Abstract
We search for gamma-ray emission from OJ287 in the energy range from 0.1-300 GeV during 2015-2023, in coincidence with an extensive observing campaign to monitor the optical flux variability and polarization, as discussed in arXiv:2311.02372. We present results for eight segments in the aforementioned period, with each segment corresponding to an observing season. We report non-zero gamma-ray flux (with >10σ significance) for all the eight segments. The photon and energy flux observed during this period is and , respectively, while the SED can be fitted with a power law with a slope of 2.12±0.02. The observed luminosity is between 1045−1046 ergs/sec.
