A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live-time in 2007. No excess...
A Search for Three and Four Point Correlation in HiRes Stereo Data (2009)
Abbasi, R., Collaboration, For The HiRes
In this paper we investigate the possible existence of multi-point correlation in the arrival direction of the UHECR events detected by the High Resolution Fly's Eye (HiRes) stereo detector....
Search for point sources of high energy neutrinos with final data from AMANDA-II (2009)
Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Ryckbosch, Dirk, ...
We present a search for point sources of high energy neutrinos using 3.8 yr of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selection criteria designed...
The IceCube data acquisition system: Signal capture, digitization, and timestamping (2009)
Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Feusels, Tom, ...
IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules...
SOLAR ENERGETIC PARTICLE SPECTRUM ON 2006 DECEMBER 13 DETERMINED BY IceTop (2008)
Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Ryckbosch, Dirk, Van Overloop, Arne
On 2006 December 13 the IceTop air shower array at the South Pole detected a major solar particle event. By numerically simulating the response of the IceTop tanks, which are thick Cerenkov detectors...
Air fluorescence measurements in the spectral range 300-420 nm using a 28.5 GeV electron beam (2007)
Abbasi, R., Abu-Zayyad, T., Belov, K., Belz, J., Cao, Z., Dalton, M., ...
Measurements are reported of the yield and spectrum of fluorescence, excited by a 28.5 GeV electron beam, in air at a range of pressures of interest to ultra-high energy cosmic ray detectors. The...
Alternative Methods to Finding Patterns in HiRes Stereo Data (2007)
In this paper Ultra High Energy Cosmic Rays UHECRs data observed by the HiRes fluorescence detector in stereo mode is analyzed to search for events in the sky with an arrival direction lying on a...
A framework for inter-society communication in agents (2003)
R. Abbasi, F. Mitchell, S. Greenwood
Abstract. Normally a society of agents is developed to cope with and solve a particular set of problems or to achieve some particular goals and objectives. Different people, organizations and groups...
