The balloon-borne cosmic-ray experiment CREAM-I (Cosmic-Ray Energetics And Mass) completed a successful 42-day flight during the 2004-2005 NASA/NSF/NSBF Antarctic expedition. CREAM-I combines an imaging calorimeter with charge detectors and a precision transition radiation detector (TRD). The TRD component of CREAM-I is targeted at measuring the energy of cosmic-ray particles with charges grea ... More

This talk present preliminary results for the time-dependent cosmic-ray propagation in the Galaxy by a fully 3-dimensional Monte Carlo simulation. The distribution of cosmic-rays (both protons and helium nuclei) in the Galaxy is studied on various spatial scales for both constant and variable cosmic-ray sources. The continuous diffuse gamma-ray emission produced by cosmic-rays during the ... More

The propagation of UHECRs is affected by the intergalactic magnetic field that was produced during the course of the large scale structure formation of the universe. Adopting a novel model based on turbulent dynamo, the strength of the intergalactic magnetic field is estimated from local dynamic properties of the gas flows in hydrodynamic simulations of a concordance LCDM universe. The direc ... More

Different locations in the galaxy are unequally participating into the production of elements and isotopes observed in the solar system. In this work, we present a model that includes spatial dimensions as a basic element. The backward stochastic solution introduced in this paper will allow us to determine the abundance of each nucleus at certain energy and a single location in the galax ... More

After successful recovery of the first CREAM (Cosmic Ray Energetics And Mass) instrument during the 2004/5 Antarctic campaign, the calorimeter was refurbished for the third launch, planned for December 2007. In this CREAM-III calorimeter, the optics were replaced with multi-clad fiber ribbons to enhance the light signal. New readout electronics boards reduce noise even further than the ... More

Many experimental results around and above the energies where the solar modulation affects cosmic ion fluxes were quantified, debated and conceptualized using leaky box models. These models basically exploit the notion of equilibrium between creation and destruction processes of cosmic ions in an undifferentiated arbitrary volume representing the Galaxy, ignoring the galactic magnetic fi ...
