High-temporal resolution optical observations of the gamma-ray blazer PG1553+113

We present here the results of an observational photo-polarimetry campaign at optical wavelengths of the blazar PG1553+113, which was recently detected at very high energies (> 100GeV) by the H.E.S.S and MAGIC γ-ray experiments. Our high-temporal resolution data show significant variations in the...

Sumario:We present here the results of an observational photo-polarimetry campaign at optical wavelengths of the blazar PG1553+113, which was recently detected at very high energies (> 100GeV) by the H.E.S.S and MAGIC γ-ray experiments. Our high-temporal resolution data show significant variations in the linear polarization percentage and position angle at inter-night time-scales, while at shorter (intra-night) time-scales both parameters varied less significantly, if at all. Simultaneous differential photometry (at the B and R bands) shows no significant variability in the total optical flux.
