Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short Wavelength Observation of Solar Analogs
Dan Lubin, Carl Melis, David Tytler
We have identified a sample of 33 Sun-like stars observed by the {\it International Ultraviolet Explorer (IUE)} with the short wavelength (SW) spectrographs that have ground-based…
Spectroscopic Analysis of H I Absorption Line Systems in 40 HIRES Quasars
T. Misawa, D. Tytler, M. Iye +4
We list and analyze H I absorption lines at redshifts 2 < z < 4 with column density (12 < log(N_HI) < 19) in 40 high-resolutional (FWHM = 8.0 km/s) quasar spectra obtained with the…
A Census of Intrinsic Narrow Absorption Lines in the Spectra of Quasars at z=2-4
T. Misawa, J. C. Charlton, M. Eracleous +5
We use Keck/HIRES spectra of 37 optically bright quasars at z=2-4 to study narrow absorption lines that are intrinsic to the quasars (intrinsic NALs, produced in gas that is physic…
Continuous statistics of the Lyman-alpha forest at 0 < z < 1.6: the mean flux, flux distribution, and autocorrelation from HST FOS spectra
David Kirkman, David Tytler, Dan Lubin +1
We measure the amount of absorption in the Lyman-alpha forest at 0 < z < 1.6 in HST FOS spectra of 74 QSOs. At 0 < z < 1.6 we find that 79% of the absorption is from the low densit…
Probing Quasar Outflows with Intrinsic Narrow Absorption Lines
T. Misawa, M. Eracleous, J. C. Charlton +5
We present statistical and monitoring results of narrow absorption lines that are physically related to quasars (i.e., intrinsic NALs). We use Keck/HIRES spectra of 37 optically br…
The H I opacity of the intergalactic medium at redshifts 1.6 < z < 3.2
David Kirkman, David Tytler, Nao Suzuki +8
We use high quality echelle spectra of 24 QSOs to provide a calibrated measurement of the total amount of Lyman-alpha forest absorption (DA) over the redshift range 2.2 < z < 3.2.…
