TL;DR: The High Altitude Water Cherenkov (HAWC) observatory as mentioned in this paper is an array of large water-cherenkov detectors sensitive to gamma rays and hadronic cosmic rays in the energy band between 100 GeV and 100 TeV.

TL;DR: In this paper, the sensitivity of HAWC to Gamma Ray Bursts (GRBs) has been evaluated using two data acquisition (DAQ) systems: the main DAQ system reads out coincident signals in the tanks and reconstructs the direction and energy of individual atmospheric showers, and the scaler DAQ counts the hits in each photomultiplier tube (PMT) in the detector and searches for a statistical excess over the noise of all PMTs.

TL;DR: In this article, an analysis of the cosmic-ray arrival direction distribution based on 4.9 × 1010 events recorded between 2013 June and 2014 February shows anisotropy at the 10−4 level on angular scales of about 10°.

TL;DR: The High-Altitude Water Cherenkov (HAWC) Observatory is sensitive to gamma rays and charged cosmic rays at TeV energies as discussed by the authors, and an analysis of the cosmic-ray arrival direction distribution based on $4.9\times 10^{10}$ events recorded between June 2013 and February 2014 shows anisotropy at the $10-4}$ level on angular scales of about $10^\circ.

TL;DR: Abeysekara et al. as discussed by the authors studied the HAWC sensitivity to gamma-ray signatures of high-mass (multi-TeV) dark matter annihilation.
