    what does "WAT" mean?


  • JeanTate by JeanTate

    Welcome to Radio Galaxy Zoo, DiNapoli!

    wide-angle tail; it's where the pair of jets/lobes from the core (the 'host', the galaxy with the super-massive black hole in its nucleus) do not appear as backo-to-back features, but are rather bent into two streams ('tails') that make an oblique angle (sorta).

    If the tails are bent so the angle is less than ~90 degrees, the morphology (shape) is called a NAT (narrow-angled tail).

    Hope this helps! 😃
