Abstract:
The imaging Compton telescope COMPTEL aboard NASA's Compton Gamma-Ray
Observatory (CGRO) has opened the MeV gamma-ray band as a new window
to astronomy. COMPTEL provided the first complete all-sky survey in
the energy range 0.75 to 30MeV. The catalogue, presented here, is
largely restricted to published results. It contains firm as well
as marginal detections of continuum and line emitting sources and
presents upper limits for various types of objects. The numbers of
the most significant detections are 32 for steady sources and 31 for
gamma-ray bursters. Among the continuum sources, detected so far, are
spin-down pulsars, stellar black-hole candidates, supernova remnants,
interstellar clouds, nuclei of active galaxies, gamma-ray bursters,
and the Sun during solar flares. Line detections have been made in the
light of the 1.809MeV 26Al line, the 1.157MeV 44Ti line, the 847
and 1238keV 56Co lines, and the neutron capture line at 2.223MeV.
For the identification of galactic sources, a modelling of the diffuse
galactic emission is essential. Such a modelling at this time does not
yet exist at the required degree of accuracy. Therefore, a second
COMPTEL source catalogue will be produced after a detailed and
accurate modelling of the diffuse interstellar emission has become
possible.
