N2 - The ability to significantly increase the survey speed makes Phased Array Feeds (PAFs) the next revolution in radio astronomy instrumentation. This paper will present the latest commissioning and science results from the Focal L-Band Array for the Green Bank telescope (FLAG), which holds the current world record for PAF sensitivity. Since we are able to operate at system temperatures comparable with the traditional GBT single pixel L-Band feed, the increase in the field-of-view provided by the beamforming capabilities of PAFs results in a dramatic (∼ a factor of 5-7) increase in survey speeds. In particular, FLAG can probe similar neutral hydrogen column density regimes over a 4 sq. deg region in ∼ 30 minutes as opposed to four hours in an equivalent single pixel map. The multi-beam nature of PAFs also benefit radio transient science such as pulsar timing, blind pulsar surveys, and the search for elusive Fast Radio Bursts.
