Sources of contamination to weak lensing tomography: redshift-dependent shear measurement bias

, 2008
The current methods available to estimate gravitational shear from astronomical images of galaxies introduce systematic errors which can affect the accuracy of weak lensing cosmological constraints.

Extremely Small Sizes for Faint z~2-8 Galaxies in the Hubble Frontier Fields: A Key Input For Establishing their Volume Density and UV Emissivity [PDF]

, 2017
We provide the first observational constraints on the sizes of the faintest galaxies lensed by the Hubble Frontier Fields (HFF) clusters. Ionizing radiation from faint galaxies likely drives cosmic reionization, and the HFF initiative provides a key ...

Calibration of the Mass-Temperature Relation for Clusters of Galaxies Using Weak Gravitational Lensing

, 2007
The main uncertainty in current determinations of the power spectrum normalization, sigma_8, from abundances of X-ray luminous galaxy clusters arises from the calibration of the mass-temperature relation. We use our weak lensing mass determinations of 30

Thermal analysis of isotropic plates using hyperbolic shear deformation theory

Applied and Computational Mechanics, 2013
In this paper, thermal analysis of a thick isotropic rectangular plate is carried out using the hyperbolic shear deformation theory (HYSDT). The displacement field of the theory contains three variables.

Effective Width of Floor Systems for Application in Seismic Analysis [PDF]

, 1980
Effective width coefficients for floor systems have been developed for use in the analysis of frames subjected to lateral seismic loads. The results cover a wide range of the governing nondimensional parameters, and are applicable to floor slabs with ...

Next-to-Leading Order Shear Viscosity in lambda phi^4 Theory

, 2007
We show that the shear viscosity of lambda phi^4 theory is sensitive at next-to-leading order to soft physics, which gives rise to subleading corrections suppressed by only a half power of the coupling, eta = [3033.54 + 1548.3 m_{th}/T] N T^3]/[ (N+2)/3 ...

Shear Analogy Stiffness Adjustment for CLT Plates

BioResources
In serviceability limit state, one-dimensional approaches are commonly used to estimate the bending stiffness and vertical displacement of cross-laminated timber (CLT) panels, such as the shear analogy method combined with mechanics of materials ...

Weak lensing calibration of mass bias in the REFLEX+BCS X-ray galaxy cluster catalogue

, 2017
The use of large, X-ray selected galaxy cluster catalogues for cosmological analyses requires a thorough understanding of the X-ray mass estimates. Weak gravitational lensing is an ideal method to shed light on such issues, due to its insensitivity to ...
