LOFAR MSSS: Flattening low-frequency radio continuum spectra of nearby galaxies
(2018-11-07)
Aims. 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 shaping them. In this work we take ...
Polarized point sources in the LOFAR Two-meter Sky Survey: A preliminary catalog
(2018-06-01)
The polarization properties of radio sources at very low frequencies (<200 MHz) have not been widely measured, but the new generation of low-frequency radio telescopes, including the Low Frequency Array (LOFAR: a Square ...
