The impact of black hole feedback on the UV luminosity and stellar mass assembly of high-redshift galaxies

Olmo Piana, Pratika Dayal, Tirthankar Roy Choudhury

We employ the Delphi semi-analytical model to study the impact of black hole growth on high-redshift galaxies, both in terms of the observed UV luminosity and of the star formation…
