Probing New Degrees of Freedom with the Universal Tail of Primordial Black Hole Mass Functions
Kaustubh Agashe, Jae Hyeok Chang, Steven J. Clark +3
The primordial black hole (PBH) mass function today develops a low-mass evaporation tail whose shape is universal with respect to the initial PBH mass distribution. This universali…
Direct Collapse Black Hole Candidates from Decaying Dark Matter
Yash Aggarwal, James B. Dent, Philip Tanedo +1
Injecting 1-13.6 eV photons into the early universe can suppress the molecular hydrogen abundance and alter the star formation history dramatically enough to produce direct collaps…
Gravitational wave signatures of primordial black hole accretion during early matter domination
Rouzbeh Allahverdi, James B. Dent, Ngo Phuc Duc Loc +1
We present a scenario in which primordial black holes (PBHs) form in a post-inflationary radiation-dominated (RD) phase and then experience significant accretion during a phase of…
Light in the Shadows: Primordial Black Holes Making Dark Matter Shine
Kaustubh Agashe, Manuel Buen-Abad, Jae Hyeok Chang +4
We consider the possibility of indirect detection of dark sector processes by investigating a novel form of interaction between ambient dark matter (DM) and primordial black holes…
Multi-messenger Probes of Asteroid Mass Primordial Black Holes: Superradiance Spectroscopy, Hawking Radiation, and Microlensing
James B. Dent, Bhaskar Dutta, Tao Xu
Superradiance provides a unique opportunity for investigating dark sectors as well as primordial black holes, which themselves are candidates for dark matter over a wide mass range…
