Isotropization of a rotating and longitudinally expanding scalar system
Margaret E. Carrington, Gabor Kunstatter, Christopher Phillips +1
We present numerical simulations for the evolution of an expanding system of massless scalar fields with quartic coupling. By setting a rotating, non-isotropic initial configuratio…
Extended primordial black hole mass functions with a spike
Juan Magaña, Marco San Martín, Joaquín Sureda +3
We introduce a modification of the Press-Schechter formalism aimed to derive general mass functions for primordial black holes (PBHs). In this case, we start from primordial power…
Dark matter from primordial black holes would hold charge
Ignacio J. Araya, Nelson D. Padilla, Marcelo E. Rubio +3
We explore the possibility that primordial black holes (PBHs) contain electric charge down to the present day. We find that PBHs should hold a non-zero net charge at their formatio…
