Abstract
The identification of Geminga, the second brightest source in the sky above 100 MeV, as a radio quiet pulsar opened a new window of study for neutron stars . Here we summarize multiwavelength observations of two radio quiet pulsar candidates among unidentified EGRET sources: 2EG J2020+4026 (gamma-Cygni) and 2EG J0008+73 (CTA 1).
