Dark matter production from evaporation of regular primordial black holes
Ngo Phuc Duc Loc
We point out that a simple redefinition of the regularizing parameter in regular black hole (RBH) metrics can preserve the self-similarity of the evaporation process. This implies…
Constraining regular primordial black holes with isocurvature gravitational waves
Ngo Phuc Duc Loc
We find the constraint on the population of ultra-light regular primordial black holes (RPBHs) by using isocurvature gravitational waves (GW). If ultra-light RPBHs dominated the ea…
Gravitational wave signatures of primordial black hole accretion during early matter domination
Rouzbeh Allahverdi, James B. Dent, Ngo Phuc Duc Loc +1
We present a scenario in which primordial black holes (PBHs) form in a post-inflationary radiation-dominated (RD) phase and then experience significant accretion during a phase of…
Gravitational waves from burdened primordial black holes dark matter
Ngo Phuc Duc Loc
Primordial black holes (PBHs) are the natural candidate of dark matter (DM) as they only interact gravitationally and can evade any experiments on earth. In the standard semiclassi…
