The impact of nonlinear Landau damping on cosmic ray streaming and the role of external turbulence

Rouven Lemmerz, Mohamad Shalaby, Ellen Zweibel +2

Cosmic rays (CRs) streaming faster than the Alfvén speed generate Alfvén waves that scatter them. The saturated wave amplitude is regulated by a damping mechanism. This damping con…

CRexit observed: probing cosmic ray transport in the circumgalactic medium with absorption line spectra

Matthias Weber, Timon Thomas, Christoph Pfrommer +1

Cosmic rays (CRs) likely provide dynamically important non-thermal pressure support in the circumgalactic medium (CGM), but how their transport physics shapes observable absorption…

Effective cosmic ray diffusion in multiphase galactic environments

Timon Thomas, Christoph Pfrommer, Rüdiger Pakmor +2

Cosmic-ray (CR) feedback is widely recognized as a key regulator of galaxy formation. After being accelerated at supernova remnant shocks, CRs propagate through the interstellar me…

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…

CRexit: how different cosmic ray transport modes affect thermal instability in the circumgalactic medium

Matthias Weber, Timon Thomas, Christoph Pfrommer +1

The circumgalactic medium (CGM) plays a critical role in galaxy evolution, influencing gas flows, feedback processes, and galactic dynamics. Observations show a substantial cold ga…
