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…
CHANG-ES XXXIX. Magnetic field structure in edge-on galaxies: Stacking Stokes parameters
M. Stein, R. Beck, B. Adebahr +12
Galactic magnetic fields regulate star formation and cosmic-ray (CR) transport, and understanding their three-dimensional structure, particularly in star-forming late-type galaxies…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
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…
Magnetohydrodynamic turbulence and the associated spatial diffusion tensor of cosmic rays in dynamical galactic halos
J. Kleimann, H. Fichtner, M. Stein +3
A detailed understanding of cosmic-ray transport in galactic halos is essential for explaining various observations, such as the radio continuum measurements of synchrotron radiati…
CHANG-ES XXXIV: Magnetic Field Structure in Edge-On Galaxies Characterising large-scale magnetic fields in galactic halos
M. Stein, J. Kleimann, B. Adebahr +12
Understanding galactic magnetic fields is essential for interpreting feedback processes in galaxies. Despite their importance, the exact structure of these fields, particularly in…
CHANG-ES XXXIV: a 20 kpc radio bubble in the halo of the star-forming galaxy NGC 4217
V. Heesen, T. Wiegert, J. Irwin +11
Cosmic rays may be dynamically very important in driving large-scale galactic winds. Edge-on galaxies give us an outsider's view of the radio halo, which shows the presence of extr…
A spatially resolved radio spectral study of the galaxy M 51
L. Gajović, B. Adebahr, A. Basu +14
Radio continuum emission from galaxies at gigahertz frequencies can be used as an extinction-free tracer of star formation. However, at frequencies of a few hundred megahertz, ther…
A Collection of German Science Interests in the Next Generation Very Large Array
M. Kadler, D. A. Riechers, J. Agarwal +88
The Next Generation Very Large Array (ngVLA) is a planned radio interferometer providing unprecedented sensitivity at wavelengths between 21 cm and 3 mm. Its 263 antenna element ar…
Nearby galaxies in the LOFAR Two-metre Sky Survey III. Influence of cosmic-ray transport on the radio-SFR relation
V. Heesen, S. Schulz, M. Brüggen +7
Context. In order to understand galaxy evolution, it is essential to measure star formation rates (SFRs) across Cosmic times. Aims. The use of radio continuum emission as an extinc…
Detection of magnetic fields in the circumgalactic medium of nearby galaxies using Faraday rotation
V. Heesen, S. P. O'Sullivan, M. Brüggen +15
Context. The existence of magnetic fields in the circumgalactic medium (CGM) is largely unconstrained. Their detection is important as magnetic fields can have a significant impact…
Diffusion of cosmic-ray electrons in M 51 observed with LOFAR at 54 MHz
V. Heesen, F. de Gasperin, S. Schulz +8
Context. The details of cosmic-ray transport have a strong impact on galaxy evolution. The peak of the cosmic-ray energy distribution is observable in the radio continuum using the…
CHANG-ES XXVI: Insights into cosmic-ray transport from radio halos in edge-on galaxies
M. Stein, V. Heesen, R. -J. Dettmar +13
Galactic winds play a key role in regulating the evolution of galaxies over cosmic time. In recent years, the role of cosmic rays (CR) in the formation of the galactic wind has inc…
Nearby galaxies in the LOFAR Two-metre Sky Survey II. The magnetic field-gas relation
V. Heesen, T. -L. Klocke, M. Brüggen +8
Context. Magnetic fields are key to understand galaxy evolution, regulating stellar feedback and star formation in galaxies. Aims. We probe the origin of magnetic fields in late-ty…
