What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba
D. T. Mazengo, P. Popesso, I. Marini +20
Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…
On the baryon budget in the X-ray-emitting circumgalactic medium of Milky Way-mass galaxies
Yi Zhang, Soumya Shreeram, Gabriele Ponti +6
Recent observations with SRG/eROSITA have revealed the average X-ray surface brightness profile of the X-ray-emitting circumgalactic medium (CGM) around Milky Way (MW)-mass galaxie…
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…
The hot circumgalactic medium in stacked X-rays: observations vs simulations
Skylar Grayson, Evan Scannapieco, Johan Comparat +5
Current cosmological simulations rely on active galactic nuclei (AGN) feedback to quench star formation and match observed stellar mass distributions, but models for AGN feedback a…
Cross-correlation between soft X-rays and galaxies A new benchmark for galaxy evolution models
Johan Comparat, Andrea Merloni, Gabriele Ponti +11
This article presents the construction and validation of complete stellar mass-selected, volume-limited galaxy samples using the Legacy Survey (data release 10) galaxy catalogs, co…
The impact of assembly history on the X-ray detectability of halos. From galaxy groups to galaxy clusters
I. Marini, P. Popesso, K. Dolag +15
Galaxy groups represent a significant fraction of the halo population, playing a crucial role in galaxy formation and evolution. However, their detection in X-rays remains challeng…
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…
The hot circumgalactic medium in the eROSITA All-Sky Survey I. X-ray surface brightness profiles
Yi Zhang, Johan Comparat, Gabriele Ponti +17
The circumgalactic medium (CGM) provides the material needed for galaxy formation and influences galaxy evolution. The hot () CGM is poorly detected around galaxies with s…
