The evolving role of astrophysical modelling in dark matter halo relaxation response
Premvijay Velmani, Aseem Paranjape
We study the change in the radial distribution of dark matter within haloes in response to baryonic astrophysical processes in galaxies at different epochs, investigating the role…

Dynamics of the response of dark matter halo to galaxy evolution in IllustrisTNG
Premvijay Velmani, Aseem Paranjape
We present the dynamical evolution of the dark matter's relaxation response to galaxies and their connection to the astrophysical properties as simulated in the IllustrisTNG suite…

A self-similar model of galaxy formation and dark halo relaxation
Premvijay Velmani, Aseem Paranjape
We develop a spherical self-similar model for the formation of a galaxy through gas collapsing in an isolated self-gravitating dark matter halo. We improve upon the existing litera…
