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…
The quasi-adiabatic relaxation of haloes in the IllustrisTNG and EAGLE cosmological simulations
Premvijay Velmani, Aseem Paranjape
The dark matter content of a gravitationally bound halo is known to be affected by the galaxy and gas it hosts. We characterise this response for haloes spanning over four orders o…
The distribution of HI velocity profiles in a CDM universe
Aseem Paranjape, R. Srianand, Tirthankar Roy Choudhury +1
We model the distribution of the observed profiles of 21 cm line emission from neutral hydrogen (HI) in central galaxies selected from a statistically representative mock catalog o…
The radial acceleration relation in a CDM universe
Aseem Paranjape, Ravi K. Sheth
We study the radial acceleration relation (RAR) between the total () and baryonic () centripetal acceleration profiles of central galaxies in the cold da…
Multi-wavelength mock galaxy catalogs of the low-redshift Universe
Aseem Paranjape, Tirthankar Roy Choudhury, Ravi K. Sheth
We present a new suite of mock galaxy catalogs mimicking the low-redshift Universe, based on an updated halo occupation distribution (HOD) model and a scaling relation between opti…
Mass accretion rates and multi-scale halo environment in cold and warm dark matter cosmologies
Payaswinee Dhoke, Aseem Paranjape
We study the evolving environment dependence of mass accretion by dark haloes in simulations of cold and warm dark matter (CDM and WDM) cosmologies. The latter allows us to probe t…
