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 the presence of non-zero lepton and baryon asymmetries. Considering different scenarios, we determine the equation of sta…
Primordial Black Holes as Cosmic Architects: Imprints of an extended mass function
Alberto Magaraggia, Nico Cappelluti, Günther Hasinger +2
Primordial black holes (PBHs) remain compelling dark-matter candidates and possible relics of early-Universe physics, with observable imprints across both cosmological structure fo…
Primordial Black Hole mass growth from neutrinos during the radiation era
Maël Gonin
We present a new picture of primordial black holes mass evolution through neutrino absorption. Using semi-classical approach and a closer look at the kinetic of the early plasma we…
Primordial Black Holes Formation Beyond the Standard Cosmic QCD Transition
Maël Gonin, Oleksii Ivanytskyi, David Blaschke +1
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter (DM) candidates. We elucidate the role of phase…
Primordial black-hole formation and heavy r-process element synthesis from the cosmological QCD transition. Two aspects of an inhomogeneous early Universe
M. Gonin, G. Hasinger, D. Blaschke +2
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter candidates. We elucidate the role of phase trans…
