TL;DR

The HAWC Gamma-Ray Observatory is a high-altitude detector that measures gamma rays from 100 GeV to 100 TeV, capable of detecting steady, extended, diffuse, and transient gamma-ray sources with high sensitivity.

Contribution

This paper details the sensitivity of HAWC to various gamma-ray sources, including extended regions, diffuse emission, and transient events, and presents the first Crab Nebula measurement with HAWC-30.

Findings

01

Sensitive to gamma rays from 100 GeV to 100 TeV

02

Able to detect extended and diffuse gamma-ray emission

03

First measurement of the Crab Nebula with HAWC-30

Abstract

The High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is designed to record air showers produced by cosmic rays and gamma rays between 100 GeV and 100 TeV. Because of its large field of view and high livetime, HAWC is well-suited to measure gamma rays from extended sources, diffuse emission, and transient sources. We describe the sensitivity of HAWC to emission from the extended Cygnus region as well as other types of galactic diffuse emission; searches for flares from gamma-ray bursts and active galactic nuclei; and the first measurement of the Crab Nebula with HAWC-30.
