However, the origin of 31% of the detected gamma-ray sources remains unknown. The lack of counterpart at longer wavelengths might suggest that there are no sufficiently sensitive low energy observations of these sources. Multi-wavelength observations of these sources are fundamental to identify and reveal their nature, as well as to understand the physics behind these energetic sources. The identification of any of these sources, by locating its counterpart at radio, infrared, optical or X-ray wavelength would improve our knowledge of the emission processes at high energies and would help to solve the problem of unidentified high energy sources. We have started a longterm campaign to detect some of the unidentified sources in the low-freuqency radio regime from the GMRT, and propose to provide a complete picture using the existing observations and detections of these sources in other wavelengths. Here we report the detection of one source, 2FGL J0307.4+4915, in three frequencies. We also discuss the likely properties of this source. |
