The Missing Baryons Around Nearby Dwarf Galaxies

I made a small mistake on the ETC referenced and have corrected that. I've made all the suggested changes and am grateful for the input. 1549377475 ----- Attempting Submission 5 (Wed Oct 30 19:24:58 GMT 2013) ----- ----- Attempting Submission 6 (Thu Oct 31 18:42:50 GMT 2013) ----- ----- Attempting Submission 7 (Mon Nov 18 17:05:01 GMT 2013) ----- HST Phase II Proposal 13347 (13347_18Nov13.apt) successfully submitted. ----- Attempting Submission 8 (Mon Nov 18 22:22:09 GMT 2013) ----- I ran all tools and I think that these should be ok. The Missing Baryons Around Nearby Dwarf Galaxies Dwarf galaxies are missing nearly all of their baryons, which have presumably flowed away as a wind. This mass loss accounts for a significant fraction of all baryons lost from galaxies, so there is great interest in determining the size and scope of the gas lost. This gas is not visible in emission but is detectable through absorption features toward background AGNs. Here we propose to observe the absorbing material around three isolated dwarfs on the periphery of the Local Group: Sextans A, Sextans B, and NGC 3109. Unlike more distant dwarfs, the star formation history and cold gaseous content of these galaxies are well-studied. The isolation of these dwarfs, far from large galaxies, means that they have not yet interacted with other systems so their mass loss history is well-preserved, making them ideal targets for study. There are FUV magnitudes from GALEX for all targets and we use those, along with the COS spectroscopic ETC, to determine the exposure time to achieve a S/N of about 10 per resolution element for the G130M and G160M settings. We will adopt what has become the standard setting, having multiple spectra with central wavelengths of 1291, 1300, 1309, and 1318 for the G130M and 1589, 1600, 1611, and 1623 for the G160M. The total amount of time for an object is divided between G130M and G160M in the approximate ratio of 1:2. Each object has an acquistion image and then a set of 4 G130M spectra and 4 G160M spectra, each with different wavelength setting, making a total of 8 spectra per object. Two targets, Mrk 1253 and PG 1001+054 (2XMM J100420.0+051300) are observed for 3 orbits each and the other three are each observed for 5 orbits.
