Satellite stellar-to-halo mass relations in primordial black hole universes
Patricio Colazo, Nelson Padilla, Federico Stasyszyn
Primordial black holes (PBHs), in particular with a fixed-conformal-time (FCT) extended mass function, can modify small-scale structure through enhanced primordial power and discre…

Excess of substructure due to primordial black holes
Patricio Colazo, Nelson Padilla, Federico Stasyszyn
This paper explores the impact of primordial black holes (PBHs) on the abundance of low-mass haloes and subhaloes in the dark and low-stellar-mass regime, and examines how these ef…

Structure formation with primordial black holes to alleviate early star formation tension revealed by JWST
P. E. Colazo, F. Stasyszyn, N. Padilla
This Letter explores the potential role of primordial black holes (PBHs) to address cosmological tensions as the presence of more massive than expected galaxies at high redshifts,…
