The dust SED in the dwarf galaxy NGC 1569: Indications for an altered dust composition?

U. Lisenfeld, F. P. Israel, J. Stil +2

We discuss the interpretation of the dust SED from the mid-infrared to the millimeter range of NGC 1569. The model developed by Désert et al. (1990) including three dust component…

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…

Probing magnetic fields in the circumgalactic medium using polarization data from MIGHTEE

K. Böckmann, M. Brüggen, V. Heesen +10

The detection and study of magnetic fields surrounding galaxies is important to understand galaxy evolution since magnetic fields are tracers for dynamical processes in the circumg…

Comparison of algorithms for determination of rotation measure and Faraday structure I. 1100 - 1400 MHz

X. H. Sun, L. Rudnick, Takuya Akahori +14

(abridged) We run a Faraday structure determination data challenge to benchmark the currently available algorithms including Faraday synthesis (previously called RM synthesis in th…

Cygnus Loop: A double bubble?

J. West, S. Safi-Harb, I. Reichardt +4

The Cygnus Loop is a well-studied supernova remnant (SNR) that has been observed across the electromagnetic spectrum. Although widely believed to be an SNR shell with a blow- out r…

The HI/OH/Recombination line survey of the inner Milky Way (THOR)

H. Beuther, S. Bihr, M. Rugel +27

Context: The past decade has witnessed a large number of Galactic plane surveys at angular resolutions below 20". However, no comparable high-resolution survey exists at long radio…
