Axion dark matter in the time of primordial black holes

N Bernal, F Hajkarim, Y Xu - Physical Review D, 2021 - APS
We investigate the production of QCD axion dark matter in a nonstandard cosmological era
triggered by primordial black holes (PBHs) that fully evaporate before the onset of BBN …

ALP dark matter in a primordial black hole dominated universe

N Bernal, YF Perez-Gonzalez, Y Xu, Ó Zapata - Physical Review D, 2021 - APS
We investigate the phenomenological consequences of axionlike particle (ALP) dark matter
with an early matter domination triggered by primordial black holes (PBHs). We focus on …

Direct detection of light dark matter from evaporating primordial black holes

R Calabrese, M Chianese, DFG Fiorillo, N Saviano - Physical Review D, 2022 - APS
The direct detection of sub-GeV dark matter interacting with nucleons is hampered by the
low recoil energies induced by scatterings in the detectors. This experimental difficulty is …

Cogenesis of Baryon asymmetry and gravitational dark matter from primordial black holes

B Barman, D Borah, SJ Das… - Journal of Cosmology and …, 2022 - iopscience.iop.org
We propose a scenario where dark matter (DM) with a wide mass range from a few keV to
PeV can be produced solely from evaporating primordial black holes (PBH), while being …

[HTML][HTML] Probing high scale seesaw and PBH generated dark matter via gravitational waves with multiple tilts

D Borah, SJ Das, R Roshan - Nuclear Physics B, 2024 - Elsevier
We propose a scenario where a high scale seesaw origin of light neutrino mass and
gravitational dark matter (DM) in MeV-TeV ballpark originating from primordial black hole …

Successful cogenesis of baryon and dark matter from memory-burdened PBH

D Borah, N Das - arXiv preprint arXiv:2410.16403, 2024 - arxiv.org
We study the possibility of producing the observed baryon asymmetry of the Universe (BAU)
and dark matter (DM) from evaporating primordial black holes (PBH) beyond the semi …

Gravitational wave signatures of cogenesis from a burdened PBH

B Barman, MR Haque, Ó Zapata - arXiv preprint arXiv:2405.15858, 2024 - arxiv.org
We explore the possibility of explaining the observed dark matter (DM) relic abundance,
along with matter-antimatter asymmetry, entirely from the evaporation of primordial black …
