Systematic uncertainties in gravitational lensing models: a semi-analytical study of PG1115+080
While the Hubble constant can be derived from observable time delays between images of lensed quasars, the result is often highly sensitive to assumptions and systematic uncertainties in the lensing model. Unlike most previous authors we put minimal restrictions on the radial profile of the lens and allow for non-elliptical lens potentials. We explore these effects using a broad class of models...
متن کاملa study of baudrillards ideas in brian moores fiction
پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...
15 صفحه اولa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Gravitational Lensing by a Compound Population of Halos: Standard Models
Based on observed rotation curves of galaxies and theoretical simulations of dark matter halos, there are reasons for believing that at least three different types of dark matter halos exist in the Universe classified by their masses M and the inner slope of mass density −α : Population A (galaxies): 1010h−1M⊙ . M . 2× 1013h−1M⊙, α ≈ 2; Population B (cluster halos): M & 2× 10 13h−1M⊙, α ≈ 1.3; ...
متن کاملA Catalog of Mass Models for Gravitational Lensing
Many different families of mass models are used in modern applications of strong gravitational lensing. I review a wide range of popular models, with two points of emphasis: (1) a discussion of strategies for building models suited to a particular lensing problem; and (2) a summary of technical results for a canonical set of models. All of the models reviewed here are included in publicly-avail...
