Finite size effects in DBI and Born-Infeld for screened spherically symmetric objects
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax +2
We study finite size effects on the linear response of spherically symmetric objects in Born-Infeld (BI) electromagnetism and Dirac-Born-Infeld (DBI) scalar field theories. Previou…
Updates on dipolar anisotropy in local measurements of the Hubble constant from Cosmicflows-4
Vincenzo Salzano, J. Beltrán Jiménez, Dario Bettoni +2
We investigate the angular anisotropy of the Hubble constant using the Cosmicflows-4 catalogue, with particular emphasis on three issues often treated only implicitly in the litera…
On Evidence for Elastic Interactions in the Dark Sector
Jose Beltrán Jiménez, Dario Bettoni, David Figueruelo +1
The increasing quality of cosmological data has revealed some tensions that could be signalling the necessity of incorporating new physics into our cosmological model. One particul…
Resilience of DBI screened objects and their ladder symmetries
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax
Scalar field theories with a shift symmetry come equipped with the -mouflage (or kinetic screening) mechanism that suppresses the scalar interaction between massive objects belo…
