Measurements of Cosmic-Ray Hydrogen and Helium Isotopes with the PAMELA experiment

O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +56

The cosmic-ray hydrogen and helium (H, H, He, He) isotopic composition has been measured with the satellite-borne experiment PAMELA, which was launched into low-Ear…

4.5 years multi-wavelength observations of Mrk 421 during the ARGO-YBJ and Fermi common operation time

B. Bartoli, P. Bernardini, X. J. Bi +68

We report on the extensive multi-wavelength observations of the blazar Markarian 421 (Mrk 421) covering radio to gamma-rays, during the 4.5 year period of ARGO-YBJ and Fermi common…

Search for anisotropies in cosmic-ray positrons detected by the PAMELA experiment

O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +57

The PAMELA detector was launched on board of the Russian Resurs-DK1 satellite on June 15, 2006. Data collected during the first four years have been used to search for large-scale…

Optical and X-ray early follow-up of ANTARES neutrino alerts

S. Adrian-Martinez, M. Ageron, A. Albert +137

High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. Even with the recent detection of extr…

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…

An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462

Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…

The emission of Gamma Ray Bursts as a test-bed for modified gravity

Salvatore Capozziello, Gaetano Lambiase

The extreme physical conditions of Gamma Ray Bursts can constitute a useful observational laboratory to test theories of gravity where very high curvature regimes are involved. Her…

Search for GeV Gamma Ray Bursts with the ARGO-YBJ Detector: Summary of Eight Years of Observations

B. Bartoli, P. Bernardini, X. J. Bi +78

The search for Gamma Ray Burst (GRB) emission in the energy range 1-100 GeV in coincidence with the satellite detection has been carried out using the Astrophysical Radiation with…

The Knee of the Cosmic Hydrogen and Helium Spectrum below 1 PeV Measured by ARGO-YBJ and a Cherenkov Telescope of LHAASO

B. Bartoli, P. Bernardini, X. J. Bi +93

The measurement of cosmic ray energy spectra, in particular for individual species, is an essential approach in finding their origin. Locating the "knees" of the spectra is an impo…

ANTARES Constrains a Blazar Origin of Two IceCube PeV Neutrino Events

ANTARES Collaboration, S. Adrián-Martínez, A. Albert +166

The source(s) of the neutrino excess reported by the IceCube Collaboration is unknown. The TANAMI Collaboration recently reported on the multiwavelength emission of six bright, var…
