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 a…
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…
Cosmological simulations of a momentum coupling between dark matter and quintessence
Daniela Palma, Graeme N. Candlish
Dark energy is frequently modelled as an additional dynamical scalar field component in the Universe, referred to as "quintessence", which drives the late-time acceleration. Furthe…
Hydrodynamical structure formation in Milgromian cosmology
Nils Wittenburg, Pavel Kroupa, Indranil Banik +2
We present the first hydrodynamical cosmological simulations in the HDM framework based on Milgromian dynamics (MOND) with light (11~eV) sterile neutrinos. HDM can explain th…
The large-scale structure from non-Gaussian primordial perturbations
G. A. Peña, G. N. Candlish
The late-time effect of primordial non-Gaussianity offers a window into the physics of inflation and the very early Universe. In this work we study the consequences of a particular…
The velocity field in MOND cosmology
G. N. Candlish
The recently developed code for N-body/hydrodynamics simulations in Modified Newtonian Dynamics (MOND), known as RAyMOND, is used to investigate the consequences of MOND on structu…
