A uniform analysis of the Lyman alpha forest at z = 0-5: III. HST FOS Spectral Atlas
Jill Bechtold, Adam Dobrzycki, Brenda Wilden +5
We analyzed the absorption line spectra of all quasars observed with the high resolution gratings of the Faint Object Spectrograph on board the Hubble Space Telescope. We examined…
A uniform analysis of the Lyman alpha forest at z = 0-5: IV. The clustering and evolution of clouds at z < 1.7
Adam Dobrzycki, Jill Bechtold, Jennifer Scott +1
We present results on the evolution and clustering of Ly-alpha lines at low z. The sample contains 1298 Ly-alpha lines from 165 quasar spectra mined from the archives of the HST/FO…
The Extragalactic Ionizing Background at Low Redshift
J. Scott, J. Bechtold, M. Morita +2
We present a measurement of the mean intensity of the hydrogen-ionizing background radiation field at low redshift using 906 Ly-alpha absorption lines in 151 quasar spectra from th…
Mapping the Galactic Halo I. The `Spaghetti' Survey
Heather L. Morrison, Mario Mateo, Edward W. Olszewski +5
We describe a major survey of the Milky Way halo designed to test for kinematic substructure caused by destruction of accreted satellites. We use the Washington photometric system…
