Abstract

We present initial results from an ongoing search for pulsars and transients at 5 and 9 GHz with the Green Bank telescope. Survey targets include Sgr A* and its immediate vicinity, and a few specific sources in the region from the 2LC VLA survey by Cordes & Lazio (in preparation). Our search for dispersed single pulses discovered a Rotating Radio Transient (RRAT) candidate with a dispersion measure of 750 pc/cm^3 less than 4 arcminutes from Sgr A*. While the candidade's dispersion measure is too low to be associated with Sgr A*, investigating the presence and type of intermittent objects in the inner Galaxy has implications about modelling the neutron star population in the region and estimating the yield of future surveys.
