The faint radio population contains a higher proportion of star-forming galaxies (SFGs) and radio-quiet or non-jetted active galactic nuclei (AGN) below radio flux densities of approximately 100 microJy. It is commonly understood that radio emission in SFGs is primarily thermal and for radio-loud AGN, it is mainly non-thermal. The radiative mechanisms producing radio emission in non-jetted...
$\gamma$-ray emitting narrow-line Seyfert 1 galaxies ($\gamma$-NLS1) are jetted, $\gamma$- and radio-loud sources of a very puzzling sub-class of Active Galactic Nuclei (AGN), exhibiting properties similar to low power flat-spectrum radio quasars (FSRQs), but not quite identical. They are characterised by relatively low black hole masses and extremely high, near-Eddington accretion rates, with...
Hydra A is a FR-I type radio galaxy located at the centre of the Abell 780 cluster with a redshift of $ z = 0.054$. Previous observations of the radio galaxy have been conducted at low frequencies by the Very Large Array (VLA) telescope and using the L-band frequencies of the MeerKAT array telescope. The Chandra X-ray observatory also carried out a detailed survey of the X-ray emission from...
