DISCOVERY AND COSMOLOGICAL IMPLICATIONS OF SPT-CL J2106-5844, THE MOST MASSIVE KNOWN CLUSTER AT z > 1 by Andersson, Karl, Bautz, Marshall W.

“…Using the South Pole Telescope (SPT), we have discovered the most massive known galaxy cluster at z>1, SPT-CL J2106-5844. In addition to producing a strong Sunyaev-Zel'dovich (SZ) effect signal, this system is a luminous X-ray source and its numerous constituent galaxies display spatial and color clustering, all indicating the presence of a massive galaxy cluster. …”

How AGN feedback and metal cooling shape cluster entropy profiles by Dubois, Y, Devriendt, J, Teyssier, R, Slyz, A

“…Using cosmological resimulations of a galaxy cluster, we study the evolution of its intracluster medium (ICM) gas properties, and through them we assess the effect of different (sub-grid) modelling of the physical processes at play, namely gas cooling, star formation, feedback from supernovae and active galactic nuclei (AGN). …”

Jet-regulated cooling catastrophe by Dubois, Y, Devriendt, J, Slyz, A, Teyssier, R

“…It also dramatically alters the shape of the gas density profile, bringing it in close agreement with the beta model favoured by observations, producing quite an isothermal galaxy cluster for gigayears in the process. However, it still falls short in matching the lower than Universal baryon fractions which seem to be commonplace in observed galaxy clusters.…”

How active galactic nucleus feedback and metal cooling shape cluster entropy profiles by Dubois, Y, Devriendt, J, Teyssier, R, Slyz, A

“…Using cosmological resimulations of a galaxy cluster, we study the evolution of its intracluster medium (ICM) gas properties, and through them we assess the effect of different (subgrid) modelling of the physical processes at play, namely gas cooling, star formation, feedback from supernovae and active galactic nuclei (AGNs). …”

Nonlinear growth of firehose and mirror fluctuations in astrophysical plasmas. by Schekochihin, A, Cowley, S, Kulsrud, R, Rosin, MS, Heinemann, T

“…In turbulent high-beta astrophysical plasmas (exemplified by the galaxy cluster plasmas), pressure-anisotropy-driven firehose and mirror fluctuations grow nonlinearly to large amplitudes, deltaB/B approximately 1, on a time scale comparable to the turnover time of the turbulent motions. …”

Gravitational lensing for a boosted Kerr black hole in the presence of plasma by Carlos A. Benavides-Gallego, A. A. Abdujabbarov, Cosimo Bambi

“…We also study the behavior of light in the presence of plasma by considering different distributions: singular isothermal sphere, non-singular isothermal gas sphere, and plasma in a galaxy cluster. We find that the dragging of the inertial system along with the boosted parameter $$\varLambda $$ Λ affect the value of the deflection angle. …”
