Full description

We propose to observe the core region of the Sagittarius dwarf spheroidal (Sgr dSph) galaxy with the Parkes Ultra-Wideband Low (UWL) receiver and the goal is to search for new millisecond pulsars (MSPs). Recent studies of diffused gamma-ray emission in the Galactic Bulge strongly indicate that Sgr dSph might also be shining at high energies. The summed gamma-ray emission from a population of millisecond pulsars is the most promising alternative explanation. The discovery of MSPs in Sgr dSph will allow us to study pulsar formation and evolution in various environments, probe the evolutionary history of the galaxy and interstellar medium in the Milky Way's halo, and constrain the potential contributions from dark matter annihilation to the observed gamma-ray emission.
