Backwards Gamma-Ray Bursts: Searching for Exploding Primordial Black Holes in Short-Duration GRB Catalogs
Stefano Profumo, Kally Wen
We present a systematic search for signatures of terminal black-hole evaporation in short gamma-ray burst (sGRB) catalogs. An exploding primordial black hole (PBH) undergoing final…
Structure Formation with Dark Magnetohydrodynamics
Pierce Giffin, Andrew Liu, Jeremias Boucsein +4
Long-range interactions in the dark sector can give rise to collective plasma phenomena that are capable of modifying the evolution of dark matter halos. We present the first study…
Chemical and Kinetic Equilibrium in Cosmology: Facts and Myths
Stefano Profumo
We clarify that chemical and kinetic equilibration in the early Universe are distinct: neither implies the other, and the ordering of their decouplings need not be universal. We il…
A Multi-Wavelength Survey of Transient Lensing Opportunities for Primordial Black Hole Searches
Stefano Profumo
Gravitational lensing of short astrophysical transients provides a uniquely direct avenue for searching for primordial black holes (PBHs) across a vast range of masses. While past…
Primordial black holes versus their impersonators at gravitational wave observatories
Andrea Begnoni, Stefano Profumo
The detection of primordial black holes (PBHs) would mark a major breakthrough, with far-reaching implications for early universe cosmology, fundamental physics, and the nature of…
Precision gravity constraints on large dark sectors
Christopher Ewasiuk, Stefano Profumo
General relativity, treated as a low energy effective field theory, predicts quantum corrections to Newtons law of gravitation arising from loops of matter and graviton fields. Whi…
Primordial Black Holes and the First Stars
Julia Monika Koulen, Stefano Profumo, Nolan Smyth
Primordial black holes (PBHs) constitute a compelling dark matter candidate whose gravitational effects could significantly influence early cosmic structure formation. We investiga…
Dark-sector modifications to Kerr and Reissner-Nordstrom black hole evaporation
Christopher Ewasiuk, Stefano Profumo
We present a comprehensive comparative analysis of the evaporation dynamics of Schwarzschild, Kerr, and Reissner- Nordstrom black holes, focusing on the evolution of their mass, ch…
A Louder Gravitational Wave Bang from a Fast-Expanding Universe
Lucas Brown, Stefano Profumo, Aditi Gangadharan +1
A strong first-order phase transition in a dark sector may produce all or part of the low-frequency gravitational wave signal recently reported by the NANOGrav Collaboration and ot…
Dark Baryon Black Holes
Stefano Profumo
We explore a novel mechanism for dark matter production through the formation of light black holes from the collapse of dark baryons in confining SU(N) gauge theories in the large…
Dark Matter from quasi-de Sitter Horizons
Stefano Profumo
Assuming that (1) the universe underwent a post-inflationary accelerated expansion phase driven by a fluid with equation of state and , that (2) the cosmic horizo…
