The redshift dependence of the inferred in a local void solution to the Hubble tension
Sergij Mazurenko, Indranil Banik, Pavel Kroupa
Galaxy number counts suggest that we are located within the Gpc-scale KBC void. The Hubble tension might arise due to gravitationally driven outflow from this void, as explored in…
The distribution and morphologies of Fornax Cluster dwarf galaxies suggest they lack dark matter
E. Asencio, I. Banik, S. Mieske +3
Due to their low surface brightness, dwarf galaxies are particularly susceptible to tidal forces. The expected degree of disturbance depends on the assumed gravity law and whether…
The Magellanic Clouds are very rare in the IllustrisTNG simulations
Moritz Haslbauer, Indranil Banik, Pavel Kroupa +2
The Large and Small Magellanic Cloud (LMC and SMC) form the closest interacting galactic system to the Milky Way, therewith providing a laboratory to test cosmological models in th…
Strong constraints on the gravitational law from DR3 wide binaries
Indranil Banik, Charalambos Pittordis, Will Sutherland +4
We test Milgromian dynamics (MOND) using wide binary stars (WBs) with separations of kAU. Locally, the WB orbital velocity in MOND should exceed the Newtonian prediction by…
