Dark matter-baryons elastic coupling
David Figueruelo, Florencia Anabella Teppa Pannia
We consider a cosmological model where dark matter and baryons interact via a pure momentum transfer. We present the foundations of the interaction and derive its main equations. I…
Revisiting observational constraints on coupled exponential quintessence with energy and momentum transfers: degeneracy with massive neutrinos
Jose Beltrán Jiménez, Kiyotomo Ichiki, Xiaolin Liu +2
We investigate the impact of massive neutrinos on cosmological models in which dark energy, described by a quintessence scalar field with an exponential potential, interacts wi…
On the (non-)degeneracy of massive neutrinos and elastic interactions in the dark sector
Jose Beltrán Jiménez, David Figueruelo, Florencia Anabella Teppa Pannia
Cosmological models featuring an elastic interaction in the dark sector at linear order has been shown to provide a promising scenario for alleviating the tension. A natural…
On cosmological signatures of baryons-dark energy elastic couplings
Jose Beltrán Jiménez, Dario Bettoni, David Figueruelo +1
We consider a scenario where dark energy and baryons are dynamically coupled without any energy transfer. In this scenario, the background cosmology is unaffected and, at the pertu…
Evolution of Vacuum Bubbles Embeded in Inhomogeneous Spacetimes
F. A. Teppa Pannia, S. E. Perez Bergliaffa
We study the propagation of bubbles of new vacuum in a radially inhomogeneous background filled with dust or radiation, and including a cosmological constant, as a first step in th…
