CHANG-ES XL: Magnetic Field Structures in the Disk and Halo of NGC 891

N. Pourjafari, J. M. Stil, R. -J. Dettmar +11

We present new Karl G. Jansky Very Large Array S-band (2-4 GHz) observations of the edge-on spiral galaxy NGC 891, complemented by C-band data, to investigate the structure of its…

Probing Magnetic Fields In and Around Galaxies Near and Far

S. A. Mao, Rainer Beck, Aritra Basu +14

In order to understand the magnetization of galaxies and the role of magnetic fields in feedback processes that govern star formation and galaxy evolution, it is essential to have…

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…

CHANG-ES XXXVII. Effects of spectral aging on radio scale heights

D. C. Smolinski, V. Heesen, M. Brüggen +7

Context. Cosmic rays and magnetic fields play an important role for the formation and evolution of galaxies. Radio continuum observations allows us to study them in the haloes of e…

CHANG-ES: XXXVI. The thin and thick radio discs

V. Heesen, M. Stein, N. Pourjafari +8

Context. Edge-on spiral galaxies give us an outsiders' view of the radio halo, which envelops these galaxies. The radio halos are caused by extra-planar cosmic-ray electrons that e…
