Probing nuclear rates with Planck and BICEP2

Julien Lesgourgues

Big-bang nucleosynthesis (BBN) relates key cosmological parameters to the primordial abundance of light elements. In this paper, we point out that the recent observations of cosmic microwave background anisotropies by the Planck satellite and by the BICEP2 ...

Probing the origin of cosmic rays with extremely high energy neutrinos using the IceCube Observatory

Matthias Wolf, Mark Tobin, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

We have searched for extremely high energy neutrinos using data taken with the IceCube detector between May 2010 and May 2012. Two neutrino-induced particle shower events with energies around 1 PeV were observed, as reported previously. In this work, we in ...

All-particle cosmic ray energy spectrum measured with 26 IceTop stations

Matthias Wolf, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

We report on a measurement of the cosmic ray energy spectrum with the IceTop air shower array, the surface component of the IceCube Neutrino Observatory at the South Pole. The data used in this analysis were taken between June and October, 2007, with 26 su ...

Observation Of Cosmic-Ray Anisotropy With The Icetop Air Shower Array

Matthias Wolf, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

We report on the observation of anisotropy in the arrival direction distribution of cosmic rays at PeV energies. The analysis is based on data taken between 2009 and 2012 with the IceTop air shower array at the south pole. IceTop, an integral part of the I ...

IceTop: The surface component of IceCube

Matthias Wolf, Xiaoxia Bai, Mathieu Ribordy, Shirit Cohen

IceTop, the surface component of the IceCube Neutrino Observatory at the South Pole, is an air shower array with an area of 1 km(2). The detector allows a detailed exploration of the mass composition of primary cosmic rays in the energy range from about 10 ...

How are small endohedral silicon clusters stabilized?

Anne-Clémence Corminboeuf, Fabrice Avaltroni

Clusters in the (Be, B, C)@Si-n((0,1,2+)) (n = 6-10) series, isoelectronic to Si-n(2-), present multiple symmetric structures, including rings, cages and open structures, which the doping atom stabilizes using contrasting bonding mechanisms. The most strik ...

Development of the Electromagnetic Calorimeter for the Precise Measurement of the Cosmic Ray Positron Fraction with PEBS

Lesya Shchutska

Since almost a century ago, it is known that a quarter of the energy density in the Universe is represented by the dark matter which has been seen only through gravitational interaction. Despite of intensive searches for a dark matter constituent in differ ...

Investigation of liquid LBE embrittlement effects on irradiated ferritic/martensitic steels by slow-strain-rate tensile tests

Nadine Baluc, Yong Dai

In the present work, LBE (lead-bismuth eutectic) embrittlement effects on ferritic/martensitic (FM) steels have been studied by conducting slow-strain-rate tensile (SSRT) testing on T91 and F82H steels either in Ar or in liquid LBE after irradiation to dos ...
