IR Black Hole Instabilities Trigger Species-Scale Particle Production

Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst +1

We propose a novel UV-IR mechanism in quantum gravity in which black hole instabilities act as a bridge to the most ultraviolet sector of the theory. Specifically, we argue that wh…

Massive neutrinos and interacting dark matter look alike through the lens of lensing

Luis A. Anchordoqui, Danny Marfatia, Jorge F. Soriano

We demonstrate that the suppression in the lensing power spectrum of the cosmic microwave background (CMB) caused by massive neutrinos can be mimicked by dark matter-baryon interac…

New insights on a sign-switching

Jorge F. Soriano, Shimon Wohlberg, Luis A. Anchordoqui

The proposal for a sudden sign-switching cosmological constant in the local universe, emulating a phase transition from anti-de Sitter (AdS) to de Sitter (dS) space, has marked…
