HX-POL - A Balloon-Borne Hard X-Ray Polarimeter
H. Krawczynski, A. Garson, Q. Li +10
We report on the design and estimated performance of a balloon-borne hard X-ray polarimeter called HX-POL. The experiment uses a combination of Si and Cadmium Zinc Telluride detect…
Pair-Starved Pulsar Magnetospheres
Alex G. Muslimov, Alice K. Harding
We propose a simple analytic model for the innermost (within the light cylinder of canonical radius) structure of open-magnetic-field lines of a rotating neutron star (NS) with rel…
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…
The Geminga Fraction
Alice K. Harding, Isabelle A. Grenier, Peter L. Gonthier
Radio-quiet gamma-ray pulsars like Geminga may account for a number of the unidentified EGRET sources in the Galaxy. The number of Geminga-like pulsars is very sensitive to the geo…
Correlations between pulsed X-ray flux and radio arrival time in the Vela pulsar
A. N. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
Correlation between X-ray Lightcurve Shape and Radio Arrival Time in the Vela Pulsar
A. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
Particle Acceleration in Pair-Starved Pulsars
Alex G. Muslimov, Alice K. Harding
We investigate the physical situation above the pulsar polar cap (PC) where the accelerating primaries (electrons) are not capable of producing sufficient numbers of electron-posit…
Gamma-Ray Pulsars: Models and Predictions
Alice K. Harding
Pulsed emission from gamma-ray pulsars originates inside the magnetosphere, from radiation by charged particles accelerated near the magnetic poles or in the outer gaps. In polar c…
Gamma-ray and X-ray luminosities from spin-powered pulsars in the full polar cap cascade model
Bing Zhang, Alice K. Harding
We modify the conventional curvature radiation (inverse Compton scattering) + synchrotron radiation polar cap cascade model by including the inverse Compton scattering of the highe…
Gamma Ray Pulsars: Emission from Extended Polar Cap Cascades
Joseph K. Daugherty, Alice K. Harding
We have used a Monte Carlo simulation of a Polar Cap (PC) model of gamma-ray pulsars to estimate light curves and phase-resolved spectra for sources whose rotational and magnetic a…
Elimination of resonant divergences from QED in super-strong magnetic fields
Carlo Graziani, Alice K. Harding, Ramin Sina
We study the resonant divergences that occur in quantum scattering cross-sections in the presence of a strong external magnetic field. We demonstrate that all such divergences may…
