We present deep 1.4 GHz Very Large Array ( VLA ) radio continuum observations of two \sim half square degree fields in the Coma cluster of galaxies .
The two fields , “ Coma 1 ” and “ Coma 3 , ” correspond to the cluster core and southwest infall region and were selected on account of abundant pre-existing multiwavelength data .
In their most sensitive regions the radio data reach 22 \mu Jy rms per 4 \farcs 4 beam , sufficient to detect ( at 5 \sigma ) Coma member galaxies with L _ { 1.4 ~ { } GHz } = 1.3 \times 10 ^ { 20 } W Hz ^ { -1 } .
The full catalog of radio detections is presented herein and consists of 1030 sources detected at \geq 5 \sigma , 628 of which are within the combined Coma 1 and Coma 3 area .
We also provide optical identifications of the radio sources using data from the Sloan Digital Sky Survey ( SDSS ) .
The depth of the radio observations allows us to detect AGN in cluster elliptical galaxies with M _ { r } < -20.5 ( AB magnitudes ) , including radio detections for all cluster ellipticals with M _ { r } < -21.8 .
At fainter optical magnitudes ( -20.5 < M _ { r } \lesssim - 19 ) the radio sources are associated with star-forming galaxies with star formation rates as low as 0.1 M _ { \odot } yr ^ { -1 } .
