When Tiny Halos Stir Spacetime: Gravitational Waves from Fifth-Force Mergers
Xinpeng Wang, Yifan Lu, Zachary S. C. Picker +2
Dark matter fermions interacting via attractive fifth forces mediated by a light mediator can form dark matter halos in the very early universe. We show that bound systems composed…
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…
Structure Formation after Reheating: Supermassive Primordial Black Holes and Fermi Ball Dark Matter
Marcos M. Flores, Yifan Lu, Alexander Kusenko
In the presence of (relatively) long-range forces, structures can form even during the radiation dominated era, leading to compact objects, such as Fermi balls or primordial black…
