Velocity Dispersions of Quiescent Galaxies in IllustirisTNG [PDF]
We examine the central stellar velocity dispersion of subhalos based on IllustrisTNG cosmological hydrodynamic simulations. The central velocity dispersion is a fundamental observable that links galaxies with their dark matter subhalos. We carefully explore simulated stellar velocity dispersions derived with different definitions to assess possible ...

Stellar Velocity Dispersion in Mergers: The Effects of Dust and Star Formation [PDF]
We investigate the effects of stellar evolution and dust on measurements of stellar velocity dispersion in mergers of disk galaxies. $N$-body simulations and radiative transfer analysis software are used to obtain mass-weighted and flux-weighted measurements of stellar velocity dispersion.

The Velocity Dispersion Function for Quiescent Galaxies in Massive Clusters from IllustrisTNG [PDF]
We derive the central stellar velocity dispersion function for quiescent galaxies in 280 massive clusters with $\log (M_{200} / M_{\odot}) > 14$ in IllustrisTNG300. The velocity dispersion function is an independent tracer of the dark matter mass distribution of subhalos in galaxy clusters. Based on the IllustrisTNG cluster catalog, we select quiescent

Velocity dispersions in statistical lensing
The theoretical average line-of-sight velocity dispersion along the radius of a spherical galaxy or cluster of galaxies tends to a variable value. Statistical lensing studies often take into account only the asymptotic value, either close to the center or at large distances, rather than the full variation: this results in significant effects in lensing
