A low frequency study of linear polarization in radio galaxies
Vijay H. Mahatma, Martin J. Hardcastle, Jeremy Harwood +4
Radio galaxies are linearly polarized -- an important property that allows us to infer the properties of the magnetic field of the source and its environment. However at low freque…
LOFAR Deep Fields: Probing a broader population of polarized radio galaxies in ELAIS-N1
N. Herrera Ruiz, S. P. O'Sullivan, V. Vacca +19
We present deep polarimetric observations of the European Large Area ISO Survey-North 1 (ELAIS-N1) field using the Low Frequency Array (LOFAR) at 114.9-177.4 MHz. The ELAIS-N1 fiel…
Cassiopeia A, Cygnus A, Taurus A, and Virgo A at ultra-low radio frequencies
F. de Gasperin, J. Vink, J. P. McKean +49
The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are ca…
New constraints on the magnetization of the cosmic web using LOFAR Faraday rotation observations
S. P. O'Sullivan, M. Brüggen, F. Vazza +11
Measuring the properties of extragalactic magnetic fields through the effect of Faraday rotation provides a means to understand the origin and evolution of cosmic magnetism. Here w…
