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…
Ultra-relativistic oscillon collisions
Mustafa A. Amin, Indranil Banik, Carina Nagreanu +1
In this short note we investigate the ultra-relativistic collisions of small amplitude oscillons in 1+1 dimensions. Using the amplitude of the oscillons and the inverse relativisti…
Galactic Archaeology with RAVE: Clues to the Formation of the Thick Disk
Indranil Banik
I present an analysis of ~13000 stars from RAVE Data Release 4 (DR4) to better understand the formation of the thick disk. The stars I consider are mostly within 1 kpc of the Sun.…
