Multiwavelength Study Of Two Unidentified Gamma-ray Sources
Abstract
Most counterparts of the identified low-latitude gamma-ray sources are Isolated Neutron Stars (INSs). They are characterized by an extremely high value of the X/optical flux ratio, therefore a systematic X-ray/optical coverage of the fields of unidentified low-latitude gamma-ray sources is the best way to unveil possible INS counterparts. Since the low-latitude sources are heavily affected by the interstellar absorption in both the X-ray and optical bands, we decided to apply the above strategy to two middle-latitude EGRET sources, which could belong to a local galactic population: 3EG J0616-3310 and 3EG J1249-8330. Here we report on the global X-ray characterisation of about 300 objects, on their candidate optical counterparts and on the preliminary results of their identification.
