CONTINUED TIMING OF PULSARS FOUND IN JERK SEARCHES OF FERMI UNASSOCIATED SOURCES

Abstract

The discovery of millisecond pulsars (MSPs) in radio searches of Fermi-LAT
unidentified sources continues. In order to fulfill the promise of these
discoveries, we must obtain phase-coherent rotational ephemerides over at least
one year. These are then used to fold sparse photons and obtain gamma-ray
pulsations, the starting point for subsequent studies. We plan to use the
GBT telescope to obtain timing solutions for 10 MSPs we have discovered
in unassociated LAT sources. Our work will determine if the new MSPs are
associated with the Fermi sources, contribute to future Fermi Pulsar Catalogs,
magnetospheric geometry studies and multi-wavelength pulsar emission models, and
evaluating the MSPs for inclusion in pulsar timing arrays for the detection of
gravitational waves.
