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…
Investigating IceCube Neutrino Alerts with the HAWC -Ray Observatory
The HAWC Collaboration, R. Alfaro, C. Alvarez +95
Neutrino emission from astrophysical sources has long been considered a signature of cosmic-ray acceleration. The IceCube neutrino observatory has observed a diffuse flux of TeV-Pe…
Improved Heavy Dark Matter Annihilation Search from Dwarf Galaxies with HAWC
A. Albert, R. Alfaro, C. Alvarez +103
Understanding dark matter's elusive nature is crucial for the framework of particle physics and expanding the Standard Model. This analysis utilizes the High Altitude Water Cherenk…
Microphysical Parameter Variation in GRB Stratified Afterglows and Closure Relations: from sub-GeV to TeV Observations
Nissim Fraija, Maria G. Dainotti, Boris Betancourt Kamenetskaia +2
Gamma-ray bursts (GRBs) are one of the most exciting sources that offer valuable opportunities for investigating the evolution of energy fraction given to magnetic fields and parti…
Constraints on the very high energy gamma-ray emission from short GRBs with HAWC
A. Albert, R. Alfaro, C. Alvarez +87
Many gamma-ray bursts (GRBs) have been observed from radio wavelengths, and a few at very-high energies (VHEs, > 100GeV). The HAWC gamma-ray observatory is well suited to study tra…
TeV emission of Galactic plane sources with HAWC and H.E.S.S
H. Abdalla, F. Aharonian, F. Ait Benkhali +318
The High Altitude Water Cherenkov (HAWC) observatory and the High Energy Stereoscopic System (H.E.S.S.) are two leading instruments in the ground-based very-high-energy gamma-ray d…
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)…
Multimessenger Gamma-Ray and Neutrino Coincidence Alerts using HAWC and IceCube sub-threshold Data
H. A. Ayala Solares, S. Coutu, J. J. DeLaunay +446
The High Altitude Water Cherenkov (HAWC) and IceCube observatories, through the Astrophysical Multimessenger Observatory Network (AMON) framework, have developed a multimessenger j…
Electron-positron pair plasma in TXS 0506+056 and the "neutrino flare" in 2014-2015
Nissim Fraija, Edilberto Aguilar-Ruiz, Antonio Galván-Gámez
The detection of a long flaring activity from blazar TXS 0506+056 in temporal and spatial coincidence with the energetic neutrino IceCube-170922A provided evidence about the photo-…
HAWC Contributions to the 36th International Cosmic Ray Conference (ICRC2019)
A. U. Abeysekara, A. Albert, R. Alfaro +127
List of proceedings from the HAWC Collaboration presented at the 36th International Cosmic Ray Conference, 24 July - 1 August 2019, Madison, Wisconsin, USA.
All-Sky Measurement of the Anisotropy of Cosmic Rays at 10 TeV and Mapping of the Local Interstellar Magnetic Field
HAWC Collaboration, A. U. Abeysekara, R. Alfaro +400
We present the first full-sky analysis of the cosmic ray arrival direction distribution with data collected by the HAWC and IceCube observatories in the Northern and Southern hemis…
Constraining the Ratio in TeV Cosmic Rays with Observations of the Moon Shadow by HAWC
A. U. Abeysekara, A. Albert, R. Alfaro +98
An indirect measurement of the antiproton flux in cosmic rays is possible as the particles undergo deflection by the geomagnetic field. This effect can be measured by studying the…
Long-term optical polarization variability and multiwavelength analysis of Blazar Mrk 421
Nissim Fraija, Erika Benítez, David Hiriart +8
The results of 8-year R-band photopolarimetric data of blazar Mrk 421 collected from February 2008 to May 2016 are presented, along with extensive multiwavelength observations cove…
