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 ...
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 ...
