-3.
