ARG0003a3y - core and one-sided lobe; host a not-boring elliptical?

  • JeanTate by JeanTate

    At z_ph 0.092±0.0224/0.106±0.0267, SDSS J155203.47+073141.9 is fairly local; what sort of galaxy is it?

    We can apply various quantitative measures, but simple visual inspection suggests it's not an elliptical.

    Is it, however, the host? Of the nuclear emission, certainly; of the extended emission to the south?
