The Metallicity and Dust Content of HVC 287.5+22.5+240: Evidence for a Magellanic Clouds Origin
Limin Lu, Blair D. Savage, Kenneth R. Sembach +3
We estimate the abundances of S and Fe in the high velocity cloud HVC 287.5+22.5+240, which has a velocity of +240 km/s with respect to the local standard of rest and is in the Gal…
Extraplanar Dust in the Edge-On Spiral NGC 891
J. Christopher Howk, Blair D. Savage
We present high-resolution (<0.65") optical broad-band images of the edge-on Sb galaxy NGC 891 obtained with the WIYN 3.5-m telescope. These BVR images reveal a complex network of…
High Signal-to-Noise GHRS Observations of H 1821+643: O VI Associated with a Group of Galaxies at z = 0.226 and Complex Lyman Absorption Profiles at Low Redshift
T. M. Tripp, L. Lu, B. D. Savage
As part of a program to study the relationship between QSO Lyman alpha clouds and galaxies at low redshifts, we have obtained a high signal-to-noise far UV spectrum of H 1821+643 […
Echelle Spectroscopy of QSO Absorption Line Systems with Metals in the Direction of HS 1700+6416
Todd M. Tripp, Limin Lu, Blair D. Savage
We present a high signal-to-noise high resolution spectrum of the radio-quiet QSO HS1700+6416 (z = 2.72). Analysis of the absorption line systems with metals yields the following r…
