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…
Simulations of star forming main sequence galaxies in Milgromian gravity
Srikanth T. Nagesh, Pavel Kroupa, Indranil Banik +6
We conduct hydrodynamical MOND simulations of isolated disc galaxies over the stellar mass range using the adaptive mesh refinement code \texts…
The formation of early-type galaxies through monolithic collapse of gas clouds in Milgromian gravity
Robin Eappen, Pavel Kroupa, Nils Wittenburg +2
Studies of stellar populations in early-type galaxies (ETGs) show that the more massive galaxies form earlier and have a shorter star formation history (SFH). In this study, we inv…
The High Fraction of Thin Disk Galaxies Continues to Challenge ΛCDM Cosmology
Moritz Haslbauer, Indranil Banik, Pavel Kroupa +2
Any viable cosmological framework has to match the observed proportion of early- and late-type galaxies. In this contribution, we focus on the distribution of galaxy morphological…
The Phantom of RAMSES user guide for galaxy simulations using Milgromian and Newtonian gravity
Srikanth T. Nagesh, Indranil Banik, Ingo Thies +5
This document describes the general process of setting up, running, and analysing disc galaxy simulations using the freely available program Phantom of RAMSES (PoR). This implement…
The formation of exponential disk galaxies in MOND
Nils Wittenburg, Pavel Kroupa, Benoit Famaey
The formation and evolution of galaxies is highly dependent on the dynamics of stars and gas, which is governed by the underlying law of gravity. To investigate how the formation a…
