Study of the Very High Energy emission of M87 through its broadband spectral energy distribution

HAWC Collaboration, R. Alfaro, C. Alvarez +63

The radio galaxy M87 is the central dominant galaxy of the Virgo Cluster. Very High Energy (VHE, TeV) emission, from M87 has been detected by Imaging Air Cherenkov Tel…

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…

Particle Acceleration in the Cygnus Superbubble

B. Hona

The Cygnus Cocoon is the first gamma-ray superbubble powered by a massive stellar association, the OB2 association. It was postulated that the combined effects of the stellar winds…

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…

Horizontal muon track identification with neural networks in HAWC

J. R. Angeles Camacho, H. León Vargas

Nowadays the implementation of artificial neural networks in high-energy physics has obtained excellent results on improving signal detection. In this work we propose to use neural…

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…

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…

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)…
