Title: OPTICAL COUNTERPARTS FOR TOP LAT MSP CANDIDATES

Abstract: We propose a program of optical imaging and spectroscopy to study counterparts for the best and brightest LAT unidentified sources. These are likely extreme (short period/strong wind) binary millisecond pulsars and the data will constrain the orbital properties, enabling a meaningful search for pulsations directly in the LAT gamma-ray data. We augment this with narrow band images of Halpha bow shocks around these sources and known high power LAT pulsars. A combination of 4m SOAR discovery observations, 2m LCO follow-up queue photometry and 8m GMOS follow-up queue spectroscopy deliver accurate orbital parameters enabling LAT pulse discovery. The measurements also probe binary heating and spindown energetics to constrain the pulsar physics.
