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…
