A Search for Radio-Quiet Gamma-Ray Pulsars in the EGRET Archive

چکیده
A progress report on our search for radio-quiet gamma-ray pulsars in the EGRET database is presented. The search technique utilizes signi cant computational resources of the Center for advanced Computing Research at Caltech to compute Gigapoint power spectra for some of the brighter, unidenti ed EGRET gamma-ray sources which, like Geminga, may not be visible at radio wavelengths. Two sources, GRO J2019+40 and GRO J1744-28, have been searched for pulsations to frequencies of 30 Hz and frequency derivatives to 10 11 Hz/s.

A Search for Radio-quiet Gamma-ray Pulsars
Most Galactic point sources of gamma rays remain unidentiÐed. The few (extrasolar) sources that have been identiÐed are all young, rotation-powered pulsars, all but one of which were identiÐed using radio ephemerides. The radio-quiet Geminga pulsar was identiÐed only after pulsations were discovered in a coincident X-ray source. Observational evidence indicates that many of the unidentiÐed Gala...
متن کاملOff-beam Gamma-ray Pulsars and Unidentified Egret Sources in the Gould Belt
We investigate whether gamma-ray pulsars viewed at a large angle to the neutron star magnetic pole could contribute to the new population of galactic unidentified EGRET sources associated with the Gould Belt. The faint, soft nature of these sources is distinctly different from both the properties of unidentified EGRET sources along the galactic plane and of the known gamma-ray pulsars. We explo...
متن کاملGamma-Ray Pulsars: Modeling and Searches
Using a likelihood analysis and EGRET detections, upper limits and diffuse background measurements, we find a best-fit luminosity law L ∝ PB for the gamma-ray pulsar population. We find that roughly 30 of the 170 unidentified EGRET sources are likely to be pulsars. This is roughly twice the number of known radio pulsars which are plausibly associated with unidentified EGRET sources. We predict ...
متن کاملGamma-ray Emission Properties from Mature Pulsars in the Galaxy and in the Gould Belt
We study the γ-ray emission properties of pulsars by using a new selfconsistent outer gap model. The outer gap can exist in pulsars with age over million years old if the effect of magnetic inclination angle as well as the average properties of the outer gap are considered. The mature γ-ray pulsars, whose ages are between 0.3 to 3 million years old, are able to move up to high galactic latitude...

The EGRET catalogue of unidentified X-ray sources has more objects along the galactic disk than at high galactic latitude, where identifications are comparatively easier. On the other hand, the Egret/GRO mission has already identified several known radio pulsars as gamma-ray sources as well as discovering Geminga's nature as a pulsar. If Geminga is not a unique case, as it is very likely not to...
