[37.07] HI absorption in radio loud ellipticals.

M. C. Blanton, J. H. van Gorkom (Columbia University Department of Astronomy), S. Baum (Space Telescope Science Institute)

We present the results of a VLA search for HI absorption in a sample of 24 radio loud ellipticals with compact cores. The sample consists of sources with a core flux larger than 100 mJy and lie within a redshift range of z= 0.01 to 0.1. With an angular resolution of 1 arcsec and a velocity resolution of 42 km/s we reach typical 5 sigma limits in optical depths of 0.01. We detect at least five of the 24 sources in HI absorption. In some of these the HI absorption is spatially resolved and we will present the kinematic structure. We will combine our results with those of previous searches and discuss the detection statistics and kinematics of the gas.
