Constraints on the Inner Cluster Mass Profile and the Power Spectrum Normalization from Strong Lensing Statistics
Strong gravitational lensing is a useful probe of both the intrinsic properties of the lenses and the cosmological parameters of the universe. The large number of model parameters and small sample of observed lens systems, however, have made it difficult to obtain useful constraints on more than a few parameters from lensing statistics. Here we examine how the recent Wilkinson Microwave Anisotr...

متن کاملStrong and Weak Lensing Constraints on Galaxy Mass Distribution
Gravitational Lensing is a unique tool to constrain the mass distribution of collapsed structures, this is particularly true for galaxies, either on a case by case basis using multiple images of background sources (such as quasars), or statistically using the so called galaxy-galaxy lensing technique. First, I will present the lensing theory, and then discuss the various methods applied to curr...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولCluster Strong Lensing Constraints on Dark Energy
Cluster strong lensing can be used to obtain constraints on cosmological parameters, in particular as we show here, the dark energy equation of state. This is achieved by using multiple images of sources at two or more distinct redshift planes. Utilizing many families of multiply imaged sources we obtain purely geometric constraints on dark energy that are largely independent of the properties ...
