Rotation Curve Measurement Using Cross-correlation
Longslit spectroscopy is entering an era of increased spatial and spectral resolution and increased sample size. Improved instruments reveal complex velocity structure that cannot be described with a one-dimensional rotation curve, yet samples are too numerous to examine each galaxy in detail. Therefore, one goal of rotation curve measurement techniques is to flag cases in which the kinematic s...

متن کاملDispersion curve measurement using Talbot bands
2014 Talbot bands, looking like a channelled spectrum, are produced when a phase plate is partly inserted in the field of a spectroscope. The position and the spacing of the bands in the spectrum of the source directly depends on the optical thickness and therefore the refractive index of the phase plate. In the case of a transmission grating spectroscope, the bands appear only in spectral orde...
متن کاملComputed Tomographic measurement of distal femor rotation in Iranian population
Background: Proper rotation of components in total knee arthroplasty (TKA) will largely affect the postoperative outcome. Ethnical variation may affect rotational profile. We aimed to evaluate distal femur rotation in Iranian population using transepicondylar axes. Methods : From a total of 450 knee CT scans and via consecutive sampling, 150 qualified subjects with normal lower extremities ...
متن کاملThe Universal Rotation Curve of Spiral Galaxies
The observed strong dark-to-luminous matter coupling is described by a bias relation between visible and dark matter sources. We discuss the bias which emerges in the case where the topological structure of the Universe at very large distances does not match properly that of the Friedman space. With the use of such ”topological” bias, we construct the Universal Rotation Curve (URC) for spirals ...
