From galactic bars to the Hubble tension: weighing up the astrophysical evidence for Milgromian gravity
Indranil Banik, Hongsheng Zhao
Astronomical observations reveal a major deficiency in our understanding of physics the detectable mass is insufficient to explain the observed motions in a huge variety of sys…
Detailed numerical implementation of the wide binary test
Indranil Banik, Charalambos Pittordis, Will Sutherland
The observed flat rotation curves of galaxies are among a number of astrophysical phenomena which require a larger acceleration than can be provided by the Newtonian gravity of the…
The Kennicutt-Schmidt law and the main sequence of galaxies in Newtonian and Milgromian dynamics
Akram Hasani Zonoozi, Patrick Lieberz, Indranil Banik +2
The Kennicutt-Schmidt law is an empirical relation between the star formation rate surface density () and the gas surface density () in disc galaxies. The relatio…
Fast galaxy bars continue to challenge standard cosmology
Mahmood Roshan, Neda Ghafourian, Tahere Kashfi +5
Many observed disc galaxies harbour a central bar. In the standard cosmological paradigm, galactic bars should be slowed down by dynamical friction from the dark matter halo. This…
On the absence of backsplash analogues to NGC 3109 in the CDM framework
Indranil Banik, Moritz Haslbauer, Marcel S. Pawlowski +2
The dwarf galaxy NGC 3109 is receding 105 km/s faster than expected in a CDM timing argument analysis of the Local Group and external galaxy groups within 8 Mpc (Banik \& Zhao 2…
Barred spiral galaxies in modified gravity theories
Mahmood Roshan, Indranil Banik, Neda Ghafourian +4
When bars form within galaxy formation simulations in the standard cosmological context, dynamical friction with dark matter (DM) causes them to rotate rather slowly. However, almo…
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…
