Spirals can do it, too – a spiral host in a 2 Mpc double-double lobed radio galaxy

Extragalactic jets, which are among the most powerful astrophysical phenomena, are collimated streams of gas ejected at high speeds from astronomical objects, in particular active galactic nuclei (AGNs). They can create huge clouds of matter bright at radio wavelengths, extending far beyond the boundaries of their host galaxy. If such sources reach sizes larger than 0.7 megaparsecs, we call them Giant Radio Galaxies (GRGs). Here we present an unusual object of this kind – a radio source J1350-1634 with two visible pairs of lobes, hosted by LEDA 896325 – the largest GRG hosted by a spiral galaxy known to date.
