Mapping parameters of idealised hydrodynamic galaxy simulations to bar properties: a case study with the RAMSES code
Srikanth T. Nagesh, Benoit Famaey, Jonathan Freundlich +4
Cosmological simulations with high spatial resolution often struggle to reproduce the observed fraction of galactic bars across redshift and may produce bars that are too short. To…
A bar stability criterion distinguishing between modified gravity and dark matter in galaxies
Tahere Kashfi, Mahmood Roshan, Virginia Cuomo +3
This paper presents a study on the distinguishability of dark matter and Modified Newtonian Dynamics (MOND) at galactic scales based on the stability criterion proposed by Efstathi…
Globular cluster orbital decay in dwarf galaxies with MOND and CDM: Impact of supernova feedback
M. Bílek, F. Combes, S. T. Nagesh +1
Dynamical friction works very differently for Newtonian gravity with dark matter and in modified Newtonian dynamics (MOND). While the absence of dark matter considerably reduces th…
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…
Do old globular clusters in low mass galaxies disprove modified gravity?
Michal Bílek, Hongsheng Zhao, Benoit Famaey +6
The controversy "dark matter vs. modified gravity" constitutes a major topic of discussion. It was proposed that dynamical friction could be used to discriminate between the two al…
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…
Overestimated inclinations of Milgromian disc galaxies: the case of the ultradiffuse galaxy AGC 114905
Indranil Banik, Srikanth Togere Nagesh, Hosein Haghi +2
We present hydrodynamical star-forming simulations in the Milgromian dynamics (MOND) framework of a gas-rich disc galaxy with properties similar to AGC 114905, which has recently b…
Origin of the spectacular tidal shells of galaxy NGC474
Michal Bílek, Jérémy Fensch, Ivana Ebrová +4
The lenticular galaxy NGC474 hosts a rich system of tidal shells and streams, some of which are exceptionally bright. Two teams recently presented spectroscopic observations of the…
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…
Constraints on the star formation histories of galaxies in the Local Cosmological Volume
Pavel Kroupa, Moritz Haslbauer, Indranil Banik +2
The majority of galaxies with current star-formation rates (SFRs), SFRo >= 10^-3 Msun/yr, in the Local Cosmological Volume where observations should be reliable, have the property…
