On the generation of astrophysically-relevant intermittent magnetic turbulence in the laboratory
Itamar Cohen, Weipeng Yao, Archie F. A. Bott +18
Intermittent magnetic turbulence, namely the presence of non-ordered and clusterized fields, is a ubiquitous phenomenon in space and astrophysical plasmas. It is currently understo…
Disentangling AGN Feedback and Sloshing in the Perseus Cluster with XRISM: Insights from Simulations
Elena Bellomi, John A. ZuHone, Nhut Truong +10
High-resolution X-ray spectroscopy with XRISM has revealed complex, non-monotonic velocity dispersion profiles in the Perseus cluster, pointing to a complex interplay between at le…
Particle Acceleration in Magnetized Shear-Driven Turbulence
Mingxuan Liu, Mateusz Ruszkowski, Ellen Zweibel +5
Shear flows, ubiquitous in space and astrophysical plasmas, can accelerate particles through turbulence excited by the Kelvin-Helmholtz instability. We present the first numerical…
Resolving Star Cluster Formation in Galaxy Simulations with Cosmic Ray Feedback
Brandon Sike, Mateusz Ruszkowski, Oleg Y. Gnedin +4
Star clusters host the massive stars responsible for feedback in star-forming galaxies. Stellar feedback shapes the interstellar medium (ISM), affecting the formation of future sta…
Robust magnetic field estimates in star-forming galaxies with the equipartition formula in the absence of equipartition
H. -H. Sandy Chiu, Mateusz Ruszkowski, Maria Werhahn +2
The equipartition model is widely used to estimate magnetic field strength from synchrotron intensity in radio galaxies, yet the validity of its underlying assumptions remains unce…
Magnetic fields in the intracluster medium with TNG-Cluster: properties, morphology, and tangential anisotropy
Katrin Lehle, Mateusz Ruszkowski, Dylan Nelson +2
We characterize the magnetic field properties of 352 massive galaxy clusters from the TNG-Cluster magnetohydrodynamical cosmological simulation with a focus on central magnetic fie…
The Fermi Bubbles: Gamma-ray, Microwave, and Polarization Signatures of Leptonic AGN Jets
H. -Y. K. Yang, M. Ruszkowski, E. Zweibel
The origin of the Fermi bubbles and the microwave haze is yet to be determined. To disentangle different models requires detailed comparisons between theoretical predictions and mu…
The Fermi Bubbles: Supersonic AGN Jets with Anisotropic Cosmic Ray Diffusion
H. -Y. K. Yang, M. Ruszkowski, P. M. Ricker +2
The Fermi Gamma-ray Space Telescope reveals two large bubbles in the Galaxy, which extend nearly symmetrically ~50 degrees above and below the Galactic center (GC). Using three-dim…
Are black holes big enough to quench cooling in cluster cool cores?
M. Ruszkowski
Total energy arguments (e.g., Fabian et al. 2002) suggest that black holes need to have masses significantly in excess of the prediction from the classic black hole mass - velocity…
AGN heating, thermal conduction and Sunyaev-Zeldovich effect in galaxy groups and clusters
S. Roychowdhury, M. Ruszkowski, B. B. Nath
(abridged) We investigate in detail the role of active galactic nuclei on the physical state of the gas in galaxy groups and clusters, and the implications for anisotropy in the CM…
Heating, conduction and minimum temperatures in cooling flows
Mateusz Ruszkowski, Mitchell C. Begelman
There is mounting observational evidence from Chandra for strong interaction between keV gas and AGN in cooling flows. It is now widely accepted that the temperatures of cluster co…
Circular polarization from stochastic synchrotron sources
Mateusz Ruszkowski, Mitchell C. Begelman
The transfer of polarized radiation in stochastic synchrotron sources is explored by means of analytic treatment and Monte Carlo simulations. We argue that the main mechanism respo…
