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…
TeV Analysis of a Source Rich Region with HAWC Observatory: Is HESS J1809-193 a Potential Hadronic PeVatron?
A. Albert, R. Alfaro, C. Alvarez +79
HESS J1809-193 is an unidentified TeV source, first detected by the High Energy Stereoscopic System (H.E.S.S.) Collaboration. The emission originates in a source-rich region that i…
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…
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…
Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…
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…
