Primordial Asymmetries, Primordial Equation of State & Primordial Black Holes
Maël Gonin, Julien Froustey, Albert Escrivà +3
We study the thermal history of the primordial Universe in presence of non-zero lepton and baryon asymmetries. Considering different scenarios, we determine the equation of state (…
Parameter Estimation on LIGO-Virgo-KAGRA O4a Binary Merger Triggers with Sub-solar Mass Components
Nelson Christensen, Nelson Christensen. Neil Cornish, Neil Cornish +3
The LIGO-Virgo-KAGRA collaboration has reported the results for searches for sub-solar mass components in compact binary coalescence during observing run O4a. No detection candidat…
Primordial Black Holes as Seeds for Extremely Overmassive AGN Observed by JWST
Saiyang Zhang, Boyuan Liu, Volker Bromm +1
The James Webb Space Telescope (JWST) has recently identified Abell 2744-QSO1 as a compact, metal-poor, black hole (BH) dominated galaxy at . This system exhibits an ext…
How do Massive Primordial Black Holes Impact the Formation of the First Stars and Galaxies?
Saiyang Zhang, Boyuan Liu, Volker Bromm +3
We investigate the impact of massive primordial black holes (PBHs; ) on the star formation and first galaxy assembly process using high-resolution hy…
