Evidence of 200 TeV photons from HAWC J1825-134
A. Albert, R. Alfaro, C. Alvarez +81
The Earth is bombarded by ultra-relativistic particles, known as cosmic rays (CRs). CRs with energies up to a few PeV (=10 eV), the knee in the particle spectrum, are believ…
Observation of a sudden cessation of a very-high-energy gamma-ray flare in PKS 1510-089 with H.E.S.S. and MAGIC in May 2016
H. E. S. S. Collaboration, H. Abdalla, R. Adam +430
The flat spectrum radio quasar (FSRQ) PKS 1510-089 is known for its complex multiwavelength behavior, and is one of only a few FSRQs detected at very high energy (VHE, GeV…
An extreme particle accelerator in the Galactic plane: HESS J1826130
H. E. S. S. Collaboration, H. Abdalla, R. Adam +236
The unidentified very-high-energy (VHE; E 0.1 TeV) -ray source, HESS J1826130, was discovered with the High Energy Stereoscopic System (HESS) in the Galactic plane. The a…
HAWC and Fermi-LAT Detection of Extended Emission from the Unidentified Source 2HWC J2006+341
A. Albert, R. Alfaro, C. Alvarez +71
The discovery of the TeV point source 2HWC J2006+341 was reported in the second HAWC gamma-ray catalog. We present a follow-up study of this source here. The TeV emission is best d…
A survey of active galaxies at TeV photon energies with the HAWC gamma-ray observatory
A. Albert, C. Alvarez, J. R. Angeles Camacho +86
The High Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) continuously detects TeV photons and particles within its large field-of-view, accumulating every day a deeper exposu…
Evidence of Cosmic-Ray Excess from Local Giant Molecular Clouds
Vardan Baghmanyan, Giada Peron, Sabrina Casanova +2
We report the analysis of the Fermi-Large Area Telescope data from six nearby giant molecular clouds (MCs) belonging to the Gould Belt and the Aquila Rift regions. The high statist…
Search for dark matter signals towards a selection of recently-detected DES dwarf galaxy satellites of the Milky Way with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdallah +227
Dwarf spheroidal galaxy satellites of the Milky Way are prime targets for indirect detection of dark matter with gamma rays due to their proximity, high dark matter content and abs…
3HWC: The Third HAWC Catalog of Very-High-Energy Gamma-ray Sources
A. Albert, R. Alfaro, C. Alvarez +104
We present a new catalog of TeV gamma-ray sources using 1523 days of data from the High Altitude Water Cherenkov (HAWC) observatory. The catalog represents the most sensitive surve…
HAWC J2227+610 and its association with G106.3+2.7, a new potential Galactic PeVatron
A. Albert, R. Alfaro, C. Alvarez +97
We present the detection of VHE gamma-ray emission above 100 TeV from HAWC J2227+610 with the HAWC observatory. Combining our observations with previously published results by VERI…
Probing the magnetic field in the GW170817 outflow using H.E.S.S. observations
H. E. S. S. Collaboration, :, H. Abdalla +230
The detection of the first electromagnetic counterpart to the binary neutron star (BNS) merger remnant GW170817 established the connection between short -ray bursts and BNS merg…
Very high energy -ray emission from two blazars of unknown redshift and upper limits on their distance
H. E. S. S. Collaboration, H. Abdalla, R. Adam +225
We report on the detection of very-high-energy (VHE; GeV) -ray emission from the BL Lac objects KUV 00311-1938 and PKS 1440-389 with the High Energy Stereoscopic Syste…
