Polarisability and magnetisation of electrically -mouflaged objects: the Born-Infeld ModMax case study
Jose Beltrán Jiménez, Dario Bettoni, Philippe Brax
We consider a family of non-linear theories of electromagnetism that interpolate between Born-Infeld at small distances and ModMax at large distances. These models are duality inva…
GASP XXXVII: The Most Extreme Jellyfish Galaxies Compared to Other Disk Galaxies in Clusters, an HI Study
N. Luber, A. Müller, J. H. van Gorkom +19
We present the results of a VLA HI imaging survey aimed at understanding why some galaxies develop long extraplanar H tails, becoming extreme jellyfish galaxies. The observation…
Inhomogeneous Hubble diagram from vector K-mouflage
Jose Beltran Jimenez, Dario Bettoni, Philippe Brax
In this Letter we construct the Hubble diagram for a Universe where dark matter is universally charged under a dark non-linear electromagnetic force which features a screening mech…
J-PAS: Forecasts for dark matter - dark energy elastic couplings
David Figueruelo, Miguel Aparicio Resco, Florencia A. Teppa Pannia +21
We consider a cosmological model where dark matter and dark energy feature a coupling that only affects their momentum transfer in the corresponding Euler equations. We perform a f…
Velocity-dependent interacting dark energy and dark matter with a Lagrangian description of perfect fluids
Jose Beltrán Jiménez, Dario Bettoni, David Figueruelo +2
We consider a cosmological scenario where the dark sector is described by two perfect fluids that interact through a velocity-dependent coupling. This coupling gives rise to an int…
Screening away the tension
Jose Beltran Jimenez, Dario Bettoni, Philippe Brax
This Essay explores consequences of a dark non-linear electromagnetic sector in a Universe with a net dark charge for matter. The cosmological dynamics can be described by a Lemaît…
