Towards a Precise Measurement of Matter Clustering: Lyman-alpha Forest Data at Redshifts 2-4
Rupert A. C. Croft, David H. Weinberg, Mike Bolte +5
We measure the filling factor, correlation function, and power spectrum of transmitted flux in a large sample of Lya forest spectra, comprised of 30 Keck HIRES spectra and 23 Keck…
The Deuterium to Hydrogen Abundance Ratio Towards a Fourth QSO: HS0105+1619
John M. O'Meara, David Tytler, David Kirkman +4
We report the measurement of the primordial D/H abundance ratio towards QSO \object. The column density of the hydrogen in the Lyman limit system is high, \lnhi $=…
Damped Lyman alpha systems at z=0.68 and z=1.15 towards HE 1122-1649 and HE 0515-4414
A. de la Varga, D. Reimers, D. Tytler +2
Detailed analysis of the spectral lines from two low redshift damped Lyman alpha absorbers (DLA) confirms that they are a heterogeneous population. Both systems have low metal abun…
On Estimating the QSO Transmission Power Spectrum
Lam Hui, Scott Burles, Uros Seljak +3
We present new methods to minimize the systematic and random errors for measuring the transmission power spectrum from the Lyman-alpha forest. Sources of systematic errors explored…
QSOs and Absorption Line Systems Surrounding the Hubble Deep Field
Daniel E. Vanden Berk, Chris Stoughton, Arlin P. S. Crotts +2
We have imaged a 45x45 sq. arcmin. area centered on the Hubble Deep Field (HDF) in UBVRI passbands, down to respective limiting magnitudes of approximately 21.5, 22.5, 22.2, 22.2,…
Review of Big Bang Nucleosynthesis and Primordial Abundances
David Tytler, John M. O'Meara, Nao Suzuki +1
Big Bang Nucleosynthesis (BBN) is the synthesis of the light nuclei, Deuterium, He3, He4 and Li7, during the first few minutes of the universe. This review concentrates on recent i…
