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 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…
The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters
Yuanyuan Zhao, Haiguang Xu, Ang Liu +8
Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…
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…
