Assigned ID: 877 ----- Attempting Submission 1 (Sat Feb 26 00:53:44 GMT 2011) ----- ----- Attempting Submission 1 (Fri Jul 08 19:31:44 GMT 2011) ----- Technically, using all four FP-POS positions is preferable for fixed pattern noise issues. However, given that most of our Visits are only one orbit in duration, we don't think it's worth the additional overhead. We will be heavily binning our data anyway, so issues regarding the COS LSF and fixed pattern noise won't be as important as if we were using native resolution. A Survey of Atomic Hydrogen at 0.2 < z < 0.4 Presently, the role of cool gas in galaxy evolution is poorly constrained by observations. 21cm studies map HI in the very local Universe, but not to cosmological distances, and while many data exist for damped Ly-alpha (DLA) absorbers at z>2, the limitations at high-z make their interpretation difficult. Redshifts z<1.65 were finally probed in our HST cycles 6, 9 and 11 Ly-alpha absorption surveys, and using MgII absorbers through our surveys in the SDSS quasar spectra and our own MMT survey. While these works have contributed greatly to our understanding of cool gas in galaxies across the past ~10Gyrs, the lowest redshifts - where there exists the potential to connect the results from high-z absorption-based studies to that of local emission-based work - remain poorly probed. Thus we propose to obtain COS FUV spectra of 19 known MgII absorption systems at 0.2<z<0.4 to determine their HI column densities. We expect to double the number of classically-selected DLAs and subDLAs in this redshift range. Our targets have known, relatively bright FUV magnitudes and are screened for higher-z absorption systems which could absorb flux at the location of our target Ly-alpha line. Thus we expect a ~100% success rate at detecting and measuring high column density HI systems. In addition to measuring the cosmic density of HI at an epoch intermediate to current high-z and local measurements, these observations will provide unique and invaluable laboratories that can provide constraints on our understanding of metal-line absorbers, cool-gas accretion, processes involving the reservoirs of gas for star formation, and galactic-outflows/IGM-enrichment.
We have proposed to obtain COS FUV spectra of 19 QSOs with strong Mg II absorbers at 0.197 < z_abs < 0.404 to expand the sample of high-NHI systems at z < 0.4, for which only seven damped Lyman alpha systems (DLAs; four discovered with STIS and three with COS) and four subDLAs are currently known. We eliminated any objects with higher-z Mg II systems that could produce Lyman limit systems in their own right (thereby absorbing the quasar flux at the position of the targeted Ly-alpha line), as well as objects with GALEX FUV magnitudes > 20, leaving us with our final target list. While high spectral resolution is not required to accurately determine NHI for (sub)DLAs, we have chosen to exploit the greater sensitivity of the medium-resolution COS/FUV grat ings (as compared to G140L) and bin heavily to increase S/N. Since all of the Mg II absorbers are located at z_abs > 0.197, the corresponding Ly-alpha absorption will be redshifted into the G160M band for all of our targets. Exposure times were calculated to reach S/N 3 per G160M resolution element at the redshifted wavelength of Ly-alpha using the COS Spectroscopic Exposure Time Calculator, which corresponds to S/N > 10 when binned to R = 2,000. As we have: (i) confirmed the UV brightness of the targets via GALEX data, and (ii) inspected our QSO spectra to confirm the absence of higher-z intervening low-ion absorption systems whose redshifted Ly-limit could absorb the UV flux at the wavelength of the target Ly-alpha, we expect a 100% success rate at being able to determine NHI with our observations.

CASM was run in Phase II mode. Since AGN are variable targets, some care was taken in choosing a target acquisition strategy. All of our targets are faint enough that they require NUV imaging target acquisitions with the PSA. To determine whether MIRRORA or MIRRORB is appropriate, we assume that the target is twice as bright (NUV - 0.8 mag) as its GALEX flux would suggest. If the target is safe for MIRRORA observations at this heightened brightness, then MIRRORA is chosen, otherwise we choose MIRRORB. To determine the proper integration time we assume that the target is only half as bright (NUV + 0.8 mag) as its GALEX flux would suggest and time the acquisition exposure to reach S/N=30 at this diminished brightness. The coordinates of our targets are generally known to better than 0.1 arcsec, so we forgo the ACQ/SEARCH sequence and only perform an ACQ/IMAGE. However, the coordinates for Target 1 are less trustworthy so we perform a 2x2 ACQ/SEARCH before the final ACQ/IMAGE. All exposure time calculations were performed using the FOS-based QSO template redshifted to the target redshift and reddened by the GALEX-determined E(B-V). The template spectra were normalized to the target's GALEX NUV magnitude (+- 0.8 mag as described above) for target acquisitions and its GALEX FUV magnitude for spectroscopic exposures. The G160M/1600 setting was chosen unless the targeted Lya wavelength was located near the gap between segments, and average background and airglow values were assumed. All targets are observed long enough to reach S/N > 2.5 per resolution element at the wavelength of the expected Lya absorption. We will bin to lower spectral resolution to increase S/N before performing any line fits. All exposures are cleared by the GALEX BOT, and since only COS NUV target acquisitions and FUV spectra are being obtained we ignore the GSC-II BOT warnings.
