Can bars erode cuspy halos?

Kataria, Sandeep Kumar; Mousumi Das (Cambridge University Press, 2019-06)

One of the major and widely known small scale problem with the Lambda CDM model of cosmology is the “core-cusp” problem. In this study we investigate whether this problem can be resolved using bar instabilities. We see ...
The Effect of Bulge Mass on Bar Pattern Speed in Disk Galaxies

Kataria, Sandeep Kumar; Mousumi Das (IOP Publishing, 2019-11)

We present a study of the effect of bulge mass on the evolution of bar pattern speed in isolated disk galaxies using N -body simulations. Earlier studies have shown that disk stars at the inner resonances can transfer a ...
How does the presence of bar affects the fueling of supermassive black holes? An IllustrisTNG100 perspective

Kataria, Sandeep Kumar; Vivek, M (Oxford University Press on behalf of Royal Astronomical Society, 2024-01)

We conducted a statistical study of black hole masses of barred and unbarred galaxies in the IllustrisTNG100 cosmological magnetohydrodynamical simulations. This work aims to understand the role of the bars in the growth ...
