Duty cycle of the radio galaxy B2 0258+35
(2018-10-11)
Context. Radio loud active galactic nuclei (AGN) are episodic in nature, cycling through periods of activity and quiescence. The study of this duty cycle has recently gained new relevance because of the importance of AGN ...
The intergalactic magnetic field probed by a giant radio galaxy
(2018-10-09)
Cosmological simulations predict that an intergalactic magnetic field (IGMF) pervades the large scale structure (LSS) of the Universe. Measuring the IGMF is important to determine its origin (i.e. primordial or otherwise). ...
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 ...
