Redshifts and neutral hydrogen observations of compact symmetric objects in the COINS sample.
PECK A.B., TAYLOR G.B., FASSNACHT C.D., READHEAD A.C.S. and VERMEULEN R.C.
Abstract (from CDS):
The CSOs observed in the northern sky (COINS) sample is comprised of 52 CSO candidates identified in three VLBI surveys. Of these, 27 have now been confirmed as CSOs. Optical redshifts are available in the literature for 28 of the CSO candidates, and H I absorption has been detected toward four. We present new optical spectroscopic redshifts for three of the candidates and summarize the current status of optical identifications. We further report on the discovery of H I in absorption toward the CSO J1816+3457 and summarize the results of neutral hydrogen absorption studies of the sources in this sample.
