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 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…
