This is an AAS-level poster that describes some of CGRO's most exciting scientific accomplishments. Three results are given for each of the four instruments in the form of an image plus an explanatory caption. These were contributed by members of the instrument teams. The poster was designed by Carol Ladd at the Graphics Department at Goddard Space Flight Center. Larger images of the poster and its contents can be viewed by clicking on the thumbnail images below. Questions or comments regarding the poster itself may be sent to Peter Leonard.

Poster Content

CGRO

The Compton Gamma Ray Observatory has studied the gamma-ray
sky from 15 keV to 30 GeV since its launch in 1991.

BATSE

BATSE GRBs

Demonstrated that gamma-ray burst sources are distributed in a manner consistent with a cosmological population.
BATSE Occultation

Monitoring of hard X-ray sources and searching for new transients via Earth occultation.
BATSE SGRs

Discovery of soft gamma repeater SGR 1627-41.


COMPTEL

COMPTEL 1-30 MeV

Produced first-ever 1 to 30 MeV all-sky map.
COMPTEL 26Al

Produced all-sky map of 26Al emission with unprecedented quality.
COMPTEL June 15

Observed neutrons from June 15, 1991 solar flare.


EGRET

EGRET_3rd_Cat

More than 60% of high-energy gamma-ray sources are unidentified.

EGRET_Blazar

Established gamma-ray quasars, or blazars, as a class of sources.

EGRET_Geminga

Demonstrated that gamma-ray emission can dominate in pulsars.



OSSE

OSSE_511_keV_maps

First determination of spatially extended 511 keV annihilation line radiation from Galactic center region.

OSSE_June_4

Observed gamma-ray emission lines from June 4, 1991 solar flare.

OSSE_Seyfert

Established that spectra of Seyfert galaxies have high-energy cutoffs above a few hundred keV.
