Strong and weak lensing of Gravitational Waves: a semi-analytical approach
Giulia Cusin, Ruth Durrer, Irina Dvorkin
In this paper we study gravitational lensing of gravitational wave events. The main point of the present work is to introduce a semi-analytic approach so that each ingredient can b…
Properties of the stochastic astrophysical gravitational wave background: astrophysical sources dependencies
Giulia Cusin, Irina Dvorkin, Cyril Pitrou +1
This article explores the properties (amplitude and shape) of the angular power spectrum of the anisotropies of the astrophysical gravitational wave background (AGWB) focusing on t…
Stochastic gravitational wave background anisotropies in the mHz band: astrophysical dependencies
Giulia Cusin, Irina Dvorkin, Cyril Pitrou +1
We show that the anisotropies of the astrophysical stochastic gravitational wave background in the mHz band have a strong dependence on the modelling of galactic and sub-galactic p…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Comment on the article "Anisotropies in the astrophysical gravitational-wave background: The impact of black hole distributions" by A.C. Jenkins et al. [arXiv:1810.13435]
Giulia Cusin, Irina Dvorkin, Cyril Pitrou +1
We investigate the discrepancy pointed out by Jenkins et al. in Ref. [1] between the predictions of anisotropies of the astrophysical gravitational wave (GW) background, derived us…
First predictions of the angular power spectrum of the astrophysical gravitational wave background
Giulia Cusin, Irina Dvorkin, Cyril Pitrou +1
We present the first predictions for the angular power spectrum of the astrophysical gravitational wave background constituted of the radiation emitted by all resolved and unresolv…
The origin of dispersion in DLA metallicities
Irina Dvorkin, Joseph Silk, Elisabeth Vangioni +2
Recent chemical abundance measurements of damped Ly-alpha absorbers (DLAs) revealed an intrinsic scatter in their metallicity of ~0.5 dex out to z~5. In order to explore the origin…
Galaxy formation
Joseph Silk, Arianna Di Cintio, Irina Dvorkin
Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters,…
SZ power spectrum and cluster numbers from an extended merger-tree model
Irina Dvorkin, Yoel Rephaeli, Meir Shimon
We have recently developed an extended merger-tree model that efficiently follows hierarchical evolution of galaxy clusters and provides a quantitative description of both their da…
Constraints on the Neutrino Mass from SZ Surveys
M. Shimon, Y. Rephaeli, N. Itzhaki +2
Statistical measures of galaxy clusters are sensitive to neutrino masses in the sub-eV range. We explore the possibility of using cluster number counts from the ongoing PLANCK/SZ a…
An expanded merger-tree description of cluster evolution
Irina Dvorkin, Yoel Rephaeli
We model the formation and evolution of galaxy clusters in the framework of an extended dark matter halo merger-tree algorithm that includes baryons and incorporates basic physical…
