Non-spherical BUFFALOs: a weak lensing view of the Frontier Field clusters and associated systematics

A. Niemiec, A. Acebron, B. Beauchesne +15

Galaxy clusters are tracers of the large scale structures of the Universe, making the time evolution of their mass function dependent on key cosmological parameters, such as the co…

XGAP with uGMRT I: Old AGN plasma in merging galaxy groups

R. Santra, R. Kale, K. Kolokythas +10

Galaxy groups are affected by outflows from central Active Galactic Nuclei due to the shallower gravitational potential compared to galaxy clusters. The group binding energy is com…

CHEX-MATE: Relationship between X-ray and millimetre inferences of galaxy cluster temperature profiles

F. De Luca, H. Bourdin, P. Mazzotta +25

Thermodynamic profiles from X-ray and millimetre observations of galaxy clusters are often compared under the simplifying assumptions of smooth, spherically symmetric intracluster…

CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction

M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31

In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…

Extreme AGN feedback in the fossil galaxy group SDSSTG 4436

D. Eckert, F. Gastaldello, L. Lovisari +20

Supermassive black hole feedback is the currently favoured mechanism to regulate the star formation rate of galaxies and prevent the formation of ultra-massive galaxies ($M_\star>1…

Modelling the selection of galaxy groups with end to end simulations

R. Seppi, D. Eckert, A. Finoguenov +13

Feedback from supernovae and AGN shapes galaxy formation and evolution, yet its impact remains unclear. Galaxy groups offer a crucial probe, as their binding energy is comparable t…
