Simultaneous multi - frequency observations of PG 1553 + 113

چکیده
We report simultaneous multi-frequency observations of the blazar PG 1553+113, that were carried out in March-April 2008. Optical, X-ray, high-energy (HE: ≥ 100 MeV) γ-ray, and very-highenergy (VHE: ≥ 100 GeV) γ-ray data were obtained with the KVA, REM, RossiXTE/ASM, AGILE and MAGIC telescopes. This is the first simultaneous broad-band (i.e., HE+VHE) γ-ray observation of a blazar. The source spectral energy distribution derived combining these data shows the usual doublepeak shape, and is interpreted in the framework of a synchrotron-self-Compton model.

PG 1553+113 is a very-high-energy (VHE, E > 100 GeV) γ-ray emitter classified as a BL Lac object. Its redshift is constrained by intergalactic absorption lines in the range 0.4 < z < 0.58. The MAGIC telescopes have monitored the source’s activity since 2005. In early 2012, PG 1553+113 was found in a high-state, and later, in April of the same year, the source reached the highest VHE flux state ...
متن کاملPg 1553+113: Five Years of Observations with Magic
We present the results of five years (2005–2009) of MAGIC observations of the BL Lac object PG 1553+113 at very high energies (VHEs, E > 100GeV). Power law fits of the individual years are compatible with a steady mean photon index Γ = 4.27 ± 0.14. In the last three years of data, the
متن کاملA new upper limit on the redshift of PG 1553+113 from observations with the MAGIC Telescope
Very high energy gamma ray emission from the active galactic nucleus PG 1553+113 was observed during 2005 and 2006 by the MAGIC collaboration, for a total observation time of 18.8 hours. Here we present the results of follow up observations: more than 20 hours of good quality data collected by the MAGIC Telescope during the 2007 and 2008 campaigns. The obtained spectra are compared and combined...

متن کاملDetection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
The MAGIC telescope has observed very-high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8σ . The light curve shows no significant flux variations on a daily timescale. The flux level during 2005 was, however, significantly higher as compared to 2006. The differential energy spectrum between ∼90 GeV and 500 GeV is well described by...
