Long-term spectra of the blazars Mrk 421 and Mrk 501 at TeV energies seen by HAWC
A. Albert, R. Alfaro, C. Alvarez +75
The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory surveys the very high energy sky in the 300 GeV to TeV energy range. HAWC has detected two blazars above $11Ï…
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…
Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth
A. U. Abeysekara, A. Albert, R. Alfaro +113
The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…
VAMOS: a Pathfinder for the HAWC Gamma-Ray Observatory
A. U. Abeysekara, R. Alfaro, C. Alvarez +133
VAMOS was a prototype detector built in 2011 at an altitude of 4100m a.s.l. in the state of Puebla, Mexico. The aim of VAMOS was to finalize the design, construction techniques and…
-ray Emission from Classical Nova V392 Per: Measurements from Fermi and HAWC
A. Albert, R. Alfaro, C. Alvarez +84
This paper reports on the -ray properties of the 2018 Galactic nova V392 Per, spanning photon energies 0.1 GeV to 100 TeV by combining observations from the Fermi Gamma-r…
