Formation of primordial black holes through Q-balls
Shinta Kasuya, Masahiro Kawasaki, Alexander Kusenko +1
We study the primordial black hole (PBH) formation from Q-balls that are non-topological solitons in scalar field theories. We develop a formula for calculating the density perturb…
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…
Primordial Black Hole Triggered Type Ia Supernovae I: Impact on Explosion Dynamics and Light Curves
Shing-Chi Leung, Seth Walther, Ken'ichi Nomoto +1
Primordial black holes (PBHs) in the asteroid-mass window are compelling dark matter candidates, made plausible by the existence of black holes and by the variety of mechanisms of…
Neutrino masses, matter-antimatter asymmetry, dark matter, and supermassive black hole formation explained with Majorons
Yifan Lu, Zachary S. C. Picker, Alexander Kusenko +1
The spontaneous breaking of a global lepton number symmetry can result in a (pseudo) Nambu-Goldstone boson known as the Majoron. We study a singlet Majoron model that couples to tw…
