GPS Timing and Control System of the HAWC Detector
Anushka Udara Abeysekara, Tilan N. Ukwatta, Dan Edmunds +4
The design and performance of the GPS Timing and Control (GTC) System of the High Altitude Water Cerenkov (HAWC) gamma ray observatory is described. The GTC system provides a GPS s…
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…
Inclusive cross sections, charge ratio and double-helicity asymmetries for and production in collisions at =200 GeV
A. Adare, C. Aidala, N. N. Ajitanand +378
We present the midrapidity charged pion invariant cross sections and the ratio of -to- production ( GeV/), together with the double-helicity asymmetries ($5<…
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…
