Constraining the Photon Intensity of Extragalactic Background Light with the HAWC Observatory for the Blazar Mrk 421

R. Alfaro, C. Alvarez, A. Andrés +79

The blazar Mrk 421 exhibits rapid variability over a wide range of timescales. Spectral differences have been observed during the different emission states of Mrk 421. During the h…

Search for joint multimessenger signals from potential galactic cosmic-ray accelerators with HAWC and IceCube

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +489

The origin of high-energy galactic cosmic rays is yet to be understood, but some galactic cosmic-ray accelerators can accelerate cosmic rays up to PeV energies. The high-energy cos…

A Contribution of the HAWC Observatory to the TeV era in the High Energy Gamma-Ray Astrophysics: The case of the TeV-Halos

Ramiro Torres-Escobedo, Hao Zhou, Eduardo de la Fuente +130

We present a short overview of the TeV-Halos objects as a discovery and a relevant contribution of the High Altitude Water Čerenkov (HAWC) observatory to TeV astrophysics. We discu…

Searching for TeV Dark Matter in Irregular dwarf galaxies with HAWC Observatory

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +69

We present the results of dark matter (DM) searches in a sample of 31 dwarf irregular (dIrr) galaxies within the field of view of the HAWC Observatory. dIrr galaxies are DM dominat…

HAWC Detection of a TeV Halo Candidate Surrounding a Radio-quiet pulsar

A. Albert, R. Alfaro, J. C. Arteaga-Velázquez +59

Extended very-high-energy (VHE; 0.1-100 TeV) -ray emission has been observed around several middle-aged pulsars and referred to as ``TeV halos". Their formation mechanism remain…

High Altitude characterization of the Hunga Pressure Wave with Cosmic Rays by the HAWC Observatory

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +64

High-energy cosmic rays that hit the Earth can be used to study large-scale atmospheric perturbations. After a first interaction in the upper parts of the atmosphere, cosmic rays p…

A measurement of the proton plus helium spectrum of cosmic rays in the TeV region with HAWC

HAWC Collaboration, A. Albert, R. Alfaro +74

HAWC is an air-shower detector designed to study TeV gamma and cosmic rays. The observatory is composed of a array of water Cherenkov tanks ( deep x…

Limits on the Diffuse Gamma-Ray Background above 10 TeV with HAWC

HAWC Collaboration, A. Albert, R. Alfaro +87

The high-energy Diffuse Gamma-Ray Background (DGRB) is expected to be produced by unresolved isotropically distributed astrophysical objects, potentially including dark matter anni…

Spectrum and Morphology of the Very-High-Energy Source HAWC J2019+368

HAWC Collaboration, A. Albert, R. Alfaro +80

The MGRO J2019+37 region is one of the brightest sources in the sky at TeV energies. It was detected in the 2 year HAWC catalog as 2HWC J2019+367 and here we present a detailed stu…

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)…
