The central cusps in dark matter halos: fact or fiction?
A. N. Baushev, S. V. Pilipenko
We investigate the reliability of standard N-body simulations by modelling of the well-known Hernquist halo with the help of \texttt{GADGET-2} code (which uses the tree algorithm t…
Why does Einasto profile index occur so frequently?
Anton N. Baushev, Maxim V. Barkov
We consider the behavior of spherically symmetric Einasto halos composed of gravitating particles in the Fokker-Planck approximation. This approach allows us to consider the undesi…
Galaxy collisions as a mechanism of ultra diffuse galaxy (UDG) formation
Anton N. Baushev
We suggest a possible mechanism of ultra diffuse galaxy formation: the UDGs may occur as a result of a central collision of galaxies. If the galaxies are young and contain a lot of…
Cusps in the center of galaxies: a real conflict with observations or a numerical artefact of cosmological simulations?
A. N. Baushev, L. del Valle, L. E. Campusano +3
Galaxy observations and N-body cosmological simulations produce conflicting dark matter halo density profiles for galaxy central regions. While simulations suggest a cuspy and univ…
