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…

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)…

Evidence of 200 TeV photons from HAWC J1825-134

A. Albert, R. Alfaro, C. Alvarez +81

The Earth is bombarded by ultra-relativistic particles, known as cosmic rays (CRs). CRs with energies up to a few PeV (=10 eV), the knee in the particle spectrum, are believ…

A survey of active galaxies at TeV photon energies with the HAWC gamma-ray observatory

A. Albert, C. Alvarez, J. R. Angeles Camacho +86

The High Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) continuously detects TeV photons and particles within its large field-of-view, accumulating every day a deeper exposu…
