Left-archived HST/WFPC2 F656N image of 3C 249.1 (the redshifted [O III] 5007 falls into this filter), overlaid with contours of a VLA image at 5 GHz and 0.′′35 resolution (Gilbert et al. 2004). Contours at 0.5 x (1, 2, 4, 8) mJy/beam.

Description
English: Left-archived HST/WFPC2 F656N image of 3C 249.1 (the redshifted [O III] 5007 falls into this filter), overlaid with contours of a VLA image at 5 GHz and 0.′′35 resolution (Gilbert et al. 2004). Contours at 0.5 x (1, 2, 4, 8) mJy/beam. The peak of the radio continuum has been registered to the position of the quasar. The two x-ray emission regions (xa & xb) are marked in red and labeled. The gray-scale images in this and the middle panel have been allowed to wrap around to show both low-surface-brightness detail and high-surface-brightness peaks.Middle and Right -GMOS/IFU [O III] 5007 radial velocity broad-band channel maps with contours of the HST image and contours of the radio jet overlaid, respectively. The radial velocity range (relative to that of the nuclear narrow line region, z = 0.3117; negative velocities are blue shifted) is shown in each panel. The rectangles delineate the 3.′′5 x 5′′ FOV of GMOS/IFU. The crosses indicate the position of the quasar, which has been removed from the datacube.
