The Role of Self Interactions in the Cosmological Evolution of Warm Dark Matter

Rafael Ignacio Yunis, Carlos R. Argüelles, Diana López Nacir +3

In this work we present a summary of recent studies on the effects of elastic self interactions in the evolution of Warm Dark Matter models (WDM), focusing on structure formation a…

Pulsar timing array constraints on spin-2 ULDM

Juan Manuel Armaleo, Diana López Nacir, Federico R. Urban

Ultra-light Dark Matter (ULDM) models are suitable candidates for the cosmological Dark Matter that may leave characteristic imprints in many observables. Among other probes, signa…

Boltzmann hierarchies for self-interacting warm dark matter scenarios

Rafael Yunis, Carlos R. Argüelles, Diana López Nacir

We provide a general framework for self-interacting warm dark matter (WDM) in cosmological perturbations, by deriving from first principles a Boltzmann hierarchy which retains cert…

Secular effects of Ultralight Dark Matter on Binary Pulsars

Diego Blas, Diana López Nacir, Sergey Sibiryakov

Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynam…

Binary Pulsars as probes for Spin-2 Ultralight Dark Matter

Juan Manuel Armaleo, Diana López Nacir, Federico R. Urban

Binary pulsars can be excellent probes of ultra-light dark matter. We consider the scenario where the latter is represented by a spin-2 field. The coherent oscillations of the dark…

To the sphere and back again: de Sitter infrared correlators at NTLO in 1/N

Diana López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta

We analyze the infrared behavior of the two and four-point functions for the massless model in Lorentzian de Sitter spacetime, using the expansion. Our approach is bas…
