Abstract: We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodynamical simulations IllustrisTNG. In particular, we quantify environmental effects on satellite… read more here.

DOI: 10.1093/mnrasl/sly162
Abstract: NGC1052-DF2 was recently discovered as the dark-matter deficient galaxy claimed by van Dokkum et al. (2018a, vD18). However, large uncertainties on its dynamical mass estimate have been pointed out, concerning the paucity of sample, statistical… read more here.

DOI: 10.1103/physrevd.103.056025
Abstract: In this work, we study the relativistic quantum kinetic equations in $2+1$ dimensions from Wigner function formalism by carrying out a systematic semiclassical expansion up to $\ensuremath{\hbar}$ order. The derived equations allow us to explore… read more here.
