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…
Cosmic gas highways in C-EAGLE simulations
I. Vurm, J. Nevalainen, S. E. Hong +3
A substantial fraction of the cosmic baryons is expected to hide in the form of diffuse warm-hot intergalactic medium (WHIM), the majority of which resides in the filaments of the…
X-IFU/Athena view of the most distant galaxy clusters in the Universe
Florent Castellani, N. Clerc, Etienne Pointecouteau +2
The X-ray Integral Field Unit (X-IFU) on-board the second large ESA mission ''Athena'' will be a high spatial (5'') and spectral (2.5eV) resolution X-ray imaging spectrometer, oper…
The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
Andrew Robertson, Richard Massey, Vincent Eke +10
We present the first simulated galaxy clusters (M_200 > 10^14 Msun) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater diversity in both dar…
The Cluster-EAGLE project: velocity bias and the velocity dispersion - mass relation of cluster galaxies
Thomas Joshua Armitage, David. J. Barnes, Scott. T. Kay +4
We use the Cluster-EAGLE simulations to explore the velocity bias introduced when using galaxies, rather than dark matter particles, to estimate the velocity dispersion of a galaxy…
The XXL Survey IV. Mass-temperature relation of the bright cluster sample
Maggie Lieu, Graham P. Smith, Paul A. Giles +18
The XXL survey is the largest survey carried out by XMM-Newton. Covering an area of 50deg, the survey contains galaxy clusters out to a redshift 2 and to an X-r…
Mock weak lensing analysis of simulated galaxy clusters: bias and scatter in mass and concentration
Yannick M. Bahé, Ian G. McCarthy, Lindsay J. King
(Abridged) We quantify the bias and scatter in galaxy cluster masses and concentrations derived from an idealised mock weak gravitational lensing (WL) survey, and their effect on t…
