Semi-analytical model of cosmic ray electron transport
Semi-analytical model cosmic ray electron transport
2011/9/28
We present a numerical extension to the analytical propagation model introduced in Hein and Spanier (2008) to describe the leptonic population in the galactic disc. The model is used to derive a possi...
Coherent Cherenkov Radiation from Cosmic-Ray-Induced Air Showers
Coherent Cherenkov Radiation Cosmic-Ray-Induced
2011/9/27
Very energetic cosmic rays entering the atmosphere of the Earth will create a plasma cloud moving with almost the speed of light. The magnetic field of the Earth induces an electric current in this cl...
CMS: Cosmic muons in simulation and measured data
CMS Cosmic muons simulation measured data
2011/10/18
A dedicated cosmic muon Monte-Carlo event generator CMSCGEN has been developed for the CMS experiment. The simulation relies on parameterisations of the muon energy and the incidence angle, based on m...

Coupling of gravity to matter, spectral action and cosmic topology
Coupling of gravity spectral action cosmic topology
2011/7/26
Abstract: We consider a model of modified gravity based on the spectral action functional, for a cosmic topology given by a spherical space form, and the associated slow-roll inflation scenario. We co...

Discovery of GRB clusters allows us to determine coordinates and characteristics of their sources. The objects radiating GRBs are reliably identified with black hole binaries, including the Galactic b...
A Bayesian Approach to Comparing Cosmic Ray Energy Spectra
Bayesian Approach Cosmic Ray Energy Spectra
2011/9/13
A common problem in ultra-high energy cosmic ray physics is the comparison of energy spectra. The question is whether the spectra from two experiments or two
regions of the sky agree within their sta...

2010/12/16
The recently introduced discrete persistent structure extractor (DisPerSE Soubie 2010, paper I) is implemented on realistic 3D cosmological simulations and observed redshift catalogues; it is found th...
Cosmic alignment of the aether
Cosmic alignment aether
2010/12/20
In Einstein-aether theory and Horava gravity, a timelike unit vector is coupled to the spacetime metric. It has previously been shown that in an exponentially expanding homogeneous, isotropic backgrou...
Studies of the performance of the ATLAS detector using cosmic-ray muons
Studies performance ATLAS detector cosmic-ray muons
2011/1/6
Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector.
In Einstein-aether theory and Horava gravity, a timelike unit vector is coupled to the spacetime metric. It has previously been shown that in an exponentially expanding homogeneous, isotropic backgrou...
Observing the Big Bounce with Tensor Modes in the Cosmic Microwave Background: Phenomenology and Fundamental LQC Parameters
Tensor Modes the Cosmic Microwave Background
2010/12/24
Cosmological models where the standard big bang is replaced by a bounce have been studied for decades. The situation has, however, dramatically changed in the past years for two reasons: first, becaus...
A central theme in cosmology is the perplexing fact that the Universe is undergoing an accelerating expansion. The latter, one of the most important and challenging current problems in cosmology, rep...
