X-ray and Gamma-ray Emission from Pulsar Magnetospheres
For polar-cap models based on electromagnetic cascades induced by curvature radiation of beam particles we calculate broad-band high-energy spectra of pulsed emission expected for classical (∼ 10 G) and millisecond pulsars (∼ 10 G). The spectra are a superposition of curvature and synchrotron radiation components and most of their detailed features depend significantly on the magnetic field str...
متن کاملX - ray , Radio , and Optical Observations of the Putative Pulsar in the Supernova Remnant CTA 1
A Chandra image of the central X-ray source RX J0007.0+7303 in the supernova remnant CTA 1 reveals a point source, a compact nebula, and a bent jet, all of which are characteristic of energetic, rotation-powered pulsars. Using the MDM 2.4m telescope we obtain upper limits in the optical at the position of the point source, (J2000) 00 h 07 m 01. these correspond to an X-ray-to-optical flux ratio...
متن کاملGamma-Ray Pulsar Visibility
PSR J0437-4715 is a millisecond pulsar (MSP) thought to be “pair formation starved” (having limited pair cascades due to magnetic photon absorption). Fortunately the general relativistic (GR) electrodynamical model under consideration applicable to this pulsar have few free parameters. We model PSR J0437-4715’s visibility [1], using a 3D model which incorporates the variation of the GR E-field ...
متن کاملThe Gamma Ray Pulsar Population
We apply a likelihood analysis to pulsar detections, pulsar upper limits, and diffuse background measurements from the OSSE and EGRET instruments on the Compton Gamma Ray Observatory to constrain the luminosity law for gamma-ray pulsars and some properties of the gamma-ray pulsar population. We find that the dependence of luminosity on spin period and dipole magnetic field is much steeper at OS...
