VERITAS Observations of the Crab Pulsar
Benjamin Zitzer
The Crab pulsar has been widely studied across the electromagnetic spectrum from radio to gamma-ray energies. The exact nature of the emission processes taking place in the pulsar…
First combined studies on Lorentz Invariance Violation from observations of astrophysical sources
Leyre Nogués, Tony T. Y Lin, Cédric Perennes +9
Imaging Atmospheric Cherenkov Telescopes study the highest energy (up to tens of TeV) photon emission coming from nearby and distant astrophysical sources, thus providing valuable…
Background Systematic Studies in VERITAS Data
Benjamin Zitzer, VERITAS Collaboration
In the analysis of VERITAS and other IACT data, it is expected to get a distribution of statistical significances in sky map bins with mean of zero and width of unity in the absenc…
Lorentz Invariance Violation Limits from the Crab Pulsar using VERITAS
Benjamin Zitzer
Quantum gravity (QG) theories over the past fifty years have sought to understand the relationship between the four fundamental interactions. A major insight gained in this area is…
Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
Celine Armand, Eric Charles, Mattia di Mauro +13
Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…
Dark Matter Annihilation Limits from Dwarf Galaxies using VERITAS
Benjamin Zitzer
Current cosmological models and data suggest the existence of a cold Dark Matter (DM) component, however the nature of DM particles remains unknown. A favored candidate for DM is a…
The VERITAS Upgraded Telescope-Level Trigger Systems: Technical Details and Performance Characterization
Benjamin Zitzer
VERITAS is an array of imaging atmospheric Cherenkov telescopes sensitive to gamma rays in the energy range between 85 GeV and 30 TeV. The instrument underwent an upgrade of the ca…
Combined Dark Matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, HESS, MAGIC and VERITAS
Louise Oakes, Celine Armand, Eric Charles +13
The search for Dark Matter (DM) has great potential to reveal physics beyond the Standard Model. As such, searches for evidence of DM particles are being carried out using a wide r…
Search for Dark Matter from Dwarf Galaxies using VERITAS
Benjamin Zitzer
In the cosmological paradigm, cold dark matter (DM) dominates the mass content of the Universe and is present at every scale. Candidates for DM include many extensions of the stand…
