Abstract. The EGRET telescope aboard NASAs Comp-ton GRO has repeatedly detected 3EG J+, a bright and steady source of high-energy gamma-ray emis-sion with no identiﬁcation suggested until recently.

Some point sources in this map are pulsars along the plane. Seven pulsars are now known to emit in the gamma-ray portion of the spectrum, and five of these gamma-ray pulsars have been discovered since Compton was launched. The Crab and Geminga pulsars are found near the Galactic anticenter, on the extreme right side of the EGRET all-sky map. The Energetic Gamma-Ray Experiment Telescope (EGRET) instru ment on the Compton Gamma-Ray Observatory left as a legacy its Third Catalog of High Energy Gamma-Ray Sources, whose detections include a large number of blazars, some pulsars, the Large Magellanic Cloud and a .
GRO JOHN MATTOX TIMING THE GEMINGA PULSAR WITH HIGH-ENERGY GAMMA RAYS We propose to continue our study of the Geminga pulsar with a cycle 6 exposure. The unique contribution of Geminga to the study of pulsar emission mechanisms and spin-down demands ongoing observations by EGRET to refine its pulse ephemeris and improve the statistics of.

A reported e(+/-) annihilation line from the Crab pulsar is described on in this annual report, along with a astronomical model that was investigated theoretically and that displays all of the following properties discovered about this line:very strong (approximately Author: Malvin Ruderman.
The Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory has observed PSR B a number of times between and From these data, a more detailed picture of the gamma radiation from this source has been developed, showing several characteristics that distinguish this pulsar from others: the light curve is complex, with evidence of Author: Malvin Ruderman.
EGRET high-energy gamma-ray pulsar studies A survey GRO J is an X-ray pulsar; the Rapid Burster is not. The study of the six EGRET pulsars with Fermi is therefore very important. In this review we describe the current status of pulsar results from the high energy telescope EGRET (30 MeV - studies of high energy pulsars with EGRET book GeV) on the Compton Gamma Ray Observatory (CGRO) which has been in orbit and operation since April Before EGRET only two pulsars, the Crab (PSR B+21) and Vela (PSR B) pulsars, were known at gamma ray energies.
Pulsar Studies with GRO-COMPTEL (12) The 1 - 10 MeV Crab light curve integrated over the 4 observations is shown in fig. 2 (left); as expected from measurements in similar energy ranges (see for example Agrinier et al., ), the shape of the pulsed emission is characterized by two main peaks at about phase distance with an important.
The Gamma Ray Observatory (GRO) is currently planned for a launch from the space shuttle in After the long hiatus in high-energy gamma-ray astronomy since the end of the COS-B mission inthe Soviet missions Granat and Gamma-1 and the NASA mission GRO will resume observations in the energy range from below keV and extending to above 10 GeV.
Delivery of the final phase 4 data to the GRO SSC is on schedule, and delivery of the phase 5 preliminary data to the GRO SSC is also on schedule. Interaction with guest investigators continues at a good level. A paper entitled "EGRET High-Energy Gamma-Ray Pulsar Studies.
As part of its ongoing survey of the high-energy gamma-ray sky, the Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory has searched for emission from spin-powered.
The six EGRET gamma ray pulsars are among themost interesting objects in the sky observed by Fermi: they are bright galactic gamma ray sources and they have good and updated timing solutions. EGRET has studied these pulsars up to an energy of 10 GeV, and at least for the brightest three it has analyzed the evolution of the emission with phase.
The high-energy gamma-ray source 3EG J+ (also known as GRO J+59, 2EG J+, and GEV J+) has been subject of considerable interest since its discovery early in the CGRO mission by EGRET (Nolan et al.
Unidentified sources at high-energy gamma-ray wavelengths present significant challenges today. Summary The EGRET high energy gamma ray telescope on the Compton Gamma Ray Observatory is successfully carrying out significant observations on a wide variety of astronomical phenomena, including solar flares, gamma ray bursts, pulsars, galactic structure and active galactic nuclei.
The aim of the inaugural meeting of the Sant Cugat Forum on Astrophysics was to address, in a global context, the current understanding of and challenges in high-energy emissions from isolated and non-isolated neutron stars, and to confront the theoretical picture with observations of both the Fermi satellite and the currently operating ground-based Cherenkov telescopes.
of the high-energy gamma rays, viewing intervals are typi-cally weeks. PSR B was within 30 ° of the telescope axis during 23 of the CGRO viewing intervals to date.
No addi-tional EGRET observations of this pulsar are scheduled. Table 3 is a list of the EGRET observations, showing the dates, the angle between the pulsar and the EGRET. Abstract. The 3rd EGRET Catalog contains unidentified high-energy (E> MeV) gamma-ray sources, and there is great interest in the nature of these sources.
One means of determining sources class is the study of flux variability on time scales of days; pulsars are believed to be stable on these scales while blazars are known to be highly.
