The Clustering of Little Red Dots from Ultra-Strongly Self-Interacting Dark Matter
M. Grant Roberts, Aarna Garg, Tesla Jeltema +1
We predict the effective clustering bias parameter, , at for Little Red Dots (LRDs) seeded by Ultra-Strongly Self-Interacting Dark Matter (uSIDM). From our m…
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…
Ultra-Strongly Self-Interacting Dark Matter: From Phenomenology to Astrophysical Observables
M. Grant Roberts, Wolfgang Altmannshofer, Pierce Giffin +1
We develop a minimal, testable framework for two-component self-interacting dark matter (SIDM) in which a dominant, moderately self-interacting species coexists with an ultra-stron…
The Cosmic Horizon of Neutrinos
James Fardeen, Stefano Profumo, M. Grant Roberts
The persistent discrepancy between the experimental measurement and the Standard Model (SM) prediction of the muon's anomalous magnetic moment remains one of the most int…
Little Red Dots from Ultra-Strongly Self-Interacting Dark Matter
M. Grant Roberts, Lila Braff, Aarna Garg +2
We investigate the possibility that the recently identified population of high-redshift, obscured quasars - known as "Little Red Dots" (LRDs) - originates from early black hole see…
Gravothermal collapse and the diversity of galactic rotation curves
M. Grant Roberts, Manoj Kaplinghat, Mauro Valli +1
The rotation curves of spiral galaxies exhibit a great diversity that challenge our understanding of galaxy formation and the nature of dark matter. Previous studies showed that in…
On the Impact of Dark Matter Scattering on the Trajectory of High-Energy Cosmic Rays
Stefano Profumo, M. Grant Roberts, Shashank Dharanibalan
We study the impact on the trajectory of high-energy cosmic-ray protons of scattering off the cosmic dark matter. We compute the scattering angle as a function of the cosmic-ray en…
