Search for Ultraheavy Dark Matter from Observations of Dwarf Spheroidal Galaxies with VERITAS

A. Acharyya, A. Archer, P. Bangale, J. T. Bartkoske et autres

Dark matter is a key piece of the current cosmological scenario, with weakly interacting massive particles (WIMPs) a leading dark matter candidate. WIMPs have not been detected in their conventional parameter space (100 GeV $\lesssim M_χ \lesssim$ 100 TeV), a mass range …

VERITAS and Fermi-LAT constraints on the Gamma-ray Emission from Superluminous Supernovae SN2015bn and SN2017egm

A. Acharyya, C. B. Adams, P. Bangale, W. Benbow et autres

Superluminous supernovae (SLSNe) are a rare class of stellar explosions with luminosities ~10-100 times greater than ordinary core-collapse supernovae. One popular model to explain the enhanced optical output of hydrogen-poor (Type I) SLSNe invokes energy injection from a rapidly spinning magnetar. A …

VERITAS contributions to the 36th International Cosmic Ray Conference

A. U. Abeysekara, A. Archer, W. Benbow, R. Bird et autres

Compilation of papers presented by the VERITAS Collaboration at the 36th International Cosmic Ray Conference (ICRC), held July 24 through August 1, 2019 in Madison, Wisconsin.

Measurement of the iron spectrum in cosmic rays by VERITAS

Avery Archer, W. Benbow, R. Bird, Robert Brose et autres

We present a new measurement of the energy spectrum of iron nuclei in cosmic rays from 20 TeV to 500 TeV. The measurement makes use of a template-based analysis method, which, for the first time, is applied to the energy reconstruction of …

Detection of Pulsed Gamma Rays Above 100 GeV from the Crab Pulsar

E. Aliu, T. Arlen, T. Aune, M. Beilicke et autres

We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 giga-electron volts (GeV) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) array of atmospheric Cherenkov telescopes. The detection cannot be explained on the basis …

INSIGHTS INTO THE HIGH-ENERGY γ-RAY EMISSION OF MARKARIAN 501 FROM EXTENSIVE MULTIFREQUENCY OBSERVATIONS IN THE FERMI ERA

A. A. Abdo, M. Ackermann, Marco Ajello, A. Allafort et autres

We report on the γ-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) γ-ray spectrum of Mrk 501 can be well described by a single power-law function …

MULTIWAVELENGTH OBSERVATIONS OF LS I +61° 303 WITH VERITAS,SWIFT, ANDRXTE

V. A. Acciari, E. Aliu, T. Arlen, M. A. Bautista et autres

We present results from a long-term monitoring campaign on the TeV binary LSI +61° 303 with VERITAS at energies above 500 GeV, and in the 2–10 keV hard X-ray bands with RXTE and Swift , sampling nine 26.5 day orbital cycles between …

A Search for Dark Matter Annihilation with the Whipple 10 m Telescope

Marion Wood, G. Blaylock, S. M. Bradbury, J. H. Buckley et autres

We present observations of the dwarf galaxies Draco and Ursa Minor, the Local Group galaxies M32 and M33, and the globular cluster M15 conducted with the Whipple 10 m gamma-ray telescope to search for the gamma-ray signature of self-annihilating weakly interacting massive …
