An unusual radio galaxy in Abell 428: A Large powerful FR I source In A disk-dominated Host

摘要

We report the discovery of a powerful (～ 10~24 h~-2_75 WHz~-1 at 20 cm) FR I radio source in a highly flattened disk-dominated galaxy. Half the radio flux from this source is concentrated within the host galaxy, with the remainder in a pair of nearly symmetrical lobes of total extent ～200 kpc nearly perpen- dicular to the disk. Traditional wisdom maintains that powerful, extended radio sources are found only in ellipticals or recent merger events. We report B, R. J. And K imaging, optical spectroscopy, a rotation curve, an IRAS detection, and a VLA 20 cm image for this galaxy, 0313-192.
