Optical Observations of NVSS 2146+82 and its Environs

Optical photometric and spectroscopic observations were obtained to identify the host galaxy of the radio emission and to measure its redshift. We began the search for the optical counterpart to the radio source using the Digitized Sky Survey ([Lasker et al. 1990]; hereafter DSS). The radio core is aligned with an elliptical galaxy on the DSS image to within the astrometric accuracy of the radio and optical positions from the NVSS and DSS. There is also a second, equally bright object a few arcseconds east of the galaxy at the radio core position. Finally, in the DSS image, there appears to be S-shaped diffuse emission that passes through both bright "nuclei''. Therefore, our initial assumption was that the host galaxy of NVSS 2146+82 was possibly a disturbed, double nucleus galaxy. In the following sections, we summarize the optical imaging of the field surrounding the candidate host galaxy and the spectroscopic observations of this host galaxy and its candidate galactic companions.
