The Faraday Rotation Measure Grid of the LOFAR Two-metre Sky Survey: Data Release 2
S. P. O'Sullivan, T. W. Shimwell, M. J. Hardcastle +24
A Faraday rotation measure (RM) catalogue, or RM Grid, is a valuable resource for the study of cosmic magnetism. Using the second data release (DR2) from the LOFAR Two-metre Sky Su…
CHANG-ES XXIII: Influence of a galactic wind in NGC 5775
G. H. Heald, V. Heesen, S. S. Sridhar +22
We present new radio continuum images of the edge-on starburst galaxy NGC 5775, from LOFAR (140 MHz) and the Karl G. Jansky Very Large Array CHANG-ES survey (1500 MHz). We trace th…
Nearby galaxies in LoTSS-DR2: insights into the non-linearity of the radio-SFR relation
V. Heesen, M. Staffehl, A. Basu +24
Context. Cosmic rays and magnetic fields are key ingredients in galaxy evolution, regulating both stellar feedback and star formation. Their properties can be studied with low-freq…
LOFAR MSSS: Flattening low-frequency radio continuum spectra of nearby galaxies
K. T. Chyży, W. Jurusik, J. Piotrowska +35
The shape of low-frequency radio continuum spectra of normal galaxies is not well understood, the key question being the role of physical processes such as thermal absorption in sh…
A spatially resolved radio spectral study of the galaxy M 51
L. GajoviÄ, 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…
The Application of Ridgelines in Extended Radio Source Cross-Identification
B. Barkus, J. H. Croston, J. Piotrowska +8
Extended radio sources are an important minority population in modern deep radio surveys, because they enable detailed investigation of the physics governing radio-emitting regions…
