Extreme Ultraviolet Absorption Lines in LyA Forest Absorbers and the Oxygen Abundance in the Intergalactic Medium
R. C. Telfer, G. A. Kriss, W. Zheng +2
We create stacked composite absorption spectra from Hubble Space Telescope Faint Object Spectrograph data from four quasi-stellar objects to search for absorption lines in the extr…
The UCSD HIRES/KECK I Damped Lya Abundance Database: IV. Probing Galactic Enrichment Histories with Nitrogen
Jason X. Prochaska, Richard B. C. Henry, John M. O'Meara +5
We present 14 N^0 measurements from our HIRES/Keck database of damped Lya abundances. These data are combined with measurements from the recent and past literature to build an homo…
Non-Gaussian Features of Transmitted Flux of QSO's Ly Absorption: Intermittent Exponent
Jesus Pando, Long-Long Feng, Priya Jamkhedkar +4
We calculate the structure function and intermittent exponent of the 1.) Keck data, which consists of 29 high resolution, high signal to noise ratio (S/N) QSO Ly absorption spec…
The UCSD HIRES/KeckI Damped Lya Abundance Database III. An Empirical Study of Photoionization in the Damped Lya System Toward GB1759+7539
Jason X. Prochaska, J. Christopher Howk, John M. O'Meara +5
We investigate the ionization state of the damped Lya system at z=2.62 toward GB1759+7539 through an analysis of ionic ratios sensitive to photoionization: ArI/SII, FeIII/FeII, NII…
