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)…
The low-frequency flattening of the radio spectrum of giant HII regions in M 101
L. Gajović, V. Heesen, M. Brüggen +10
In galaxies, the flattening of the spectrum at low radio frequencies below 300 MHz has been the subject of some debate. A turnover at low frequencies could be caused by multiple ph…
LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. II. Analysis
S. Piras, C. Horellou, J. Conway +7
Deep polarization surveys at low radio frequencies are key to cosmic magnetism studies: Larger catalogs of polarized extragalactic sources and increased precision on Faraday rotati…
Cosmo-tomography toward PKS1830-211: Variability of the quasar and of its foreground molecular absorption monitored with ALMA
S. Muller, I. Marti-Vidal, F. Combes +7
Time variability of astronomical sources provides crude information on their typical size and on the implied physical mechanisms. PKS1830-211 is a remarkable radio-bright lensed qu…
LOFAR Deep Fields: Probing faint Galactic polarised emission in ELAIS-N1
Iva Šnidarić, Vibor Jelić, Maaijke Mevius +13
We present the first deep polarimetric study of Galactic synchrotron emission at low radio frequencies. Our study is based on 21 observations of the European Large Area Infrared Sp…
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…
