INEFFICIENT ORDERING OF FP-POS POSITIONS UPDATE (submission 3 - Feb 2018) We were requested by STScI to use all FP-POS for the G160M observations. If the UDG is at a velocity ~ -1000 km/s of Coma, the S/N of the CIV absorption will be lower than if only FP-POS=3 & 4 has been used, because the other FP-POS wavelengths don't cover that velocity. UPDATE (submission 2) This submission includes the 2 extra orbits awarded by the TTRB to recover SiIV absorption from target 2 using the G160M grating. The 10 orbits are now divided between 6 for the G130M/1291 setting and 4 for the G160M/1577 settings. Notes on "Warnings": G130M: Impossible to implement a full set of FP-POS as there are only 2 for the 1291 setting of the G130M. For the two FP-POS settings, FP-POS=3 is always selected first before FP-POS=4; this follows the "most effecient order" as stated in the IHB of 1, 2, 3 & 4 when 1 & 2 doesn't exist. G160M: Want to use only FP-POS =3 and 4 to get smallest minimum-wavelengths to cover CIV 1548 at Coma velocities. FP-POS 3 & 4 should start at 1577 and 1573.9A, which corresponds to CIV 1548 at cz=5580 and 4980 km/s. [FP-POS=2 would start at 1580.1A == 6180 km/s, which is more than the systemic velocity of Coma.] BUFFER-TIME seems high (24,365 sec), but is 2/3 of that given by the etc COS.sp.1014400 All targets are quoted as having position accuracies of 0.4 arcsec, so only a simple ACQ-IMAGE is required. 2096306012 ----- Attempting Submission 1 (Wed Jul 19 02:24:18 GMT 2017) ----- HST Phase II Proposal 15195 (udgs.apt) successfully submitted.

The Baryon Reservoirs in Ultra Diffuse Galaxies (UDGs) Ultra Diffuse Galaxies (UDGs) are galaxies with large effective radii but very low surface brightness. They were recently discovered in unprecedented numbers in the Coma Cluster, and are now being found in other clusters, as well as in the field. Their origin remains far from clear. In this proposal, we request time to observe three QSOs that lie behind three UDGs, using the COS G130M grating, in order to search for absorption lines from the interstellar and circumgalactic medium of the UDGs. Because the properties of UDGs are likely tied to their locations, the UDGS have been selected to reside in three different environments --- in Coma, in the Fornax Cluster, and in the field. The QSO sightlines probe the inner regions of the galaxies at radii of 1, 7 and 11 kpc, which should be small enough to detect high column densities of neutral hydrogen, N(H I), akin to gas clouds that give rise to Damped Lyman-alpha or Lyman Limit QSO absorption line systems (QSOALSs). This is particularly likely towards the gas-rich field UDG SECCO-dI-2 from which 21cm emission has recently been detected. This high N(H I) absorption, along with the corresponding metal absorption lines, will enable us to measure the ionization conditions of the ISM and CGM, its velocity structure, and especially its metallicity, which can be used to help constrain the chemical evolution of the galaxies and shed light on their origin. This will be the first study of absorption lines from this type of galaxies, and will demonstrate whether or not UDGs contribute significantly to the population of QSOALSs in the universe. The most important absorption lines from the intervening galaxies are Lyman-alpha and SiIII 1206. As the absorbing galaxies are at low redshift, these lines remain near geocoronal Lyman-alpha. We therefore need to use the remaining G130M-1291 grating settings. We also utilize the 2 remaining FP-POS positions to mitigate the effects of large-scale defects. There will now be a gap left between 1274-1294A which can no longer be filled using a different grating setting, but few absorption lines from the intervening galaxies are expected at these wavelengths.
