Spanning the Reionization History of IGM Helium: a Large and Efficient HST Spectral Survey of Far-UV-Bright Quasars

Spanning the Reionization History of IGM Helium: a Large and Efficient HST Spectral Survey of Far-UV-Bright Quasars The reionization of IGM helium is thought to have occurred at redshifts of z=3 to 4. Detailed studies of HeII Lyman-alpha absorption toward a handful of QSOs at 2.7<z<3.3 demonstrated the high potential of such IGM probes, but the small sample size and redshift range limit confidence in cosmological inferences. The requisite unobscured sightlines to high-z are extremely rare, but we've cross-correlated 10,000 z>2.8 SDSS DR7 (and other) quasars with GALEX GR4 UV sources to obtain 550 new, high confidence, sightlines potentially useful for HST HeII studies; and in cycle 15-16 trials we demonstrated the efficacy of our SDSS/GALEX selection approach identifying 9 new HeII quasars at unprecedented 67% efficiency. We propose the first far-UV-bright HeII quasar survey that is both large in scale and also efficient, via 2-orbit reconnaissance ACS/SBC prism spectra toward a highly select subset of 40 new SDSS/GALEX quasars at 3.1<z<5.1. These will provide a community resource list that includes 5 far-UV-bright (restframe) HeII sightlines in each of 8 redshift bins spanning 3.1<z<3.9 (and perhaps several objects at z>4), enabling superb post-SM4 follow-up spectra with COS or STIS. But simultaneously and independent of any SM4 uncertainties, we will hereby directly obtain 10-orbit UV spectral stacks from the 5 HeII quasars in each of the 8 redshift bins to trace the reionization history of IGM helium over at least 3.1<z<3.9. These spectral stacks will average over cosmic variance and individual object pathology. Our new high-yield HeII sightline sample and spectral stacks, covering a large redshift range, will allow confident conclusions about the spectrum and evolution of the ionizing background, the evolution of HeII opacity, the density of IGM baryons, and the epoch of helium reionization.

40 quasars at z>3.1 selected from SDSS, VCV, and GALEX will be observed (2 orbits each) using ACS/SBC PR130L to spectroscopically explore and confirm detected GALEX broadband UV flux detection down to the HeII Lyman-alpha break. Two dither positions are used, with direct images at each to obtain wavelength calibration for the prism exposures. The last prism exposure in each other may be adjusted in length to fill the orbit. (Alternate targets may be available if some included here are at poor positions for Cycle 16 Supplemental observations). UV OVERLIGHT SAFETY FOR SBC: Quality ultraviolet overlight safety data information is available based on GALEX UV broadband imaging photometry for each target/field in this program. (5-band SDSS imaging photometry is also available in the optical for most targets/fields, though of course the optical is not as good as the GALEX images for directly confirming UV overlight saftely). We have thus examined the GALEX catalogs, and also visually inspected the GALEX images by eye, for each quasar/field to help ensure overlight safety. The direct F150LP ultraviolet images needed for wavelength calibration are the most sensitive in this progam, and are the driving concern for our SBC overlight considerations; the prism science spectral exposures with PR130L, of course, have far lower count rates than the direct SBC images. For program-wide overlight saftely considerations, we start by very conservatively assuming a maximum bright safety limit in the SBC of <20 counts/sec/pixel through F150LP; note that this conservatively is already 2.5X below the standard 50 counts/s/pixel SBC limit to allow for unusual variable sources. We use the ETC, adopting a power-law (e.g. quasar) spectrum of UV slope 0.5, and convert this SBC count rate limit into equivalent GALEX safe flux limits of <3.7e-15 erg/s/cm^2/A in the NUV and <6.2e-15 erg/s/cm^2/A in the FUV; the latter correspond to AB magnitude limits through F150LP of m(NUV)>16.9 and m(FUV)>17.2 in order to ensure SBC/F150LP count rates of <20 counts/sec/pixel. For direct comparison, we report in the comments for each target in this program both: (1) the quasar/target GALEX magnitudes in both FUV and NUV bands (a GALEX magnitude entry of 'not detected' denotes a GALEX non-detection, but there is GALEX data in each GALEX filter in each case); and, (2) the brightest UV sources in both FUV and NUV GALEX images within 35" of the quasar/target to ensure overlight safety from all other individual UV sources in the SBC FOV. In summary for the entire program, the very brightest NUV GALEX source in all 40 fields around all 40 targets is m(NUV)=19.35, and the very brightest FUV GALEX source in all 40 fields around all 40 targets is m(FUV)=19.59. Thus, the very brightest GALEX source in all 40 fields is conservatiely 2.4 mags, or nearly an order of magnitude, fainter than the above already conservative <20 counts/sec/pixel bright safety limit for SBC/F150LP (for a highly variable, quasar). As a final similar double-check we used the GALEX images for each field to ensure that there are no plausible violations (by multiple orders of magnitude) of the global SBC 80,000 cts/sec level in the entire SBC field. We added up the GALEX NUV and FUV fluxes of all detected GALEX sources in each field for all 40 targets. Even in the brightest such field considered from this perspective, the predicted total SBC/F150LP global field count rate from GALEX sources (using the ETC and input spectrum as above) is <20 cts/sec globally, considering both GALEX NUV and FUV data.
