Diffuse gamma-ray constraints on dark matter revisited I: the impact of subhalos
We make a detailed analysis of the indirect diffuse gamma-ray signals from dark matter annihilation in the Galaxy. We include the prompt emission, as well as the emission from inverse Compton scattering whenever the annihilation products contain light lept ...
Iop Publishing Ltd2012TRACE and TRAC-BF1 Benchmark Against Leibstadt Data During the Event Inadvertent Opening of Relief Valves
In framework of introducing TRACE code to transient analyses system codes for Leibstadt Power Plant (KKL), a conversion process of existing TRAC-BF1 model to TRACE has been started within KKL. In the first step, TRACE thermal-hydraulic model for KKL has be ...
American Nuclear Society2012The cosmological impact of intrinsic alignment model choice for cosmic shear
We consider the effect of galaxy intrinsic alignments (IAs) on dark energy constraints from weak gravitational lensing. We summarize the latest version of the linear alignment model of IAs, following a brief note of Hirata & Seljak and further interpretati ...
Blackwell Publishing Ltd, Oxford2012Next decade of sterile neutrino studies
Alexey Boyarsky, Oleg Ruchayskiy
We review the status of sterile neutrino dark matter and discuss astrophysical and cosmological bounds on its properties as well as future prospects for its experimental searches. We argue that if sterile neutrinos are the dominant fraction of dark matter, ...
2012Perturbation Theory Of The Cosmological Log-Density Field
The matter density field exhibits a nearly lognormal probability density distribution after entering into the nonlinear regime. Recently, it has been shown that the shape of the power spectrum of a logarithmically transformed density field is very close to ...
2011Physical and numerical modeling of the spillways and plunge pools of Koman Dam in Albania
Anton Schleiss, Giovanni De Cesare, Gaël Epely Chauvin, Matteo Paolo Elia Antonio Federspiel, Milad Daneshvari, Mathias Malquarti
The 115 m high Koman Dam is located in the northern part of Albania and is part of the Drin River hydroelectric cascade. The dam is equipped with two tunnel spillways with flip buckets at their downstream limits. Two large scour holes were created in the d ...
2011A Framework for Numerical Simulations of Structure Formation
In the absence of a full analytical treatment of nonlinear structure formation in the universe, numerical simulations provide the critical link between the properties of the underlying model and the features of the observed structures. Currently N-body sim ...
EPFL2011Non-linear matter power spectrum from Time Renormalisation Group: efficient computation and comparison with one-loop
Julien Lesgourgues, Benjamin Audren
We address the issue of computing the non-linear matter power spectrum on mildly non-linear scales with efficient semi-analytic methods. We implemented M. Pietroni's Time Renormalization Group (TRG) method and its Dynamical 1-Loop (D1L) limit in a numerica ...
2011Results of the GREAT08 Challenge: an image analysis competition for cosmological lensing
Frédéric Courbin, Matthias Bethge, Anaïs Marie Rassat, Marc Gentile, Richard Massey, Michael Hirsch
We present the results of the Gravitational LEnsing Accuracy Testing 2008 (GREAT08) Challenge, a blind analysis challenge to infer weak gravitational lensing shear distortions from images. The primary goal was to stimulate new ideas by presenting the probl ...
Blackwell Publishing Ltd, Oxford2010Compressed sensing reconstruction of a string signal from interferometric observations of the cosmic microwave background
Pierre Vandergheynst, Yves Wiaux, Gilles Puy
We propose an algorithm for the reconstruction of the signal induced by cosmic strings in the cosmic microwave background (CMB), from radio-interferometric data at arcminute resolution. Radio interferometry provides incomplete and noisy Fourier measurement ...
