Detection of extended X-ray emission around the PeVatron microquasar V4641 Sgr with XRISM

Hiromasa Suzuki, Naomi Tsuji, Yoshiaki Kanemaru +26

A recent report on the detection of very-high-energy gamma rays from V4641 Sagittarii (V4641 Sgr) up to ~0.8 peta-electronvolt has made it the second confirmed "PeVatron" microquas…

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.…

VERITAS and HAWC observations of unidentified source LHAASO J2108+5157

Sajan Kumar, Michael Martin, Xiaojie Wang

Understanding the complete nature of Galactic sources that accelerate cosmic rays up to eV energy (Galactic PeVatrons) is still an unsolved problem in high-energy astroph…

An optimized search for dark matter in the galactic halo with HAWC

A. Albert, R. Alfaro, C. Alvarez +63

The Galactic Halo is a key target for indirect dark matter detection. The High Altitude Water Cherenkov (HAWC) observatory is a high-energy (~300 GeV to >100 TeV) gamma-ray detecto…

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Celine Armand, Eric Charles, Mattia di Mauro +13

Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…

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…

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…

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…
