A 350-MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources

ORAL

Abstract

We have searched for radio pulsations in 49 \fermi\ Large Area Telescope $\gamma$-ray source error ellipses using the Green Bank Telescope at a radio frequency of 350 MHz. We detected 14 millisecond pulsars (MSPs) in blind searches of the data. Four of these had already been discovered in other surveys. An additional four MSPs discovered in a subsequent radio survey at 820 MHz were detected by folding our survey data at the known periods and dispersion measures. This survey, along with other similar surveys, suggests that the majority of Galactic $\gamma$-ray sources at high Galactic latitudes are either MSPs or relatively nearby non-recycled pulsars. It also confirms that in the past there had been a strong observational bias against finding short orbital period MSP systems and a bias in favor of finding isolated MSPs.
