PRECISE COSMIC RAYS MEASUREMENTS WITH PAMELA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The PAMELA experiment was launched on board the Resurs-DK1 satellite on June 15th 2006. The apparatus was designed to conduct precision studies of charged cosmic radiation over a wide energy range, from tens of MeV up to ...
RADIOACTIVE UHECR ASTRONOMY: CORRELATING GAMMA ANISOTROPY AND NEUTRINO PEV EVENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
UHECR (Ultra High Energy Cosmic Rays) were expected to be protons, to fly straight and to suffer of a GZK (opacity on CMB radiation) cut off. AUGER did suggest on 2007 that such early UHECR anisotropy was compatible with ...
INVESTIGATING THE Ep, i –Eiso CORRELATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The correlation between the spectral peak photon energy, Ep, and the radiated energy or luminosity (i.e., the “Amati relation” and other correlations derived from it) is one of the central and most debated topics in GRB ...
INFLUENCE OF THE RESULTS OF UHECR DETECTION ON THE LHC EXPERIMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The cosmic ray energy region 1015 ÷ 1017TeV corresponds to LHC energies 1 ÷ 14TeV in the center-of-mass system. The results obtained in cosmic rays (CR) in this energy interval can therefore be used for developing new ...
DO WE SEE THE ‘IRON PEAK’?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Recent measurements of the cosmic ray (CR) energy spectrum in the PeV region and above have confirmed the remarkable sharpness of the knee and revealed another structure at about 70PeV which we call the ‘Iron Peak’. The ...
COMPUTATIONAL SCHEMES FOR THE PROPAGATION OF ULTRA HIGH ENERGY COSMIC RAYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We discuss the problem of ultra high energy particles propagation in astrophysical backgrounds. We present two different computational schemes based on kinetic and Monte Carlo approaches. The kinetic approach is an analytical ...
RESULTS FROM LHCF EXPERIMENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The LHCf experiment has taken data in 2009 and 2010 p–p collisions at LHC at √s = 0.9TeV and √s = 7TeV. In this paper the most up-to-date results on the inclusive photon spectra and the π0 spectra measured by LHCf are ...
ULTRAHIGH ENERGY COSMIC RAYS: REVIEW OF THE CURRENT SITUATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We describe the current situation of the data on the highest energy particles in the Universe – the ultrahigh energy cosmic rays. The new results in the field come from the Telescope Array experiment in Utah, U.S.A. For ...
THE MASS COMPOSITION OF ULTRA HIGH ENERGY COSMIC RAYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The status of the Mass Composition measurements of Ultra High Energy Cosmic Rays is presented, with emphasis on the results from the Fluorescence Detector of the Pierre Auger Observatory. Possible consequences of the present ...
MOONLIGHT: A NEW LUNAR LASER RANGING RETROREFLECTOR AND THE LUNAR GEODETIC PRECESSION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Since the 1970s Lunar Laser Ranging (LLR) to the Apollo Cube Corner Retroreflector (CCR) arrays (developed by the University of Maryland, UMD) supplied almost all significant tests of General Relativity (Alley et al., 1970; ...
