4 Jan 2015 | | Abstract: | We systematically analyze the 6-year Fermi/LAT data of the lobe-dominated
quasars (LDQs) in the complete LDQ sample from 3CRR survey and report the
discovery of high-energy gamma-ray emission from 3C 275.1. The gamma-ray
emission likely associating with 3C 207 is confirmed and significant
variability of the lightcurve is identified. We do not find statistically
significant gamma-ray emission from other LDQs. 3C 275.1 is the known
gamma-ray quasar with the lowest core dominance parameter (i.e., R=0.11). We
also show that both the northern radio hotspot and parsec jet models provide
acceptable descriptions to the gamma-ray data. Considering the potential
gamma-ray variability at the timescale of months, the latter is probably more
favorable. The number of gamma-ray LDQs would increase when the exposure
accumulates and hence LDQs could be non-ignorable contributors for the
extragalactic gamma-ray background. | | Source: | arXiv, 1501.0635 | | Services: | Forum | Review | PDF | Favorites | |
