Assigned ID: 333 ----- Attempting Submission 1 (Fri Feb 25 10:56:43 GMT 2011) ----- HST Phase I Proposal 333 (ms.cycle19.apt) successfully submitted. NOTES FROM JAN 16 SUBMISSION: Acquisition exposure times (SEARCH/PEAKXD/PEAKD) increased for visits 1/2/6/7/8 and decreased for visit 3 following CS suggestion to check all acquisition calculations. Acquisition ETC numbers updated. NOTES FROM DEC 14 SUBMISSION: Buffer times shortened for 3 targets: Fairall 9 (variable), NGC7714 (extended source), and ESO292-G24 (extended source) as a precautionary measure, since the GALEX fluxes are higher than the FUSE fluxes I had been using previously. ETC IDs updated. This was discussed with CS Cristina Oliveira. NOTES FROM OCT 17 SUBMISSION: In this submission I have updated the buffer times and ETC IDs following discussion with CS Cristina Oliveira. The new ETC calculations use the individual QSO redshifts and the FOS-based QSO template. ----- Attempting Submission 1 (Fri Jul 08 13:45:13 GMT 2011) ----- ----- Attempting Submission 2 (Mon Oct 17 14:34:45 GMT 2011) ----- ----- Attempting Submission 3 (Wed Dec 14 17:19:37 GMT 2011) ----- ----- Attempting Submission 4 (Mon Jan 16 17:08:40 GMT 2012) ----- The "remaining diagnostics" relate to this message: "For the best data quality, it is strongly recommended that all four FP-POS positions be used when observing at a given COS CENWAVE setting." This message appears because for 6 of my 8 targets, I am using 2 FP-POS positions per COS grating, instead of 4. This was decided after discussing the observing strategy with my Contact Scientist Cristina Oliveira. Thanks, Andrew Fox Ionization in the Magellanic Stream: A Case Study of Galactic Accretion Gaseous inflow plays an important role in spiral galaxy evolution, bringing in the fuel that powers new cycles of star formation. But does the gas come in cold, warm, or hot? Are most infalling clouds destroyed by evaporating into the hot corona? To address these poorly-understood processes, we propose a 20-orbit HST/COS study of the Magellanic Stream (MS), the best known example of gaseous accretion, which shows clear signs of a disruptive interaction with the corona. The MS will be detected in a wide range of low-ion and high-ion absorption lines in the COS spectra of 8 background AGN, each sampling a different region of the Stream. Combining with existing observations from FUSE, VLT/UVES, the Green Bank Telescope (H I), and the WHAM telescope (H-alpha), we will fully characterize the MS ionization level, by determining the total column density of low-ion and high-ion gas in each sight line. This will allow us to derive the total (neutral+ionized) MS mass and the accretion rate it represents. We will then determine the fate of each region of the Stream, by deriving the evaporation timescale and comparing it to the infall timescale. The data will also allow for a comprehensive study of chemical enrichment and dust content in the MS, thus constraining its history. The proposed observations will provide quantitative information on the physical and chemical state of infalling gas clouds, and will test simulations that predict such clouds are evaporated by their interaction with the hot corona. The high sensitivity of COS and the wide range of lines available in the UV make these HST observations the key to completing our multi-wavelength program.
This program involves COS observations of 8 targets with the G130M/1291 and G160M/1589 settings. Each target can be observed in one visit. 6 targets have 2-orbit visits (1 with G130M and 1 with G160M). The remaining 2 targets (the fainter ones) have 4-orbit visits (2 with G130M and 2 with G160M). Target coordinates are expected to be good to 0.1-0.2 arcseconds, but to be sure an ACQ/SEARCH exposure with SCAN-SIZE=2 is taken before the ACQ/PEAKXD and ACQ/PEAKD exposures. All acquisition exposures use exposure times between 2 and 5 seconds. Target S/N ratios are 25 at 1200 A (G130M), and 20 at 1500 A (G160M) after combining all sub-exposures. Buffer times are set equal to the actual exposure time or to half the actual exposure time for the brighter targets, according to the ETC calculations. For several targets, the FUV fluxes were measured by FUSE at 1030 Angstroms, so the flux at 1300 A has been estimated but is not known exactly. For the 6 brighter targets done in two orbits each, 2 FP-POS positions are used per grating. For the 2 fainter targets done in four orbits each, 4 FP-POS positions are used per grating.
