Sažetak
The blazar PG 1553+113 is a well known TeV γ- ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi- frequency data in order to study its emission processes. An extensive campaign was carried out between March and April 2008, where optical, X-ray, high-energy (HE) γ-ray, and very-high-energy (VHE) γ-ray data were obtained with the KVA, Abastumani, REM, RossiXTE/ASM, AGILE and MAGIC telescopes, respectively. This is the first simultaneous broad-band (i.e., HE+VHE) γ-ray observation, though AGILE did not detect the source. We combine data to derive source’s spectral energy distribution and interpret its double peaked shape within the framework of a synchrotron self compton model.
