A rare example of low surface-brightness radio lobes in a gas-rich early-type galaxy: the story of NGC 3998

We study the nearby lenticular galaxy NGC 3998. This galaxy is known to host a low-power radio AGN with a kpc-size one-sided jet and a large, nearly polar HI disc. It is therefore a good system to study to understand the relation between the availability of cold-gas and the triggering of AGNs in gal...
