PSR J2021+4026 in the Gamma Cygni region: the first variable gamma-ray pulsar seen by the Fermi LAT
LAT collaboration
Long-term monitoring of PSR J2021+4026 in the heart of the Cygnus region with the Fermi Large Area Telescope (LAT) unveiled a sudden decrease in flux above 100 MeV over a time scal…
Energy Spectrum of Ultra-High Energy Cosmic Rays Observed with the Telescope Array Using a Hybrid Technique
T. Abu-Zayyad, R. Aida, M. Allen +141
We measure the spectrum of cosmic rays with energies greater than eV with the Fluorescence Detectors (FDs) and the Surface Detectors (SDs) of the Telescope Array Experi…
The Energy Spectrum of Ultra-High-Energy Cosmic Rays Measured by the Telescope Array FADC Fluorescence Detectors in Monocular Mode
The Telescope Array Collaboration, T. Abu-Zayyad, R. Aida +141
We present a measurement of the energy spectrum of ultra-high-energy cosmic rays performed by the Telescope Array experiment using monocular observations from its two new FADC-base…
Upper limit on the flux of photons with energies above 10^19 eV using the Telescope Array surface detector
T. Abu-Zayyad, R. Aida, M. Allen +138
We search for ultra-high energy photons by analyzing geometrical properties of shower fronts of events registered by the Telescope Array surface detector. By making use of an event…
Detection of the Characteristic Pion-Decay Signature in Supernova Remnants
LAT collaboration, M. Ackermann, M. Ajello +167
Cosmic rays are particles (mostly protons) accelerated to relativistic speeds. Despite wide agreement that supernova remnants (SNRs) are the sources of galactic cosmic rays, unequi…
