Multifrequency studies of the enigmatic gamma-ray source 3EG J1835+5918
Abstract
The EGRET telescope has repeatedly observed 3EG J1835+5918 as a bright and steady source of high-energy gamma-ray radiation which has not yet been indentified. EGRET data from CGRO observation cycle 1 to 7 have been reanalysed above 100 MeV and above 1 GeV. The gamma-ray source location represents the latest and probably final positional assessment based on EGRET data. We especially adress the question of flux variability and spectral variability. The results of a X-ray/optical identification campaign towards 3EG J1835+5918 are given. The one object which might be associated with the gamma-ray source 3EG J1835+5918 has the characteristics of an isolated neutron star and possible of a radio-quiet pulsar.
