Circumgalactic medium depletion drives satellite quenching in IllustrisTNG
Natan de Isídio, Paola Popesso, Sandro Tacchella +5
Satellite galaxies dominate the quenched population at low stellar masses (), yet identifying which processes shut down their star formation,…
The stellar-to-halo mass relation of central galaxies across three orders of halo mass
Victoria Toptun, Paola Popesso, Ilaria Marini +9
The stellar content of galaxies is tightly connected to the mass and growth of their host dark matter halos. Observational constraints on this relation remain limited, particularly…
Evolution of the Physical Properties of the Most Massive Galaxies in Clusters and their Protohalos
Qingyang Li, Xiaohu Yang, Antonios Katsianis +7
We investigated the evolution of the physical properties of the brightest galaxies in clusters and their protohalos from to . Galaxy clusters and groups are identifi…
The hot circumgalactic medium in the eROSITA All-Sky Survey III. Star-forming and quiescent galaxies
Yi Zhang, Johan Comparat, Gabriele Ponti +17
The circumgalactic medium (CGM), as the gas repository for star formation, might contain the answer to the mysterious galaxy quenching and bimodal galaxy population origin. We meas…
Quantifying Observational Projection Effects with a Simulation-based hot CGM model
Soumya Shreeram, Johan Comparat, Andrea Merloni +11
The hot phase of the circumgalactic medium (CGM) allows us to probe the inflow and outflow of gas within a galaxy, which is responsible for dictating the evolution of the galaxy. S…
The hot circumgalactic medium in the eROSITA All-Sky Survey II. Scaling relations between X-ray luminosity and galaxies' mass
Yi Zhang, Johan Comparat, Gabriele Ponti +16
Understanding how the properties of galaxies relate to the properties of the hot circum-galactic medium (CGM) around them can constrain galaxy evolution models. We measured the X-r…
