Description

Gamma-ray bursts (GRBs) are one of the most captivating extragalactic astrophysical phenomena. These transient events have been widely proposed as bright sources of the most energetic cosmic rays and gravitational waves. With its wide field of view (~2 str) and >95% duty cycle, the High Altitude Water Cherenkov (HAWC) Observatory, installed at 4100 m a.s.l. in the state of Puebla (Mexico), is the optimal instrument to search for VHE photons (> 100 GeV) from GRBs. We report results obtained from the analysis of a sample of GRBs detected by satellite instruments in the field of view of HAWC. We particularly discuss the case of GRB 170817A/GW 170817 that is associated to the first common detection of gravitational waves and multi-messenger observations of a merger of two neutron stars. We describe different search approaches currently used by HAWC, an all-sky search method as well as a real-time analysis of GRBs triggered by satellites. Results and physical implications are discussed in the framework of current GRB models.
