abstract

VERITAS is an array of four 12-m atmospheric Cherenkov telescopes, designed to observe the very-high-energy (VHE; E $\geq$100 GeV) sky. Since 2007, it has detected more than 20 extra-galactic sources, the majority of which are active-galactic-nuclei of the blazar class. In this paper we present a selection of the most recent results from the VERITAS blazar observing program, in particular in the context of broad-band multi-wavelength campaigns. Four results are highlighted: the detection of the flat-spectrum-radio-quasar PKS 1222+216 (4C +21.35) during March 2014; the $\gamma$-ray flare from the BL Lac object 1ES 1727+502, observed under bright-moonlight conditions during May 2013; the bright $\gamma$-ray flare from the BL Lac object 1ES 1011+496 during February 2014; and the long-term campaign on the BL Lac object PKS 1424+240, currently the farthest (z > 0.60), persistent VHE emitter

  1. Statistical Insights into Flux and Photon Index Distributions of VHE FSRQs from Fermi-LAT Observations

    astro-ph.HE 2025-05 conditional novelty 4.0 of 10

    VHE FSRQs show double lognormal flux and photon index distributions at 3-day and 7-day binning, supporting the two-flux-state hypothesis.
