The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
Anisotropic deformations in a class of projectively-invariant metric-affine theories of gravity
Jose Beltrán Jiménez, Daniel de Andrés, Adrià Delhom
Among the general class of metric-affine theories of gravity, there is a special class conformed by those endowed with a projective symmetry. Perhaps the simplest manner to realise…
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…
Minkowski space in gravity
Jose Beltran Jimenez, Alexey Golovnev, Tomi Koivisto +1
The full set of solutions of gravity with the Minkowski metric is considered in this note. At the 4-th order in perturbations around the trivial tetrad solution, a new mode…
Charged Dark Matter and the tension
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax
We consider cosmological models where dark matter is charged under a dark Abelian gauge field. This new interaction is repulsive and competes with gravity on large scales and in th…
