A case study of early galaxy cluster with the Athena X-IFU
F. Castellani, N. Clerc, E. Pointecouteau +3
Context: Observations of the hot gas in distant clusters of galaxies, though challenging, are key to understand the role of intense galaxy activity, super-massive black hole feedba…
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…
