[GA224] VERITAS Long Term Monitoring of Gamma-Ray Emission from the BL Lacertae Object
BL Lacertae is the prototype of the blazar subclass known as “BL Lac type objects”. BL Lacertae itself is a low-frequency-peaked BL Lac (LBL). Very high energy (VHE, Energy > 200 GeV) gamma-ray emission from this source was discovered in 2005 by the MAGIC observatory while the source was in a flaring state. Since then, VHE gamma rays from this source have been detected over various epochs. In each of the detection epochs the source was at an active state. It is possible that the active states are composed of a convolution between a quiescent component and a temporary elevated component. Observing BL Lacertae at both quiescent and active states is the key to disentangling these two components. VERITAS is monitoring BL Lacertae since 2011. The archival dataset includes observations during active and quiescent states. This presentation reports on the preliminary results of the VERITAS observation between January 2011 - October 2016, as well as contemporaneous multiwavelength observations.
