Swift follow-up confirms the high flaring state of the blazar PMN J2345-1555
Abstract
Following the detection on 24 October 2010 of simultaneous optical and gamma-ray flares from the intermediate redshift (z=0.621) flat spectrum radio quasar PMN J2345-1555 by ATOM and Fermi LAT (ATel #2972), Swift target of opportunity observations have been performed on 27/28 October. Swift/XRT data were taken in Photon Counting mode for a total exposure of 9.7 ks. The X-ray spectrum (0.3-10 keV) can be fit by an absorbed power law model with a HI column density consistent with the Galactic value in the direction of the source.
