DOI: 10.1093/mnras/stab2933
Abstract: We present the first characterization of the circumgalactic medium of Lyα emitters (LAEs), using a sample of 96 z ≈ 3.3 LAEs detected with the VLT/MUSE in fields centered on 8 bright background quasars. The… read more here.

DOI: 10.1093/mnras/stac2390
Abstract: Motivated by integral field units (IFUs) on large ground telescopes and proposals for ultraviolet-sensitive space telescopes to probe circumgalactic medium (CGM) emission, we survey the most promising emission lines and how such observations can inform… read more here.

DOI: 10.1093/mnras/stad1195
Abstract: We study the impact of resonantly scattered X-ray line emission on the observability of the hot circumgalactic medium (CGM) of galaxies. We apply a Monte Carlo radiative transfer post-processing analysis to the high-resolution TNG50 cosmological… read more here.

DOI: 10.1093/mnras/stx2968
Abstract: Annihilating dark matter (DM) models offer promising avenues for future DM detection, in particular via modification of astrophysical signals. However when modelling such potential signals at high redshift the emergence of both dark matter and… read more here.

DOI: 10.1093/mnras/sty1283
Abstract: We characterize the properties of the intergalactic medium (IGM) around a sample of galaxies extracted from state-of-the-art hydrodynamical simulations of structure formation in a cosmological volume of 25 Mpc comoving at $z\sim 2$. The simulations… read more here.

DOI: 10.1093/mnras/stz1773
Abstract: We use a particle tracking analysis to study the origins of the circumgalactic medium (CGM), separating it into (1) accretion from the intergalactic medium (IGM), (2) wind from the central galaxy, and (3) gas ejected… read more here.

DOI: 10.1093/mnrasl/sly190
Abstract: The circumgalactic medium (CGM), i.e. the gaseous haloes around galaxies, is both the reservoir of gas that fuels galaxy growth and the repository of gas expelled by galactic winds. Most cosmological, hydrodynamical simulations focus their… read more here.
