On the Clustering of Lyman Alpha Clouds

We examine the correlational property of Lyα clouds (along the line of sight) in detail utilizing a hydrodynamic simulation of Lyα clouds in a cold dark matter universe with a cosmological constant, and compare it to that of mass and galaxies. We show that the correlation strength of Lyα clouds is somewhat weaker than that of the underlying matter, which in turn should be weaker than that of ga...

Two - Point Angular Correlation Function )

The Two Point Angular Correlation Function (TPACF) is a mathematical equation that has applications in many areas. In our project, the Two Point Angular Correlation Function is used as a way to measure the probability of finding an astronomical body at a given angular distance from another astronomical body. We were given working sequential code as a starting point. The sequential code took in ...

The Two - Point Correlation Function at Redshift

We present the results of a study of the two-point correlation function for a sample of field galaxies taken from the CNOC cluster survey. The sample consists of 144 galaxies within a contiguous region of space subtending 225 square arcminutes. The objects have r-band magnitudes 17.0 ≤ r ≤ 21.7 and redshifts 0.21 ≤ z ≤ 0.53. The median redshift of the sample is z̄ = 0.36. The real space correlat...

Properties of High-redshift Lyman Alpha Clouds Ii. Statistical Properties of the Clouds

Curve of growth analysis, applied to the Lyman series absorption ratios deduced in our previous paper, yields a measurement of the logarithmic slope of distribution of Lyman α clouds in column density N . The observed exponential distribution of the clouds’ equivalent widths W is then shown to require a broad distribution of velocity parameters b, extending up to 80 km s. We show how the expone...

Image correlation spectroscopy of randomly distributed disks.

Image correlation spectroscopy (ICS) has been widely used to quantify spatiotemporal distributions of fluorescently labelled cell membrane proteins and receptors. When the membrane proteins are randomly distributed, ICS may be used to estimate protein densities, provided the proteins behave as point-like objects. At high protein area fraction, however, even randomly placed proteins cannot obey ...
