The interacting late-type host galaxy of the radio-loud narrow-line Seyfert 1 IRAS 20181-2244

Narrow-line Seyfert 1 galaxies (NLS1s) are a class of active galactic nuclei (AGN) which are known to be one of the few sources of \gamma rays, which originate in a relativistic beamed jet. Becuase of their relatively large distance, a poorly investigated aspect of these jetted NLS1s is their environment,... Show more
