Constraints on cluster density profiles from strong lensing and velocity dispersion data: importance of ellipticity and substructures
We address the question of how well the density profile of galaxy clusters can be determined by combining strong lensing and velocity dispersion data, as recently done by Sand et al. We use cosmological dark matter simulations of clusters to test the reliability of the method, producing mock catalogues of tangential and radial gravitational arcs and simulating the radial velocity dispersion pro...
متن کاملSubstructures in hydrodynamical cluster simulations
The abundance and structure of dark matter subhalos has been analyzed extensively in recent studies of dark matter-only simulations, but comparatively little is known about the impact of baryonic physics on halo substructures. We here extend the SUBFIND algorithm for substructure identification such that it can be reliably applied to dissipative hydrodynamical simulations that include star form...
متن کاملCluster-Dependent Epenthesis Asymmetries
Anaptyxis-prothesis asymmetries, common in loanword adaptation and interlanguage phonology, are characterized by vowel insertion before sibilant + stop clusters, but into obstruent + sonorant clusters. I propose that such patterns reflect an epenthesis strategy in which the site of epenthesis is chosen to maximize perceptual similarity between input and output. Experimental evidence in support ...
متن کاملCluster Arc Statistics
We study the strong gravitational lensing properties of galaxy clusters obtained from N-body simulations with standard ΛCDM cosmology. We have used the 32 most massive clusters from a simulation at various redshifts and ray-traced through the clusters to investigate the giant arcs statistics. We have found that ∼ 40 − 50% of the clusters that produce giant arcs give multiple arcs, which agrees ...
متن کاملBayesian Network Sensitivity to Arc-Removal
Arc-removal is usually employed as part of an approximate inference scheme for Bayesian networks, whenever exact inference is intractable. We consider the removal of arcs in a different setting, as a means of simplifying a network under construction. We show how sensitivity functions, capturing the effects of parameter variation on an output of interest, can be employed to describe detailed eff...
