Usability of the NFW Galaxy Profile as a Cosmological Tool Estimated from 2-Image Gravitational Lens Systems
The profile of Navarro, Frenk, and White (the NFW profile), which was derived from the N-body simulations of cold dark-matter halos, is a strong candidate for a galaxy or cluster profile. In order to check the usability of the NFW profile as a first approximation of a galaxy model, we studied the characteristic overdensity and scale radius of galaxies by reproducing the image positions and flux...
متن کاملLens Model Degeneracy and Cosmological Tests by Strong Gravitational Lensing
We study the relation between the gravitational lensing observables and the lens model and the cosmological parameters. We estimate the sensitivity of the lensing observables to the lens model and to the cosmological parameters. We show that the observables are primarily dependent on the lens model, while the dependence on cosmological parameters is minor (especially so for the dark energy para...
متن کاملCLASS B0445+123: a new two-image gravitational lens system
A new two image gravitational lens system has been discovered as a result of the Cosmic Lens All-Sky Survey (CLASS). Radio observations with the VLA, MERLIN and the VLBA at increasingly higher resolutions all show two components with a flux density ratio of ∼7:1 and a separation of 1. 34. Both components are compact and have the same spectral index. Follow-up observations made with the VLA at 8...
متن کاملCorrection of Lens-Distortion for Real-Time Image Processing Systems
This paper presents the design of a real-time imaging system, with incorporated the correction of lens-distorted images. It may be used in medical applications (e.g. real-time X-ray image intensifiers), industrial robot vision products or consumer electronics. The system contains two different VLSI-circuits: a transformer and an interpolator. The transformer calculates an address that points to...
متن کاملFluorescence intensity profile of human lens sections.
The fluorescence intensity profiles of thin cross-sections of human lenses were determined as a function of age by scanning microspectrofluorimetry with blue light excitation close to that available in conventional slit-lamp examination (filter transmission maximum 410 nm). The fluorescence intensity of the entire nuclear region increased with age. The profile of the adult lens was manifested a...
