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…
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…
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…
