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…

The X-ray Integral Field Unit at the end of the Athena reformulation phase

Philippe Peille, Didier Barret, Edoardo Cucchetti +279

The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…

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…

Constraining the origin and models of chemical enrichment in galaxy clusters using the Athena X-IFU

F. Mernier, E. Cucchetti, L. Tornatore +16

The chemical enrichment of the Universe at all scales is related to stellar winds and explosive supernovae phenomena. Metals produced by stars and later spread at the mega-parsec s…
