[HTML][HTML] Baryon cycles in the biggest galaxies
The universe's biggest galaxies have both vast atmospheres and supermassive central
black holes. This article reviews how those two components of a large galaxy couple and …

The galaxy cluster mass scale and its impact on cosmological constraints from the cluster population
The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

Cosmological constraints from galaxy clusters and groups in the eROSITA final equatorial depth survey
We present the first cosmological study of a sample of eROSITA clusters, which were
identified in the eROSITA Final Equatorial Depth Survey (eFEDS). In a joint selection on X …

Feedback from active galactic nuclei in galaxy groups
The co-evolution between supermassive black holes and their environment is most directly
traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere …

Modelling baryonic feedback for survey cosmology
Observational cosmology in the next decade will rely on probes of the distribution of matter
in the redshift range between $0< z< 3$ to elucidate the nature of dark matter and dark …

Cluster cosmology constraints from the 2500 deg2 SPT-SZ survey: inclusion of weak gravitational lensing data from Magellan and the Hubble space telescope
We derive cosmological constraints using a galaxy cluster sample selected from the 2500
deg 2 SPT-SZ survey. The sample spans the redshift range 0.25< z< 1.75 and contains 343 …

Non-thermal pressure support in X-COP galaxy clusters
Galaxy clusters are the endpoints of structure formation and are continuously growing
through the merging and accretion of smaller structures. Numerical simulations predict that a …
