The XXL survey. XLIX. Linking the members star formation histories to the cluster mass assembly in the z = 1.98 galaxy cluster XLSSC 122 Open
The most massive protoclusters virialize to become clusters at z ∼ 2, which is also a critical epoch for the evolution of their member galaxies. XLSSC 122 is a z = 1.98 galaxy cluster with 37 spectroscopically confirmed members. We aim to …

Quiescent galaxies in a virialized cluster at redshift 2: evidence for accelerated size growth Open
We present an analysis of the galaxy population in XLSSC 122, an X-ray-selected, virialized cluster at redshift z = 1.98. We utilize Hubble Space Telescope (HST)Wide Field Camera 3 (WFC3) photometry to characterize the activity and morphol…

Revealing the star formation history of a mature galaxy cluster at z=2 Open
At z=1.98, XLSSC 122 is a massive and mature galaxy cluster with 37 spectroscopically confirmed members. We employ12 band PSF-matched photometry and BAGPIPES SED modelling to investigate the star formation histories, stellar mass, dust and…

The environmental dependence of X-ray AGN activity at <i>z</i> ∼ 0.4 Open
We present an analysis of the X-ray active galactic nucleus (AGN) population in a sample of seven massive galaxy clusters in the redshift range 0.35 < z < 0.45. We utilize high-quality Chandra X-ray imaging to robustly identify AGN a…

Galaxy populations in the most distant SPT-SZ clusters - I. Environmental quenching in massive clusters at 1.4 ≲ z ≲ 1.7 Open
© 2019 ESO. We present the first results from a galaxy population study in the highest redshift galaxy clusters identified in the 2500 deg 2 South Pole Telescope Sunyaev Zel'dovich effect (SPT-SZ) survey, which is sensitive to M 500 ≳ 3 × …
