• W2029986177 abstract "This paper presents the results of an analysis of the Milky Way absorption lines found in the Hubble Space Telescope (HST) Quasar Absorption Line Key Project database for 83 QSOs observed with the Faint Object Spectrograph G190H and G270H gratings, of which 16 QSOs are also observed with the G130H grating. The HST Key Project observations are supplemented with high-quality 21 cm H I emission-line observations mostly obtained with the NRAO 43 m radio telescope. The Milky Way halo gas exhibits mixed ionization absorption with high-ionization absorption from Si IV and C IV substantially weaker than the extremely strong intermediate- and low-ionization absorption from Si III, Si II, C II, Mg II, and Fe II. For a sample of 16 QSOs observed in the far-UV, the median velocity equivalent widths of very strong lines of Si IV, Si III, and Si II are 60, 180, and 180 km s-1, respectively. Velocity equivalent widths this large for Si III and Si II imply the existence of high velocity dispersion moderate- (Si III) and low-ionization (Si II) gas along many paths through the Galactic halo. Measures of the Galactic damped Lyα line toward 14 QSOs permit the determination of N(H I)Lyα through the gaseous disk and halo of the Galaxy. The values of N(H I)Lyα range from 0.64 × 1020 to 3.37 × 1020 cm-2 with N(H I)Lyα| sin b| averaging (1.29 ± 0.49) × 1020 cm-2. A comparison of N(H I)Lyα with N(H I)21 cm reveals that N(H I)Lyα/N(H I)21 cm for the 10 sight lines where the value of N(H I)Lyα is not significantly affected by geocoronal emission ranges from 0.62 and 0.91. This difference is probably produced by a combination of systematic and random errors and contribution from the small angular scale structure in the H I distribution. Such structure can produce different column densities when sampling gas with an infinitesimal beam in the UV (the angular size of the QSO) compared to the much larger 21' beam of the NRAO 43 m radio telescope." @default.
