72. Particle acceleration and non-thermal emission from galaxy clusters and large scale structure

Gianfranco Brunetti

8/19/22, 9:00 AM

Cluster scale radio emission traces relativistic particles and magnetic fields in the ICM, the origin of these non-thermal components is a long-standing problem. More recent observations with LOFAR have revealed synchrotron emission extending beyond the central, Mpc, regions of galaxy clusters, in cluster outskirts or in cosmic filaments that connect pairs of massive clusters.

96. Radio relics and their substructure (via Zoom)

81. Thermal Instability with Cosmic Ray Heating

Tsun Hin Navin Tsung (University of California, Santa Barbara)

8/19/22, 9:50 AM

Observations have revealed clusters having high core densities; the cooling times of these clusters are much less than the Hubble time and should result in cooling flows, which were not seen. This means there is global heating supporting clusters from the cooling catastrophe. On the other hand, H-alpha observations have shown that despite being in global thermal equilibrium, cold gas do exist...

88. Cosmological zoom simulations of merging galaxy clusters

65. Co-Evolution of Cosmic Rays and Thermal Plasma in Galaxy Clusters

Ellen Zweibel (U Wisconsin-Madison)

Macroscale magnetized turbulence, acting jointly with microscale kinetic turbulence, can heat weakly collisional, high beta plasmas such as the ICM through a process known as magnetic pumping. This talk, which is complementary to a presentation by Francisco Ley, will discuss two effects and their relevance to energy balance in the ICM: enhancement of the heating rate in the presence of...

87. Non-thermal pressure, cosmic rays/non-thermal particles, and radio halos

Eugene Churazov (MPA)
