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…
Impact of the large-scale cosmic web on the X-ray emitting circumgalactic medium
Soumya Shreeram, Daniela Galárraga-Espinosa, Johan Comparat +9
The hot circumgalactic medium (CGM), probed by X-ray observations, plays a central role in understanding gas flows that drive a galaxy's evolution. While CGM properties have been w…
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-…
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…
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…
