Scientific paper

We propose to obtain GHRS 15 km/s resolution G160M integrations of highly ionized gas absorption toward two AGNs in order to continue our HST program to study highly ionized gas in the unexplored outer Galactic halo. F 9 will be observed in the lines of C IV and N V and Mark 509 in the lines of C IV (with the N V measurements coming from Cycle 2 program GO3463). The spectral integrations are planned to also provide important low ionization measurements of absoprtion by Mg II, S II, and Si II. The data will be used to study such questions as: What is the physical properties of gas in the outer Galactic halo? Does the Galaxy have a highly ionized outer boundary? what are the ionization processes occurring in the outer Galactic halo? Does the Galaxy have a high velocity cloud phenomenon detectable in high ionizatioin lines? What are the relationships between the high ionization and low ionization absorption? What is the relationship between absorption occurring in the outer Galactic halo and that seen in quasar absorption line systems at low and high redshifts?
