Signatures of Extended Dark Energy Parametrisations in Structure Formation under Background Constraints
Greco A. Peña, Mario H. Amante, Javier Chagoya +3
We study structure formation in alternative cosmological models constrained by background observations, including CDM, wCDM, the Chevallier-Polarski-Linder parametrisation and…

The effects on structure of a momentum coupling between dark matter and quintessence
G. N. Candlish, Y. Jaffé
Given the mysterious nature of dark matter and dark energy, and the persistent tensions in cosmological data, it is worthwhile exploring more exotic physics in the dark sector, suc…

Simulations of cluster ultra-diffuse galaxies in MOND
Srikanth T. Nagesh, Jonathan Freundlich, Benoit Famaey +4
Ultra-diffuse galaxies (UDGs) in the Coma cluster have velocity dispersion profiles that are in full agreement with the predictions of Modified Newtonian Dynamics (MOND) in isolati…
