Off-center black hole seed formation? Implications for high and low redshift massive black holes
David Izquierdo-Villalba, Daniele Spinoso, Marta Volonteri +3
Recent studies show that light seeds of black holes, which grow into massive black holes (MBHs) over time, often struggle to remain at the centers of their birthplaces in high-reds…

Alberto Torralba-Torregrosa, Pablo Renard, Daniele Spinoso +17
We present the Lyman- (Ly) and ultraviolet (UV) luminosity function (LF), in bins of redshift, of quasars selected in the Physics of the Accelerating Universe Survey (PAUS).…
A link to the past: characterizing wandering black holes in Milky Way-type galaxies
Julen Untzaga, Silvia Bonoli, David Izquierdo-Villalba +2
A population of non-stellar black holes (100 M) has been long predicted to wander the Milky Way. We aim to characterize this population by using the L-Galaxies s…
