ARG0000fa1 - A triple?

  • Dolorous_Edd by Dolorous_Edd

    Separation is quite big, so this could be a triple or random arrangement

    VLA FIRST - centered at 12 34 58.47 +53 18 44.8 34 58.47 %2B53 18 44.8&Dec=&Equinox=J2000&ImageSize=10&MaxInt=10

    NVSS ( on the left ) , and WENSS: Westerbork Northern Sky Survey ( on the right ) 0.3 degree field or ~ 18 arcmin

    Anyway, coordinates of the suspected center ~12 34 58.47 +53 18 44.8

    yes, we had seen this one in 2012; SDSS J123458.46+531851.3, z_ph~0.62, size 11.4' or 4.3 Mpc, 3rd-largest source I know of!
