On the initial conditions of the HDM cosmological model
Nick Samaras, Sebastian Grandis, Pavel Kroupa
The HDM is the only cosmological model based on Milgromian Dynamics (MOND) with available structure formation simulations. While MOND accounts for galaxies, with a priori predic…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Challenges to a sharp change in as a solution to the Hubble tension
Indranil Banik, Harry Desmond, Nick Samaras
It has been proposed that the gravitational constant abruptly decreased around 130 Myr ago, making Type Ia supernovae (SNe) in the Hubble flow intrinsically brighter than those…
Constraints on the Hubble and matter density parameters with and without modelling the CMB anisotropies
Indranil Banik, Nick Samaras
We consider constraints on the Hubble parameter and the matter density parameter from: (i) the age of the Universe based on old stars and stellar populations…
The many tensions with dark-matter based models and implications on the nature of the Universe
Pavel Kroupa, Eda Gjergo, Elena Asencio +6
(Abridged) Fundamental tensions between observations and dark-matter based cosmological models have emerged. This updated review has two purposes: to explore new tensions that have…
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…
