Planck Constraints on Turbulence in the Coma Cluster
Baptiste Sigal, Etienne Pointecouteau, Nicolas Clerc +6
Turbulence within the intracluster medium (ICM) influences galaxy cluster thermodynamics and virialisation, contributing to non-thermal pressure support and impacting hydrostatic m…
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…
Toward mapping turbulence in the intracluster medium IV. Using NewAthena/X-IFU and simulation based inference to constrain turbulence
Alexeï Molin, Simon Dupourqué, Nicolas Clerc +3
Context. The NewAthena mission planned for launch in the late 2030s will carry X-IFU, an integral field unit spectrometer that will obtain unique insight into the X-ray hot univers…
PITSZI: Probing Intra-cluster medium Turbulence with Sunyaev-Zel'dovich Imaging -- Application to the triple merging cluster MACS J0717.5+3745
R. Adam, T. Eynard-Machet, I. Bartalucci +8
Turbulent gas motions are expected to dominate the non-thermal energy budget of the intracluster medium (ICM). The measurement of pressure fluctuations from high angular resolution…
CHEX-MATE : turbulence in the ICM from X-ray surface brightness fluctuations
Simon Dupourqué, Nicolas Clerc, Etienne Pointecouteau +15
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. In…
Investigating the turbulent hot gas in X-COP galaxy clusters
Simon Dupourqué, Nicolas Clerc, Etienne Pointecouteau +3
Turbulent processes at work in the intracluster medium perturb this environment, displacing gas, and creating local density fluctuations that can be quantified via X-ray surface br…
Characterizing the bulk and turbulent gas motions in galaxy clusters
Simon Dupourqué, Etienne Pointecouteau, Nicolas Clerc +1
The most massive halos of matter in the Universe grow via accretion and merger events throughout cosmic times. These violent processes generate shocks at many scales and induce lar…
