I am a postdoctoral fellow in School of Physics and Astronomy at Cardiff University. Before moving to Cardiff I was a postdoctoral fellow at Michigan State university, US between July 2018 to June 2022. I completed my PhD from Indian Institute of Science Bangalore, India in 2018. My research is focussed on studying the impact of feedback processes (AGN and stellar feedback) in the evolution of galaxies, groups and clusters using numerical simulations.

3D image of the initial state of baryon density in a galaxy cluster with halo mass ~ 8x1.0e14 Msun. Baryons are in a hydrostatic equilibrium within the dark matter potential well.
Movie showing the baryon density snapshots (700 kpc x 700 kpc) of self consistent cold-mode kinetic AGN feedback simulation in a galaxy group (Halo mass - 1.0e13 Msun). The amount of cold gas falling with r < 0.5 kpc determines the jet power. AGN couples with the ICM inflates cavities, produces shocks and causes turbulence within the core lowering cooling rate. This in turn lowers the jet power. This cycle continues throughout the run time.
Movie showing the growth of thermal insability using temperature (in keV) snapshots. The simulation has been run with galaxy cluster initial conditions for the baryons with magnetic field, radiatiive cooling and anisotropic thermal conduction physics using PLUTO code. The arrows shows the local magnetic field unit vector. The non-linear stage starts at around 0.45 Gyr and the magnetic field lines no longer remain aligned at 45-degrees to the x-axis.
