Blazar 1ES 1959+650 investigated with Swift and XMM-Newton satellites arxiv
High synchrotron energy peaked blazar 1ES 1959+650 is studied with Swift and XMM-Newton satellite in total 127 observations during the period June 2018-December 2020. We extensively studied its flux and spectral variability on intra-day and long-term timescales. Discrete correlation function analysis between soft and hard X-ray bands indicates soft as well as hard lags. The results are used to constrain the magnetic field of the emitting region which is found to be 0.64 Gauss.
The spectral energy distribution around the synchrotron peak is well described by the log parabola model. Spectral parameters like peak energy E$_{p}$, curvature $\beta$ and the peak luminosity L$_{p}$ are derived from spectral analysis. Their correlations are studied to constrain the acceleration processes of the emitting particles.
