Radio galaxy IC 4296 (PKS 1333-33). II. Spectroscopy, surface photometry, X-ray imaging, and infrared photometry
Spectroscopic and photometric observations of the radio jet galaxy IC 4296 are presented. The major axis rotation velocities are initially consistent with solid body rotation of angular velocity about 3 km/s/arcsec. Beyond a radius of roughly 20 deg, the rotation is approximately constant at 60 + or - 30 km/s. The velocity dispersion along the major axis shows a maximum of 340 + or - 30 km/s in the nucleus which then decreases with radius. A mass-to-light ratio of (13.2 + or - 3)h in solar units and a mass of (7.3 + or - 3) x 10 to the 11th solar masses are obtained. Color maps show U-B and B-V gradients interior to radius of roughly 10 arcsec. A partialy resolved X-ray source is coincident with IC 4296. 46 references.
