Powerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-line Seyfert 1 (NLSy1) galaxies, thought to be young active galactic nuclei with low-mass black holes, harboring relativistic jets. Among them, sources hosting >100 kpc radio jets had been extremely rare but Umayal et al. report the discovery of large-scale, double-lobed radio structures in 33 NLSy1s. The images above are total intensity maps of two NLSy1 sources with projected sizes of at least 100 kpc, J1447+0806 (z=0.79) and J1617+1435 (z=0.66). The background grey images are the Pan-STARRS r-band images, while the contours are the radio images from RACS-low (887 MHz; violet), FIRST (1.4 GHz; green), and VLASS (3 GHz; red). The lower left corner of each image shows the beams of the different surveys. The team conclude that future observations of NLSy1 sources with the next-generation of sensitive telescopes may reveal a much larger population harboring large-scale jets, thus providing crucial clues on their origin, propagation, and interaction with the ambient environment.
