Very high energy neutrino expectation from Fanaroff-Riley I sources
A. Marinelli, N. Fraija
Fanaroff-Riley I radiogalaxies have been observed in TeV gamma-rays during the last decades. The origin of the emission processes related with this energy band is still under debat…
TeV -ray fluxes from the long campaigns on Mrk421 as constraints on the emission of TeV-PeV Neutrinos and UHECRs
Nissim Fraija, Antonio Marinelli
Long TeV -ray campaigns have been carried out to study the spectrum, variability and duty cycle of the BL Lac object Markarian 421. These campaigns have given some evidence of t…
The Hadronic Picture of the Radiogalaxy M87
A. Marinelli, N. Fraija, B. Patricelli
Very high energy gamma-ray emission of Fanaroff-Riley I objects is not univocally explained by a single emission model. Leptonic models with one and multi-zone emission regions, oc…
Search for gamma-rays from the unusually bright GRB 130427A with the HAWC Gamma-ray Observatory
The HAWC collaboration, A. U. Abeysekara, R. Alfaro +90
The first limits on the prompt emission from the long gamma-ray burst (GRB) 130427A in the energy band are reported. GRB 130427A was the most powerful b…
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…
Observation of Small-scale Anisotropy in the Arrival Direction Distribution of TeV Cosmic Rays with HAWC
A. U. Abeysekara, R. Alfaro, C. Alvarez +96
The High-Altitude Water Cherenkov (HAWC) Observatory is sensitive to gamma rays and charged cosmic rays at TeV energies. The detector is still under construction, but data acquisit…
Milagro Limits and HAWC Sensitivity for the Rate-Density of Evaporating Primordial Black Holes
A. A. Abdo, A. U. Abeysekara, R. Alfaro +118
Primordial Black Holes (PBHs) are gravitationally collapsed objects that may have been created by density fluctuations in the early universe and could have arbitrarily small masses…
Scientific Verification of the High Altitude Water Cherenkov observatory
Antonio Marinelli, Kathryne Sparks, Ruben Alfaro +3
The High Altitude Water Cherenkov (HAWC) observatory is a TeV gamma-ray and cosmic-ray detector currently under construction at an altitude of 4100 m close to volcano Sierra Negra…
The Sensitivity of HAWC to High-Mass Dark Matter Annihilations
A. U. Abeysekara, R. Alfaro, C. Alvarez +101
The High Altitude Water Cherenkov (HAWC) observatory is a wide field-of-view detector sensitive to gamma rays of 100 GeV to a few hundred TeV. Located in central Mexico at 19 degre…
Estimation of the TeV gamma-ray duty cycle of Mrk 421 with Milagro
B. Patricelli, M. M. González, N. Fraija +1
The blazar Markarian 421 (Mrk 421) is one of the brightest sources in the extragalactic X-ray/TeV sky. It is also one of the fastest varying TeV -ray sources, showing flaring ac…
Study of TeV variability of Mrk 421 from 3 years of monitoring with the Milagro Observatory
B. Patricelli, M. M. González, N. Fraija +1
The Milagro experiment was a TeV gamma-ray observatory designed to continuously monitor the overhead sky in the 0.1-100 TeV energy range. It operated from 2000 and 2008 and was cha…
Estimation of the TeV gamma-ray duty cycle of Mrk 421 with the Milagro observatory
B. Patricelli, M. M. González, N. Fraija +1
Markarian 421 (Mrk 421) is one the brightest and closest (z=0.031) blazars known (de Vaucouleurs et al 1991). It is also one of the fastest varying TeV -ray sources, with a flar…
The Study of TeV Variability and Duty Cycle of Mrk 421 from 3 Years of Observations with the Milagro Observatory
A. A. Abdo, A. U. Abeysekara, B. T. Allen +36
TeV flaring activity with time scales as short as tens of minutes and an orphan TeV flare have been observed from the blazar Markarian 421 (Mrk 421). The TeV emission from Mrk 421…
