Circumgalactic medium depletion drives satellite quenching in IllustrisTNG

Natan de Isídio, Natan de Isídio, Paola Popesso +6

Satellite galaxies dominate the quenched population at low stellar masses (), yet identifying which processes shut down their star formation,…

Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day

Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10

Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…

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…

Retrieving the hot circumgalactic medium physics from the X-ray radial profile from eROSITA with an IlustrisTNG-based forward model

Soumya Shreeram, Johan Comparat, Andrea Merloni +9

Recent eROSITA measurements of the radial profiles of the hot CGM in the Milky-Way stellar mass (MW-mass) regime provide us with a new benchmark to constrain the hot gas around MW-…

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…

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…
