Description
The first public data release of Euclid provides a glimpse into the superb capabilities of its instruments across all of astrophysics. In this talk, I will present the first catalogue of candidate active galactic nuclei (AGN) in the Q1 fields across 63 sq. deg. We created a multi-wavelength catalog combining GALEX, GAIA, DES, WISE, Spitzer, and DESI data. We find a total of 229,779 AGN candidates across all selections, equivalent to an AGN surface density of 3,641 sq.deg. for 18<I<24.5, and a subsample of 30,422 candidates corresponding to an AGN surface density of 482 sq.deg. when limiting the depth to 18<I<22. The surface density of AGN recovered from this work is in line with predictions based on AGN X-ray luminosity function predictions. I will also discuss future prospects, anticipating the upcoming first data release covering about 2,000 sq.deg.
