The topology of the magnetic field in Abell 2255 out to its virial radius. Results from the LOFAR Galaxy Cluster Ultra-Deep Field

A. Botteon, R. J. van Weeren, Y. Hu +14

We present the LOFAR Galaxy Cluster Ultra-Deep Field, in which 336 h of LOFAR observations at 120168 MHz have been collected on the nearby () cluster Abell 2255. This m…

Magnetic field morphological diagnostics with ALMA in the G327.29 protocluster: VGT versus dust polarization

A. Koley, A. M. Stutz, A. Lazarian +7

Magnetic fields and turbulence may play a key role in the evolution of protoclusters, influencing the formation of dense cores and stars. Here, we examine the morphology of the mag…

Model of super-Alfvénic MHD turbulence and structure functions of polarization

A. Lazarian, D. Pogosyan, Y. Hu

MHD turbulence driven at velocities higher than the Alfvén velocity, i.e., super-Alfvénic turbulence, is widely spread in astrophysical environments, including galaxy clusters and…
