Abstract

The VLA FIRST survey now encompasses 5000 sq. deg., mostly in the north Galactic Cap. The First survey generates images of the sky at 1400 MHz with a sensitivity to point sources down to 1 mJy with positions accurate to 1 arcsec (90% confidence). The survey finds approximately 85 discrete sources per sq. degree. Detailed information about the FIRST survey can be obtained at http://sundog.stsci.edu. At the level of the POSS 1, 15% of FIRST sources have optical counterparts. While these are primarily galaxies, there are significant numbers of quasars and stars detected in the survey. This presentation will highlight some of the research being pursued by the FIRST science team.
