Pulsar Timing for the Fermi Gamma-ray Space Telescope

D. A. Smith, L. Guillemot, F. Camilo +25

We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of…

New pulsar rotation measures and the Galactic magnetic field

Aristeidis Noutsos, Simon Johnston, Michael Kramer +1

We measured a sample of 150 pulsar Rotation Measures (RMs) using the 20-cm receiver of the Parkes 64-m radio telescope. 46 of the pulsars in our sample have not had their RM values…

Discovery of two candidate pulsar wind nebulae in very-high-energy gamma rays

H. E. S. S. Collaboration, :, F. Aharonian

We present the discovery of two very-high-energy gamma-ray sources in an ongoing systematic search for emission above 100 GeV from pulsar wind nebulae in survey data from the H.E.S…
