Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth
A. U. Abeysekara, A. Albert, R. Alfaro +113
The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…
A Search for Dark Matter in the Galactic Halo with HAWC
A. U. Abeysekara, A. M. Albert, R. Alfaro +100
The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is a wide field-of-view observatory sensitive to 500 GeV - 100 TeV gamma rays and cosmic rays. With its observations…
The X-ray counterpart to the gravitational wave event GW 170817
E. Troja, L. Piro, H. van Eerten +31
A long-standing paradigm in astrophysics is that collisions- or mergers- of two neutron stars (NSs) form highly relativistic and collimated outflows (jets) powering gamma-ray burst…
Modeling the high-energy emission in GRB 110721A and implications on the early multiwavelength and polarimetric observations
N. Fraija, W. H. Lee, M. Araya +3
GRB 110721A was detected by the Gamma-ray Burst Monitor and the Large Area Telescope (LAT) onboard the Fermi satellite and the Gamma-ray Burst Polarimeter onboard the IKAROS solar…
The HAWC real-time flare monitor for rapid detection of transient events
A. U. Abeysekara, R. Alfaro, C. Alvarez +105
We present the development of a real-time flare monitor for the High Altitude Water Cherenkov (HAWC) observatory. The flare monitor has been fully operational since 2017 January an…
Search for very-high-energy emission from Gamma-ray Bursts using the first 18 months of data from the HAWC Gamma-ray Observatory
The HAWC collaboration, R. Alfaro, C. Alvarez +102
The High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory is an extensive air shower detector operating in central Mexico, which has recently completed its first two years of…
Daily monitoring of TeV gamma-ray emission from Mrk 421, Mrk 501, and the Crab Nebula with HAWC
A. U. Abeysekara, A. Albert, R. Alfaro +104
We present results from daily monitoring of gamma rays in the energy range to TeV with the first 17 months of data from the High Altitude Water Cherenkov (HAWC)…
Search for Very High Energy Gamma Rays from the Northern Bubble Region with HAWC
A. U. Abeysekara, A. Albert, R. Alfaro +108
We present a search of very high energy gamma-ray emission from the Northern Bubble region using data collected with the High Altitude Water Cherenkov (HAWC) gamma…
Photometric Observations of Supernova 2013cq Associated with GRB 130427A
R. L. Becerra, A. M. Watson, W. H. Lee +18
We observed the afterglow of GRB 130427A with the RATIR instrument on the 1.5-m Harold L. Johnson telescope of the Observatorio Astronómico Nacional on Sierra San Pedro Mártir. Our…
The 2HWC HAWC Observatory Gamma Ray Catalog
A. U. Abeysekara, A. Albert, R. Alfaro +108
We present the first catalog of TeV gamma-ray sources realized with the recently completed High Altitude Water Cherenkov Observatory (HAWC). It is the most sensitive wide field-of-…
Multiwavelength follow-up of a rare IceCube neutrino multiplet
M. G. Aartsen, M. Ackermann, J. Adams +501
On February 17 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another, consistent with comi…
Observation of the Crab Nebula with the HAWC Gamma-Ray Observatory
A. U. Abeysekara, A. Albert, R. Alfaro +104
The Crab Nebula is the brightest TeV gamma-ray source in the sky and has been used for the past 25 years as a reference source in TeV astronomy, for calibration and verification of…
