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…
Matter power spectrum and the challenge of percent accuracy
Aurel Schneider, Romain Teyssier, Doug Potter +7
Future galaxy surveys require one percent precision in the theoretical knowledge of the power spectrum over a large range including very nonlinear scales. While this level of accur…
The same with less: The cosmic web of warm versus cold dark matter dwarf galaxies
Darren S. Reed, Aurel Schneider, Robert E. Smith +3
We explore fundamental properties of the distribution of low mass dark matter halos within the cosmic web using warm dark matter (WDM) and cold dark matter (CDM) cosmological simul…
Halo Mass Function and the Free Streaming Scale
Aurel Schneider, Robert E. Smith, Darren Reed
The nature of structure formation around the particle free streaming scale is still far from understood. Many attempts to simulate hot, warm, and cold dark matter cosmologies with…
Precision cosmology in muddy waters: Cosmological constraints and N-body codes
Robert E. Smith, Darren S. Reed, Doug Potter +3
Future large-scale structure surveys of the Universe will aim to constrain the cosmological model and the true nature of dark energy with unprecedented accuracy. In order for these…
