A SEARCH FOR PULSATIONS FROM GEMINGA ABOVE 100 GeV WITH VERITAS
Journal: The Astrophysical Journal
Year: 2015

We present the results of 71.6 hr of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS veryhigh-energy gamma-ray telescope array. Data taken with VERITAS between 2007 November and 2013 February were phase-folded using a Geminga pulsar timing solution derived from data recorded by the XMM-Newton and Fermi-LAT space telescopes. No significant pulsed emission above 100 GeV is observed, and we report upper limits at the 95% confidence level on the integral flux above 135 GeV (spec
