Baryonification IV: Constraining baryonic feedback with X-ray gas fractions
Jozef Bucko, Andrina Nicola, Aurel Schneider +8
Baryonic feedback redistributes gas around dark matter halos, suppressing the matter power spectrum at scales now probed by weak lensing surveys. X-ray observations directly trace…
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…
Toward mapping turbulence in the intracluster medium III. Constraints on the turbulent power spectrum with Athena/X-IFU
Sophie Beaumont, Alexeï Molin, Nicolas Clerc +5
Context. Future X-ray observatories with high spectral resolution and imaging capabilities will enable measurements and mappings of emission line shifts in the intracluster medium…
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…
Observing gravitational redshift with X-Ray emission in galaxy clusters with Athena X-IFU
Alexeï Molin, Nicolas Clerc, Étienne Pointecouteau +2
Context. The Doppler shift predicted by general relativity for light escaping a gravitational potential has been observed on Earth as well as in the direction of various stars and…
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…
Towards mapping turbulence in the intra-cluster medium -- II. Measurement uncertainties in the estimation of structure functions
E. Cucchetti, N. Clerc, E. Pointecouteau +2
X-ray observations of the hot gas filling the intra-cluster medium provide a wealth of information on the dynamics of clusters of galaxies. The global equilibrium of the ICM is bel…
Measuring turbulence and gas motions in galaxy clusters via synthetic Athena X-IFU observations
M. Roncarelli, M. Gaspari, S. Ettori +7
The X-ray Integral Field Unit (X-IFU) that will be on board the Athena telescope will provide an unprecedented view of the intracluster medium (ICM) kinematics through the observat…
