From Axion Detection to Dark Matter Astronomy
Jae Hyeok Chang, Stefano Profumo
A global haloscope network could turn an axion discovery into astronomy of dark matter substructure and transients. We combine interferometric phase, spatial coherence, and spectro…
Charting Dark Matter down to the neutrino floor/fog in the 2HD+a scenario
Giorgio Arcadi, Abdelhak Djouadi, Stefano Profumo
Next-generation direct detection experiments will probe dark matter (DM) scattering cross-sections deep into the neutrino fog, the regime where coherent neutrino scattering becomes…
Are Primordial Black Holes a Natural Dark Matter Candidate?
Stefano Profumo
Primordial black holes (PBHs) in the asteroid-mass window (- g) can account for all of the dark matter without violating any observational constraint, yet are rou…
Probing Planck-Scale Physics with High-Frequency Gravitational Waves
Stefano Profumo
We develop a framework for testing quantum gravity through the stochastic gravitational-wave background produced by evaporating near-Planck-mass primordial black holes. Because gra…
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…
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…
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…
Super-exponential Primordial Black Hole Production via Delayed Vacuum Decay
Yanda Wu, Stefano Profumo
If a cosmological first-order phase transition occurs sufficiently slowly, delayed vacuum decay may lead to the formation of primordial black holes. Here we consider a simple model…
Black Hole Explosions as Probes of New Physics
Kevin Federico, Stefano Profumo
The final stage of black hole evaporation is a potent probe of physics beyond the Standard Model: Hawking-Bekenstein radiation may be affected by quantum gravity "memory burden eff…
