Faint Radio Sources and the Cosmic Microwave Background
We have mapped a single field with the VLA to an unprecedented rms sensitivity of 1.5 µJy. Our observations reveal that the excess µJy population (see Windhorst et al (1993), Fomalont et al. (1993)) is continuous down to 1 µJy. In addition, we measure a microwave sky temperature of ΔT/T = (1.4 ± 1.2) x 10−5, consistent with microwave decrements we discovered near the center of our map.
