Investigating a TeV-Halo Candidate around PSR J1928+1746 with HAWC
The HAWC Collaboration, R. Alfaro, C. Alvarez +94
We present an updated High-Altitude Water Cherenkov (HAWC) analysis of the crowded Galactic-plane area near PSR J1928+1746, which was previously linked to the extended source 3HWC…
Search for TeV emission from spider millisecond pulsars with HAWC
R. Alfaro, E. Anita-Rangel, M. Araya +90
Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…
A Multi-messenger Search for Ultra-high-energy Gamma Rays in Coincidence with Neutrinos
R. Alfaro, C. Alvarez, A. Andrés +101
The last five years have shown us that ultra-high-energy (UHE; 100 TeV) gamma-ray sources are ubiquitous, but the nature of these sources remain highly uncertain. UHE gamma rays…
HAWC Study on the Ultra-High-Energy Gamma-Ray Emissions from the Pulsar Wind Nebula G32.64+0.53
R. Alfaro, C. Alvarez, E. Anita-Rangel +91
Multi-TeV gamma-ray emission around eHWC J1850+001 (a source from the first HAWC catalog of gamma-ray sources emitting above 56 TeV) is spatially coincident with the pulsar wind ne…
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 contribution of winds of star clusters to the Galactic cosmic-ray population
Giada Peron, Sabrina Casanova, Stefano Gabici +2
Cosmic rays are energetic nuclei that permeate the entire Galactic disk. Their existence requires the presence of powerful particle accelerators. While Galactic supernova explosion…
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…
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…
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…
Constraining the Origin of Local Positrons with HAWC TeV Gamma-Ray Observations of Two Nearby Pulsar Wind Nebulae
F. Salesa Greus, S. Casanova, B. Dingus +2
The HAWC Gamma-Ray Observatory has reported the discovery of TeV gamma-ray emission extending several degrees around the positions of Geminga and B0656+14 pulsars. Assuming these g…
