The HAWC ultra-high-energy gamma-ray map with more than 5 years of data
Kelly Malone, José Andrés García González, Patrick Harding
In 2020, the HAWC Collaboration presented the first catalog of gamma-ray sources emitting above 56 TeV and 100 TeV. With nine sources detected, this was the highest-energy source c…
Galactic Gamma-Ray Diffuse Emission at TeV energies with HAWC Data
R. Alfaro, C. Alvarez, J. C. Arteaga-Velazquez +77
The Galactic gamma-ray diffuse emission (GDE) is emitted by cosmic rays (CRs), ultra-relativistic protons and electrons, interacting with gas and electromagnetic radiation fields i…
An updated survey of Active Galaxies with the HAWC gamma-ray observatory
Fernando Ureña-Mena, Alberto Carramiñana, Daniel Rosa-González +2
We present an update of the survey of Active Galaxies with the High Altitude Water Cherenkov (HAWC) gamma-ray observatory. This work adds 567 days of HAWC data to the previously pu…
Study of the long-term Very High Energy emission of the blazars 1ES 1215+3031 and VER J0521+211 with the HAWC gamma-ray observatory
Fernando Ureña-Mena, Alberto Carramiñana, Anna Lia Longinotti +2
Blazars are the most abundant type of extragalactic gamma-ray source, usually presenting high variability across the electromagnetic spectrum. Their Very High Energy (VHE, above 0.…
Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749
T. Wach, A. M. W. Mitchell, V. Joshi +1
HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind neb…
Modelling of highly extended Gamma-ray emission around the Geminga Pulsar as detected with H.E.S.S
A. M. W. Mitchell, S. Caroff
Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar has been detected…
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…
The all-particle cosmic ray energy spectrum measured with HAWC
J. A. Morales-Soto, J. C. Arteaga-Velázquez
Thanks to recent technological development, a new generation of cosmic ray experiments have been developed with more sensitivity to study these particles in the primary energy inte…
The young massive stellar cluster Westerlund 1 in rays as seen with H.E.S.S
Lars Mohrmann, Andreas Specovius, Romed Rauth +2
Massive stellar clusters have recently been hypothesised as candidates for the acceleration of hadronic cosmic rays up to PeV energies. Previously, the H.E.S.S. Collaboration has r…
Detection of extended TeV emission around the Geminga pulsar with H.E.S.S
A. M. W. Mitchell, S. Caroff, J. Hinton +1
Highly extended gamma-ray emission around the Geminga pulsar was discovered by Milagro and verified by HAWC. Despite many observations with Imaging Atmospheric Cherenkov Telescopes…
Detection of new Extreme BL Lac objects with H.E.S.S. and Swift XRT
Mathieu de Bony de Lavergne, Tomas Bylund, Manuel Meyer +2
Extreme high synchrotron peaked blazars (EHBLs) are amongst the most powerful accelerators found in nature. Usually the synchrotron peak frequency of an EHBL is above Hz…
Monitoring the radio galaxy M87 with HAWC
T. Capistrán, D. Avila Rojas, M. M. González +2
Studies of radio galaxies at TeV energies are fascinating because their jets are misaligned concerning our sightline. Thus, it provides us with a unique opportunity to study the st…
Use of Machine Learning for gamma/hadron separation with HAWC
T. Capistrán, K. L. Fan, J. T. Linnemann +3
Background showers triggered by hadrons represent over 99.9% of all particles arriving at ground-based gamma-ray observatories. An important stage in the data analysis of these obs…
3HWC: The Third HAWC Catalog of Very-High-Energy Gamma-ray Sources
A. Albert, R. Alfaro, C. Alvarez +104
We present a new catalog of TeV gamma-ray sources using 1523 days of data from the High Altitude Water Cherenkov (HAWC) observatory. The catalog represents the most sensitive surve…
Combined Dark Matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, HESS, MAGIC and VERITAS
Louise Oakes, Celine Armand, Eric Charles +13
The search for Dark Matter (DM) has great potential to reveal physics beyond the Standard Model. As such, searches for evidence of DM particles are being carried out using a wide r…

A. U. Abeysekara, R. Alfaro, C. Alvarez +98
After two years of operation, the High-Altitude Water Cherenkov (HAWC) Observatory has analyzed the TeV cosmic-ray sky over an energy range between and TeV. The HAWC d…
