The Fourth HAWC Catalog of Very-High-Energy Gamma-Ray Sources
R. Alfaro, C. Alvarez, E. Anita-Rangel +87
We present an updated catalog of TeV gamma-ray sources based on the fifth pass of data from the High-Altitude Water Cherenkov (HAWC) Observatory. This release benefits from improve…
Absence of TeV halos around millisecond pulsars
A. U. Abeysekara, R. Alfaro, C. Alvarez +82
TeV halos are extended very-high-energy (VHE; 0.1-100 TeV) gamma-ray emission around middle-aged pulsars. So far they have only been found around isolated pulsars, but it has been…
Testing the Molecular Cloud Paradigm for Ultra-High-Energy Gamma Ray Emission from the Direction of SNR G106.3+2.7
R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +87
Supernova remnants (SNRs) are believed to be capable of accelerating cosmic rays (CRs) to PeV energies. SNR G106.3+2.7 is a prime PeVatron candidate. It is formed by a head region,…
Observation of the Galactic Center PeVatron Beyond 100 TeV with HAWC
A. Albert, R. Alfaro, C. Alvarez +99
We report an observation of ultra-high energy (UHE) gamma rays from the Galactic Center region, using seven years of data collected by the High-Altitude Water Cherenkov (HAWC) Obse…
Analysis of the Emission and Morphology of the Pulsar Wind Nebula Candidate HAWC J2031+415
R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +78
The first TeV gamma-ray source with no lower energy counterparts, TeV J2032+4130, was discovered by HEGRA. It appears in the third HAWC catalog as 3HWC J2031+415 and it is a bright…
Performance of the HAWC Observatory and TeV Gamma-Ray Measurements of the Crab Nebula with Improved Extensive Air Shower Reconstruction Algorithms
A . Albert, R. Alfaro, C. Alvarez +90
The High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory located on the side of the Sierra Negra volcano in Mexico, has been fully operational since 2015. The HAWC collaborat…
Comparing HAWC blazars light curves with different data reconstruction versions
J. A. García-González, M. M. González
We present a comparison of the flux normalization of HAWC sources using 17 months of data that was processed using two different versions of the official data reconstruction used f…
The High-Altitude Water Cherenkov (HAWC) Observatory in México: The Primary Detector
A. U. Abeysekara, A. Albert, R. Alfaro +140
The High-Altitude Water Cherenkov (HAWC) observatory is a second-generation continuously operated, wide field-of-view, TeV gamma-ray observatory. The HAWC observatory and its analy…
Detailed Analysis of the TeV γ-Ray Sources 3HWC J1928+178, 3HWC J1930+188, and the New Source HAWC J1932+192
A. Albert, R. Alfaro, C. Alvarez +91
The latest High Altitude Water Cherenkov (HAWC) point-like source catalog up to 56 TeV reported the detection of two sources in the region of the Galactic plane at galactic longitu…
Gamma/Hadron Separation with the HAWC Observatory
R. Alfaro, C. Alvarez, J. D. Álvarez +90
The High Altitude Water Cherenkov (HAWC) gamma-ray observatory observes atmospheric showers produced by incident gamma rays and cosmic rays with energy from 300 GeV to more than 10…
Probing the extragalactic mid-infrared background with HAWC
Mateo Fernandez Alonso
The extragalactic background light (EBL) contains all the radiation emitted by nuclear and accretion processes in stars and compact objects since the epoch of recombination. Measur…
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…
Horizontal muon track identification with neural networks in HAWC
J. R. Angeles Camacho, H. León Vargas
Nowadays the implementation of artificial neural networks in high-energy physics has obtained excellent results on improving signal detection. In this work we propose to use neural…
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…
HAWC Search for High-Mass Microquasars
HAWC Collaboration, A. Albert, R. Alfaro +87
Microquasars with high-mass companion stars are promising very-high-energy (VHE; 0.1-100 TeV) gamma-ray emitters, but their behaviors above 10 TeV are poorly known. Using the High…
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…
