CHANG-ES. XXXVIII. A Thin Radio Halo Shaped by Slow Cosmic-Ray Transport in the Quiescent Galaxy NGC 4565

Jianghui Xu, Jiang-Tao Li, Guilin Liu +11

We present the VLA C-array S-band (2--4 GHz) radio continuum observations of the nearby edge-on spiral galaxy NGC 4565, a target from the Continuum Halos in Nearby Galaxies - an EV…

Analytical Framework for Expanding Bubbles in a Hot Circumgalactic Medium

Jiang-Tao Li

We develop an analytic framework for the evolution of feedback-driven bubbles expanding into a hot, volume-filling circumgalactic medium (CGM), where the ambient pressure and sound…

Cosmic-ray electron propagation in NGC 3044 from radio continuum observations

Shengtao Wang, Xiaohui Sun, George Heald +5

Star-forming edge-on galaxies often exhibit extended halo radiation in multiple bands, providing ideal laboratories for studying the transfer of matter from the disk to the halo. W…

Simulating the Formation of the Young "Fermi Bubbles" in the Circinus Galaxy

Shaokun Xie, Fulai Guo, Ruiyu Zhang +3

The Fermi and eROSITA bubbles in the Milky Way represent an archetypal case of galactic nucleus feedback, yet their origin remains highly debated. Here we use hydrodynamic simulati…

On the baryon budget in the X-ray-emitting circumgalactic medium of Milky Way-mass galaxies

Yi Zhang, Soumya Shreeram, Gabriele Ponti +6

Recent observations with SRG/eROSITA have revealed the average X-ray surface brightness profile of the X-ray-emitting circumgalactic medium (CGM) around Milky Way (MW)-mass galaxie…
