0 Assigned ID: 7728 ----- Attempting Submission 1 (Thu Apr 16 22:27:57 GMT 2026) ----- HST Phase I Proposal 7728 successfully submitted. Receipt: # 7728-1 Submission #1 for this program... 1) All are single orbit visits. Ove visit/orbit per target. 2) Initial ACQ for each target has been added. F28X50LP is used when possible, F28X50OII is used when the target is too bright (within 70% of full-well electron depth with 0.1 seconds) for the long pass filter. Exposures were designed to reach ~ 38,911 - 72,226 electrons (SNR ~ 275 - 429). 3) We are still finalizing the ACQ/PEAK strategy and exposures will be added in a revision. 4) Each target has a single 1800s long spectroscopic exposure with E140H/c1343/0.2X0.09. The science exposures will be adjusted in case of overruns after the ACQ/PEAK exposures are added. 5) Set WAVECAL=NO and added GO-WAVECALS in all visits to move the wavecal exposure to the end of the orbit (to make space for the ACQ/PEAK exposure to be added). -1460947652 ----- Attempting Submission 1 (Tue Aug 18 22:17:49 GMT 2026) ----- Tracing Gas Flows Locally to Understand Gas Flows Globally The Milky Way provides a unique opportunity to study how gas, metals, and dust flow into and out of galaxies. Astronomers do not yet know where or how local gas flows connect up and become collimated into large scale outflows. By targeting the disk-halo interface up to z ~ 1 kpc, this proposal probes a key region where this transition happens and local flows becomes global. We propose HST/STIS E140H echelle observations of 20 Milky Way inner-Galaxy OB stars located within the disk-halo interface spanning a range of Galactic latitudes b = +/-20 degrees, and inside the Galactic tangent points (l <~ +/-30 degrees). These observations will be combined with HST/STIS E140H archival spectra of 2 inner-Galaxy sight lines that meet the same regional criteria. The sample stars are chosen because they form pairs of sight lines which match very closely in longitude (< 0.68 degrees) and are at comparable distances, but fall at different latitudes. Thus, the pairs create a vertical slice in latitude extending from the disk through the disk-halo interface at a single longitude through 10 places in the inner-Galaxy, divided evenly between the inner-Galactic quadrants I and IV. High-resolution stellar absorption-line spectroscopy of these close pairs is required in order to precisely trace kinematic signatures of Local outflows from the disk, through the disk-halo interface, and into the lower circumgalactic medium. We will observe 20 Galactic OB stars with STIS/E140H. This description will be updated with appropriate details in the next iteration.
