CHEX-MATE: Turbulence in the intra-cluster medium from X-ray surface brightness fluctuations

S Dupourqué, N Clerc, E Pointecouteau… - Astronomy & …, 2024 - aanda.org
The intra-cluster medium is prone to turbulent motion that will contribute to the non-thermal
heating of the gas, complicating the use of galaxy clusters as cosmological probes. Indirect …

CHEX-MATE: Characterization of the intra-cluster medium temperature distribution

L Lovisari, S Ettori, E Rasia, M Gaspari… - Astronomy & …, 2024 - aanda.org

observed properties are then shaped by how baryons distribute and energy is diffused …

Shape and connectivity of groups and clusters: Effect of the dynamical state and accretion history

C Gouin, T Bonnaire, N Aghanim - Astronomy & Astrophysics, 2021 - aanda.org
Matter distribution around clusters is highly anisotropic because clusters are the nodes of
the cosmic web. The shape of the clusters and the number of filaments to which they are …
