A New Measurement of Cosmic Ray Composition at the Knee
, 1997 The Dual Imaging Cerenkov Experiment (DICE) was designed and operated for making elemental composition measurements of cosmic rays near the knee of the spectrum at several PeV.

Beaming effects in GRBs and orphan afterglows
, 2004 The overall dynamical evolution and radiation mechanism of $\gamma$-ray burst jets are briefly introduced. Various interesting topics concerning beaming in $\gamma$-ray bursts are discussed, including jet structures, orphan afterglows and cylindrical ...

On the Very-High-Energy Gamma Ray Spectra from Typical Supernovae Remnants [PDF]
, 2008 Recently measured VHE gamma ray spectra from supernovae remnants (SNRs) are best fit by power laws with an exponential cutoff. But this feature does not occur at the `knee-equivalent' energy at which VHE gamma ray spectra are expected to reflect the ...

, 2011 We derive lower bounds on intergalactic magnetic fields (IGMFs) from upper limits on the pair echo emission from the blazar Mrk 501, that is, delayed GeV emission from secondary $e^{-}e^{+}$ pairs produced via interactions of primary TeV gamma rays with ...

Probing Intergalactic Magnetic Fields in the GLAST Era through Pair Echo Emission from TeV Blazars
, 2008 More than a dozen blazars are known to be emitters of multi-TeV gamma rays, often with strong and rapid flaring activity. By interacting with photons of the cosmic microwave and infrared backgrounds, these gamma rays inevitably produce electron-positron ...
