Origin of reduced dynamical friction by dark matter halos with net prograde rotation
Rimpei Chiba, Sandeep Kumar Kataria
We provide an explanation for the reduced dynamical friction on galactic bars in spinning dark matter halos. Earlier work based on linear theory predicted an increase in dynamical…
How does the presence of bar affects the fueling of supermassive black holes ? An IllustrisTNG100 perspective
Sandeep Kumar Kataria, M. Vivek
We conduct a statistical study of black hole masses of barred and unbarred galaxies in the IllustrisTNG100 cosmological magneto-hydrodynamical simulations. This work aims to unders…
Dark Matter Halo Spin of the Dwarf Galaxy UGC 5288: Insights from Observations, N-body and Cosmological Simulations
Sioree Ansar, Sandeep K Kataria, Mousumi Das
Dark matter (DM) halo angular momentum is very challenging to determine from observations of galaxies. In this study, we present a new hybrid method of estimating the dimensionless…
Modelling Dark Matter Halo Spin using Observations and Simulations: application to UGC 5288
Sioree Ansar, Sandeep Kumar Kataria, Mousumi Das
Dark matter (DM) halo properties are extensively studied in cosmological simulations but are very challenging to estimate from observations. The DM halo density profile of observed…
