Entropy plateaus can emerge from gas replacement at a characteristic halo mass in simulated groups and clusters of galaxies

Edoardo Altamura, Scott T. Kay, Joop Schaye +2

The evolution of the intergalactic medium (IGM) is influenced by gravitational collapse, radiative cooling, and baryonic feedback. Using cosmological hydrodynamic zoom-in simulatio…

Hydrostatic mass bias for galaxy groups and clusters in the FLAMINGO simulations

Joey Braspenning, Joop Schaye, Matthieu Schaller +2

The masses of galaxy clusters are commonly measured from X-ray observations under the assumption of hydrostatic equilibrium (HSE). This technique is known to underestimate the true…

Relativistic SZ temperatures and hydrostatic mass bias for massive clusters in the FLAMINGO simulations

Scott T. Kay, Joey Braspenning, Jens Chluba +4

The relativistic Sunyaev-Zel'dovich (SZ) effect can be used to measure intracluster gas temperatures independently of X-ray spectroscopy. Here, we use the large-volume FLAMINGO sim…

The FLAMINGO Project: Galaxy clusters in comparison to X-ray observations

Joey Braspenning, Joop Schaye, Matthieu Schaller +10

Galaxy clusters are important probes for both cosmology and galaxy formation physics. We test the cosmological, hydrodynamical FLAMINGO simulations by comparing to observations of…

Inferring the dark matter splashback radius from cluster gas and observable profiles in the FLAMINGO simulations

Imogen Towler, Scott T. Kay, Joop Schaye +10

The splashback radius, coinciding with the minimum in the dark matter radial density gradient, is thought to be a universal definition of the edge of a dark matter halo. Observatio…

CHEX-MATE: CLUster Multi-Probes in Three Dimensions (CLUMP-3D), I. Gas Analysis Method using X-ray and Sunyaev-Zel'dovich Effect Data

Junhan Kim, Jack Sayers, Mauro Sereno +23

Galaxy clusters are the products of structure formation through myriad physical processes that affect their growth and evolution throughout cosmic history. As a result, the matter…
