Hints against the cold and collisionless nature of dark matter from the galaxy velocity function
Aurel Schneider, Sebastian Trujillo-Gomez, Emmanouil Papastergis +2
The observed number of dwarf galaxies as a function of rotation velocity is significantly smaller than predicted by the standard model of cosmology. This discrepancy cannot be simp…
Another baryon miracle? Testing solutions to the "missing dwarfs" problem
Sebastian Trujillo-Gomez, Aurel Schneider, Emmanouil Papastergis +2
The dearth of dwarf galaxies in the local universe is hard to reconcile with the large number of low mass haloes expected within the concordance CDM paradigm. In this paper we p…
An accurate measurement of the baryonic Tully-Fisher relation with heavily gas-dominated ALFALFA galaxies
E. Papastergis, E. A. K. Adams, J. M. van der Hulst
We use a sample of 97 galaxies selected from the ALFALFA 21cm survey to make an accurate measurement of the baryonic Tully-Fisher relation (BTFR). These galaxies are specifically s…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
