Testing f(R) gravity models with quasar X-ray and UV fluxes
Matías Leizerovich, Lucila Kraiselburd, Susana J. Landau +1
Recently, Active Galactic Nuclei (AGNs) have been proposed as standardizable candles, thanks to an observed non-linear relation between their X-ray and optical-ultraviolet (UV) lum…
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…
Self-Interacting Dark Matter in Cosmology: accurate numerical implementation and observational constraints
Rafael Yunis, Carlos R. Argüelles, Claudia G. Scóccola +2
This paper presents a systematic and accurate treatment of the evolution of cosmological perturbations in self-interacting dark matter models, for particles which decoupled from th…
