The Origin of \lya Absorption Systems at ---Implications from the Hubble Deep Field

Hsiao-Wen Chen, Kenneth M. Lanzetta, Alberto Fernández-Soto

The Hubble Deep Field images have provided us with a unique chance to relate statistical properties of high-redshift galaxies to statistical properties of \lya absorption systems.…

A Younger Age for the Universe

Charles H. Lineweaver

The age of the universe in the Big Bang model can be calculated from three parameters: Hubble's constant, h; the mass density of the universe, Omega_m; and the cosmological constan…

A method for detecting gravitational waves coincident with gamma ray bursts

M. T. Murphy, J. K. Webb, I. S. Heng

The mechanism for gamma ray bursters and the detection of gravitational waves (GWs) are two outstanding problems facing modern physics. Many models of gamma ray bursters predict co…

Galaxies of Redshift z > 5: The View from Stony Brook

Kenneth M. Lanzetta, Hsiao-Wen Chen, Alberto Fernandez-Soto +3

We report on some aspects of our efforts to establish properties of the extremely faint galaxy population by applying our photometric redshift technique to the HDF and HDF-S WFPC2…

Large-scale structure in the Lyman-alpha forest II: analysis of a group of ten QSOs

J. Liske, J. K. Webb, G. M. Williger +2

The spatial distribution of Ly-alpha forest absorption systems towards ten QSOs has been analysed to search for large-scale structure over the redshift range 2.2 < z < 3.4. The QSO…

CMBology

Charles H. Lineweaver

The details of the CMB power spectrum are being revealed through the combined efforts of the world's CMBologists. The current data set constrains several cosmological parameters. A…
