Abstract

We present a new sample of 84 large angular size radio galaxies selected from the NRAO VLA Sky Survey. Radio sources with declination above +60, total flux density greater than 100 mJy at 1.4 GHz and angular size larger than 4 0 have been selected and observed with the VLA at 1.4 and 4.9 GHz. The radio observations attempt to conrm the large angular size sources and to isolate the core emission for optical identication. In this paper, the rst of a series of three, we present radio maps of 79 sources from the sample and discuss the eects of the selection criteria in the nal sample. 37 radio galaxies belong to the class of giants, of which 22 are reported in this paper for the rst time.
