Statistical Properties of the Lyman-alpha ForestBechtold, J., Shectman, S. A. 08 1900 (has links)
We have observed two high -redshift quasars with the echelle spectrograph
and 2D- Frutti Photon Counter at Las Campanas, in order to investigate the
statistical properties of the Lyman -a forest. The two-point correlation function for
the Lyman -a forest lines at z .^s 3 is consistent with zero, for all velocity splittings
A > 50 km /sec. When Lyman -a lines and other metal lines from known metalline
systems are included, the correlation function shows a weak non -zero signal at
small A . We suggest that the weak clustering of the Lyman -a forest detected by
other workers may be the result of contamination by a small number of metal -line
systems and their associated Lyman -a lines.

Redshift Quantization in the Lyman-alpha Forest and the Measurement of qoCocke, W. J., Tifft, W. G. 12 1900 (has links)
We present evidence for redshift quantization in the Lyman -a forest of several QSOs.
The Ly -a data are at redshifts z from 1.89 to 3.74, and the theory of redshift quantization
proposed by Cocke (1983, 1085) is used to scale the quantization interval (24.15 km s -')
to these high redshift. The sealing depends on the deceleration parameter qo, and the
quantization is present at a statistical significance of greater than 99% for qo = 1/2. This
may be taken as confirming the inflationary model of the early history of the universe. The
significance of the quantization is highest at go rs 0.48, and the width of the peak is about
0.03 . The result can also be seen as providing confirmatory evidence for both the theory
of the redshift quantization and the above value of qo, but at a significance of only 03 %.
The scenario proposed for the relativistic generalization of the theory is that of fermion
wavefunctione and quantum operators in a background Riemannian spacetime satisfying
Einstein's field equations.
