First background-free limit from a directional dark matter experiment: results from a fully fiducialised DRIFT detector
J. B. R. Battat, J. Brack, E. Daw +28
The addition of O2 to gas mixtures in time projection chambers containing CS2 has recently been shown to produce multiple negative ions that travel at slightly different velocities…
Search for gamma-rays from the unusually bright GRB 130427A with the HAWC Gamma-ray Observatory
The HAWC collaboration, A. U. Abeysekara, R. Alfaro +90
The first limits on the prompt emission from the long gamma-ray burst (GRB) 130427A in the energy band are reported. GRB 130427A was the most powerful b…
VAMOS: a Pathfinder for the HAWC Gamma-Ray Observatory
A. U. Abeysekara, R. Alfaro, C. Alvarez +133
VAMOS was a prototype detector built in 2011 at an altitude of 4100m a.s.l. in the state of Puebla, Mexico. The aim of VAMOS was to finalize the design, construction techniques and…
Observation of Small-scale Anisotropy in the Arrival Direction Distribution of TeV Cosmic Rays with HAWC
A. U. Abeysekara, R. Alfaro, C. Alvarez +96
The High-Altitude Water Cherenkov (HAWC) Observatory is sensitive to gamma rays and charged cosmic rays at TeV energies. The detector is still under construction, but data acquisit…
Milagro Limits and HAWC Sensitivity for the Rate-Density of Evaporating Primordial Black Holes
A. A. Abdo, A. U. Abeysekara, R. Alfaro +118
Primordial Black Holes (PBHs) are gravitationally collapsed objects that may have been created by density fluctuations in the early universe and could have arbitrarily small masses…
The Sensitivity of HAWC to High-Mass Dark Matter Annihilations
A. U. Abeysekara, R. Alfaro, C. Alvarez +101
The High Altitude Water Cherenkov (HAWC) observatory is a wide field-of-view detector sensitive to gamma rays of 100 GeV to a few hundred TeV. Located in central Mexico at 19 degre…
