Gas Accretion versus BH Merger driven Growth Modes of Supermassive Black Holes and Implications for the Little Red Dots
Paramita Barai
We investigate the growth of central supermassive black holes in galaxies, aiming to distinguish between gas accretion versus BH merger-driven growth modes. By performing and analy…

The evolution of obscured AGN across cosmic time -- A large quasar survey for the 2040s
Tanya Urrutia, Darshan Kakkad, Paula Sánchez-Sáez +21
We propose a large quasar demographic optical multi-object spectroscopic (MOS) survey targeting over 50 million AGN candidates up to the highest redshifts possible in the optical (…

Exploring the evolution of a dwarf spheroidal galaxy with SPH simulations: II. AGN feedback
R. Hazenfratz, P. Barai, G. A. Lanfranchi +1
We investigate AGN feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of t…
