چکیده
| The Compton Gamma-Ray Observatory has completed 4 years of observations comprising a full-sky survey and several deep pointings. The Crab is one of the strongest permanent sources in the CGRO energy range (20 keV to 10 GeV). Its total (pulsed and unpulsed) emission is often used as a calibration standard. We present the results of an analysis of data from all four CGRO instruments obtained during contemporaneous Crab observations made during Phase I, II and III between 1991 and 1994. Emphasis is given to the cross-calibration of the four CGRO instruments.

The COMPTEL experiment aboard the Compton Gamma-Ray Observatory (CGRO) has observed the gamma-ray blazar 3C 279 several times between April 1991 and September 1995. This paper reports on a consistent analysis of these observations using the most recent COMPTEL data analysis tools. Detections and non-detections of 3C 279 along the CGRO-mission indicate a time-variable MeVflux. Spectral variabili...
متن کاملChasing the second gamma - ray bright isolated neutron star : 3 EG J 1835 + 5918 / RX J 1836 . 2 + 5925
The EGRET telescope aboard NASAs Comp-ton GRO has repeatedly detected 3EG J1835+5918, a bright and steady source of high-energy gamma-ray emission with no identification suggested until recently. The long absence of any likely counterpart for a bright gamma-ray source located 25 • off the Galactic plane initiated several attempts of deep observations at other wavelengths. We report on counterpa...
متن کاملTcer Working Paper Series Golden Rule Optimality in Stochastic Olg Economies
This study examines conditional golden rule optimality (CGRO) in stochastic overlapping generations models to complement the existing results on conditional Pareto optimality (CPO). Although an example in which CPO implies CGRO is presented, it is shown that such a situation is avoidable under strictly convex preferences. Under such preferences, both CPO and CGRO are characterized by the condit...

We use all COMPTEL data from the beginning of the CGROmission (April ’91) up to the end of CGRO Cycle 6 (November ’97) to carry out all-sky point source analyses in the four standard COMPTEL energy bands for different time periods. We apply our standard maximum-likelihood method to generate all-sky significance and flux maps for point sources by subtracting off the diffuse emission components v...
متن کاملThe variable X/γ-ray spectrum of the Seyfert 2 galaxy NGC7172
A broad band X-, gamma-ray spectral study of the Seyfert 2 galaxy NGC 7172 is presented. We use our ASCA observations from May 1995 and combine these with the CGRO OSSE data from March 1995. The only Seyfert 2 galaxy previously to have been modelled over such a broad spectral range is NGC 4945. The ASCAGIS data alone, can be acceptably described by a model consisting of a power law,with a photo...
