The origin of scatter in the X-ray luminosity - halo mass relation of galaxy clusters
Joey Braspenning, Joop Schaye, Annalisa Pillepich +1
Galaxy groups and clusters are excellent probes of large-scale structure and are shaped by some of the most energetic physical processes in the Universe. They follow a tight scalin…

Mass Proxy Quality of Massive Halo Properties in the IllustrisTNG and FLAMINGO Simulations: I. Hot Gas
Eddie Aljamal, August E. Evrard, Arya Farahi +5
We examine scale and redshift dependence of mass-property relations (MPRs) for five hot gas properties of two large group- and cluster-scale halo samples realized by the IllustrisT…

Characterising galaxy cluster scaling relations as cosmic isotropy tracers using FLAMINGO simulations
Yujie He, Konstantinos Migkas, Joop Schaye +2
The standard cosmological model, CDM, assumes isotropy on large cosmic scales. However, recent studies using galaxy cluster scaling relations have reported an apparent ani…
