Same Events, Weaker Bound: Model Dependence in Magellanic Microlensing Limits on Primordial Black Holes
David Morales-Zapien, Lucas Brown, Stefano Profumo
OGLE microlensing of the Magellanic Clouds sets the leading bounds on primordial black holes (PBHs) as dark matter from to . Holding the detected events…
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…
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…
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…
A New Census of the Universe's Entropy
Stefano Profumo, Liam Colombo-Murphy, Gabriela Huckabee +4
The question of what is the total entropy of the universe, how it compares to the maximal entropy of de Sitter space, and how it is distributed across the universe's components, be…
Black Holes from Fermi Ball Collapse
Yifan Lu, Zachary S. C. Picker, Stefano Profumo +1
Fermi balls are non-topological solitons that can naturally form in an early universe containing a dark sector with heavy fermions and an attractive interaction mediated by a light…
