The physics of galaxy cluster outskirts

S Walker, A Simionescu, D Nagai, N Okabe… - Space Science …, 2019 - Springer
As the largest virialized structures in the universe, galaxy clusters continue to grow and
accrete matter from the cosmic web. Due to the low gas density in the outskirts of clusters …

Outskirts of galaxy clusters

TH Reiprich, K Basu, S Ettori, H Israel, L Lovisari… - Space Science …, 2013 - Springer
Until recently, only about 10% of the total intracluster gas volume had been studied with high
accuracy, leaving a vast region essentially unexplored. This is now changing and a wide …

Universal thermodynamic properties of the intracluster medium over two decades in radius in the X-COP sample

V Ghirardini, D Eckert, S Ettori, E Pointecouteau… - Astronomy & …, 2019 - aanda.org
Context. The hot plasma in a galaxy cluster is expected to be heated to high temperatures

Feedback processes from baryons are expected to strongly affect weak-lensing observables
of current and future cosmological surveys. In this paper we present a new parametrisation …

The cool-core state of Planck SZ-selected clusters versus X-ray-selected samples: evidence for cool-core bias

M Rossetti, F Gastaldello, D Eckert… - Monthly Notices of …, 2017 - academic.oup.com

The XXL Survey-XIII. Baryon content of the bright cluster sample

D Eckert, S Ettori, J Coupon, F Gastaldello… - Astronomy & …, 2016 - aanda.org
Traditionally, galaxy clusters have been expected to retain all the material accreted since
their formation epoch. For this reason, their matter content should be representative of the …
