Study of Ultra-High Energy Cosmic Ray Composition Using Telescope Array's Middle Drum Detector and Surface Array in Hybrid Mode
R. U. Abbasi, M. Abe, T. Abu-Zayyad +123
Previous measurements of the composition of Ultra-High Energy Cosmic Rays(UHECRs) made by the High Resolution Fly's Eye(HiRes) and Pierre Auger Observatory(PAO) are seemingly contr…
A Northern Sky Survey for Point-Like Sources of EeV Neutral Particles with the Telescope Array Experiment
R. U. Abbasi, M. Abe, T. Abu-Zayyad +122
We report on the search for steady point-like sources of neutral particles around 10 eV between 2008 May and 2013 May with the scintillator surface detector of the Telescope…
Indications of Intermediate-Scale Anisotropy of Cosmic Rays with Energy Greater Than 57 EeV in the Northern Sky Measured with the Surface Detector of the Telescope Array Experiment
The Telescope Array Collaboration, R. U. Abbasi, M. Abe +123
We have searched for intermediate-scale anisotropy in the arrival directions of ultrahigh-energy cosmic rays with energies above 57~EeV in the northern sky using data collected ove…
Recent results from Telescope Array
Takeshi Okuda
The Telescope Array (TA) observatory, located in midwest Utah, USA, is designed to detect ultra high energy cosmic rays whose energy is greater than 1 EeV. TA mainly consists of tw…
The jet and arc molecular clouds toward Westerlund 2, RCW 49, and HESS J1023-575; 12CO and 13CO (J=2-1 and J=1-0) observations with NANTEN2 and Mopra Telescope
N. Furukawa, A. Ohama, T. Fukuda +20
We have made new CO observations of two molecular clouds, which we call "jet" and "arc" clouds, toward the stellar cluster Westerlund 2 and the TeV gamma-ray source HESS J1023-575.…
Fermi LAT detection of two high Galactic latitude gamma-ray sources, Fermi J1049.7+0435 and J1103.2+1145
Masaki Nishimichi, Takeshi Okuda, Masaki Mori +2
The Second Fermi LAT source catalog (Nolan et al. 2012) includes as many as 1,873 sources, but initial attempts to identify counterparts at other wavelengths resulted in 575 source…
