Analysis of the blazar Markarian 421 with VERITAS

Markarian 421 (Mrk 421) is a well observed and highly variable blazar: an active galactic nucleus (AGN) with its relativistic jet pointed at Earth. Observations of Mrk 421 at VERITAS (the Very Energetic Radiation Imaging Telescope Array System) began in 2007, and it has been observed almost nightly in the winter since 2018, weather permitting. We analyzed the most up to date dataset with the most recent instrument response functions, some of which we created specifically for this analysis, to create a light curve showing the measured flux each day as a function of time. We will present the Mrk 421 light curve and other results from this work.
