The Role of Spatial Coherence and Orbital Angular Momentum of Light in Astronomy [PDF]

, 2014
The orbital angular momentum (OAM) of light is potentially interesting for astronomical study of rotating objects such as black holes, but the effect of reduced spatial coherence of astronomical light sources such as stars is largely unknown.

New Parametrizations of Non-Gaussian Line-of-sight Velocity Distribution [PDF]

, 1995
A five-parameter fitting formula for the line-of-sight stellar velocity distributions of steady state systems is proposed. It can faithfully reproduce velocity distributions of theoretical models ranging from nearly Gaussian profiles to strongly skewed ...

Reliability Analysis of Centralized Radio Access Networks in Non-Line-of-Sight and Line-of-Sight Scenarios

IEEE Access, 2019
The fifth generation (5G) wireless network technology is set to be standardized by 2020, where the main goals are to improve capacity, reliability, and energy efficiency while reducing latency and massively increasing connection density.

Continuum Line-of-Sight Percolation on Poisson-Voronoi Tessellations

, 2020
In this work, we study a new model for continuum line-of-sight percolation in a random environment driven by the Poisson-Voronoi tessellation in the $d$-dimensional Euclidean space.

Projection, Spatial Correlations, and Anisotropies in a Large and Complete Sample of Abell Clusters [PDF]

, 1999
An analysis of R >= 1 Abell clusters is presented for samples containing recent redshifts from the MX Northern Abell Cluster Survey. The newly obtained redshifts from the MX Survey as well as those from the ESO Nearby Abell Cluster Survey (ENACS) provide

Intervening BLR Clouds' Effects on Optical/UV Spectrum [PDF]

, 2012
Recent x-ray observations of Mrk 766 suggest that broad emission line region clouds cross our line of sight and produce variable x-ray absorption. Here we investigate what optical/ultraviolet spectroscopic features would be produced by such "Intervening ...
