Asymptotically safe gravity as a scalar-tensor theory and its cosmological implications
Asymptotically gravity scalar-tensor theory cosmological implications
2011/10/14
We study asymptotically safe gravity with Einstein-Hilbert truncation taking into account the renormalization group running of both gravitational and cosmological constants. We show the classical beha...
A sufficient condition for de Sitter vacua in type IIB string theory

2011/10/18
We derive a sufficient condition for realizing meta-stable de Sitter vacua with small positive cosmological constant within type IIB string theory flux compactifications with spontaneously broken supe...
Stability and QuasinormalModes of Black holes in Tensor-Vector-Scalar theory: Scalar Field Perturbations
Stability QuasinormalModes Black holes Tensor-Vector-Scalar theory Scalar Field Perturbations Tensor-Vector-Scalar theory
2010/11/16
The imminent detection of gravitational waves will trigger precision tests of gravity through
observations of quasinormal ringing of black holes. While General Relativity predicts just two po-larizat...
A study of relative velocity statistics in Lagrangian perturbation theory with PINOCCHIO
cosmology large-scale structure, methods analytical numerical
2010/11/11
Subject of this paper is a careful and detailed analysis of the PINOCCHIO algorithmfor studying
the relative velocity statistics of merging haloes in Lagrangian perturbation theory. Given
a cosmolog...
Toward an Empirical Theory of Pulsar Emission. IX. On the Peculiar Properties and Geometric Regularity of Lyne & Manchester's
miscellaneous methods MHD plasmas data analysis pulsars general
2010/11/10
Lyne & Manchester (1988) identified a group of some 50 pulsars they called “partial cones”
which they found difficult to classify and interpret. They were notable for their asymmetric
average profil...
