HAWC Study of the Ultra-High-Energy Spectrum of MGRO J1908+06
HAWC Collaboration, A. Albert, R. Alfaro +97
We report TeV gamma-ray observations of the ultra-high-energy source MGRO J1908+06 using data from the High Altitude Water Cherenkov (HAWC) Observatory. This source is one of the h…
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…
TeV emission of Galactic plane sources with HAWC and H.E.S.S
H. Abdalla, F. Aharonian, F. Ait Benkhali +318
The High Altitude Water Cherenkov (HAWC) observatory and the High Energy Stereoscopic System (H.E.S.S.) are two leading instruments in the ground-based very-high-energy gamma-ray d…
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 …
HAWC observations of the acceleration of very-high-energy cosmic rays in the Cygnus Cocoon
A. U. Abeysekara, A. Albert, R. Alfaro +98
Cosmic rays with energies up to a few PeV are known to be accelerated within the Milky Way. Traditionally, it has been presumed that supernova remnants were the main source of very…
Spectrum and Morphology of the Very-High-Energy Source HAWC J2019+368
HAWC Collaboration, A. Albert, R. Alfaro +80
The MGRO J2019+37 region is one of the brightest sources in the sky at TeV energies. It was detected in the 2 year HAWC catalog as 2HWC J2019+367 and here we present a detailed stu…
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…
Evidence that Ultra-High-Energy Gamma Rays are a Universal Feature Near Powerful Pulsars
HAWC Collaboration, A. Albert, R. Alfaro +97
The highest-energy known gamma-ray sources are all located within 0.5 degrees of extremely powerful pulsars. This raises the question of whether ultra-high-energy (UHE; 56 TeV)…
