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…
A simultaneous solution to the Hubble tension and observed bulk flow within 250 Mpc
Sergij Mazurenko, Indranil Banik, Pavel Kroupa +1
The cold dark matter (CDM) standard cosmological model is in severe tension with several cosmological observations. Foremost is the Hubble tension, which exceeds confid…
The El Gordo galaxy cluster challenges ΛCDM for any plausible collision velocity
E. Asencio, I. Banik, P. Kroupa
El Gordo (ACT-CL J0102-4915) is an extraordinarily large and bright galaxy cluster collision. In a previous study, we found that El Gordo is in tension with the CDM stand…
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…
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…
A massive blow for CDM the high redshift, mass, and collision velocity of the interacting galaxy cluster El Gordo contradicts concordance cosmology
E. Asencio, I. Banik, P. Kroupa
El Gordo (ACT-CL J0102-4915) is an extremely massive galaxy cluster ( ) at redshift composed of two subclusters with mass r…
The KBC void and Hubble tension contradict CDM on a Gpc scale Milgromian dynamics as a possible solution
Moritz Haslbauer, Indranil Banik, Pavel Kroupa
The KBC void is a local underdensity with the observed relative density contrast between 40 and 300 Mpc around the Local Group. If mass is con…
Scale-invariant dynamics in the Solar System
Indranil Banik, Pavel Kroupa
The covariant scale-invariant dynamics (SID) theory has recently been proposed as a possible explanation for the observed dynamical discrepancies in galaxies (Maeder & Gueorguiev 2…
Effects of Lens Motion and Uneven Magnification on Image Spectra
Indranil Banik, Hongsheng Zhao
Counter to intuition, the images of an extended galaxy lensed by a moving galaxy cluster should have slightly different spectra in any metric gravity theory. This is mainly for two…
