An optimized search for dark matter in the galactic halo with HAWC

A. Albert, R. Alfaro, C. Alvarez +63

The Galactic Halo is a key target for indirect dark matter detection. The High Altitude Water Cherenkov (HAWC) observatory is a high-energy (~300 GeV to >100 TeV) gamma-ray detecto…

Characterization of the background for a neutrino search with the HAWC observatory

HAWC Collaboration, A. Albert, R. Alfaro +59

The close location of the HAWC observatory to the largest volcano in Mexico allows to perform a search for neutrino-induced horizontal muon and tau charged leptons. The section of…

Long-term spectra of the blazars Mrk 421 and Mrk 501 at TeV energies seen by HAWC

A. Albert, R. Alfaro, C. Alvarez +75

The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory surveys the very high energy sky in the 300 GeV to TeV energy range. HAWC has detected two blazars above …

Interplanetary magnetic flux rope observed at ground level by HAWC

S. Akiyama, R. Alfaro, C. Alvarez +59

We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…

HAWC Search for High-Mass Microquasars

HAWC Collaboration, A. Albert, R. Alfaro +87

Microquasars with high-mass companion stars are promising very-high-energy (VHE; 0.1-100 TeV) gamma-ray emitters, but their behaviors above 10 TeV are poorly known. Using the High…

Probing the Sea of Cosmic Rays by Measuring Gamma-Ray Emission from Passive Giant Molecular Clouds with HAWC

A. Albert, R. Alfaro, C. Alvarez +87

The study of high-energy gamma rays from passive Giant Molecular Clouds (GMCs) in our Galaxy is an indirect way to characterize and probe the paradigm of the "sea" of cosmic rays i…
