Investigating Broadband Emission of the BL Lacertae Object 1ES 1959+650 between 2012 and 2024
ORAL
Abstract
Active galactic nuclei (AGN) host some of the most energetic processes in the universe, emitting relativistic jets of charged particles which emerge perpendicular to the galaxy's plane of rotation. BL Lacertae objects (BL Lac), a subclass of AGN, exhibit rapid variability and are expected to follow Synchrotron-Inverse-Compton (SIC) models. Motivated by past reports of deviation from SIC behavior, we conduct a broadband investigation of the BL Lac object 1ES 1959+650 to better understand its emission mechanisms. We analyze data from 2012-2024 from the Swift X-ray Telescope (XRT), the Fermi Large Area Telescope (LAT), the Whipple 48''optical telescope, and the Very Energetic Radiation Imaging Telescope Array System (VERITAS), binning daily to account for potential day-scale variability. Periods of elevated activity are selected and investigated in the context of an SIC emission model.
