These range from understanding the properties of galaxies that contributed to cosmic reionization to the evolution of metal poor massive stars that give rise to the formation of heavy binary black holes. Crucial are observational constraints for the theoretical predictions, which can be obtained from rest-frame UV spectra of local star-forming dwarf galaxies with ionized-gas oxygen abundances at the low-metallicity threshold of the nearby Universe. While samples of UV spectra exist for galaxies in the metallicity range above 1/20 solar, only two useful spectra covering from H I Lyman-alpha (LyA, 1216 Ang) to C III] 1909 are available at lower metallicites. We propose COS G140L observations of eight extremely-metal poor galaxies (XMPGs) with He II emission that will: i) provide three more spectra with 12+log(O/H)=<7.4 (suitable targets at such low Z are hard to find), and ii) leverage existing WFC3 and Chandra images which are useful for discrimintating among different sources of ionization. Combining this dataset with existing spectra at similar and higher metallicity will allow us to address three questions: 1) How does metallicity determine galaxy properties?, 2) Is narrow He II emission a good tracer of peculiar massive stars?, and 3) Can we probe star-formation at high redshift with UV lines other than LyA? Our study will provide valuable clues for interpreting rest-frame UV spectra of high-z galaxies that will challenge our understanding of star formation at low Z. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use COS for our obsevations. Target acquisition. We will acquire de the targets via acq/image exposures of bandpass = 1700 - 3200 Ang. and pixel-scale=0.024" / pixel, using the NUV 15220( 7) - 25-May-2018 09:37:22 - [ 2] channel, PSA, and either mirror A or B, depending on the target's brightness. We require S/N = 5. Spectroscopy. We request G140L spectroscopy with cenwave = 1105 in order to cover the observed-frame wavelength range ~1121 to ~2148 Ang. at a spectral resolution of FWHM = 0.82 Ang. or 150 km/s at 1640 Ang. We plan to use: four focal plane positions in order to ensure the highest possible SNR; the flash = yes setting, and the time-tag mode. Orbits. We request one pointing per target. The number of orbits is driven by the requirement that SNR = 5 at 1640 * (1 + z), which corresponds to the observed wavelength of the He II 1640 line. This amounts to 9 orbits of HST. For the four targets with available G140L or G160M data, we calculate the number of orbits based on these data. For the rest of targets, we use a starburst99 (s99) model spectrum (SSP, 3 Myr, Z=0.001, no-rotation, high-mass loss) normalized to the AB magnitude in the U-band of SDSS DR12, or if available, the NUV AB magnitude of GALEX. The AB magnitudes correspond to similar pointings and apertures than COS. To each s99 model, we add a He II 1640 emission line with 10 times the reddening-corrected flux measured for the He II 4686 emission line using SDSS DR12 data. We then apply to s99 models the redshift and foreground reddening of the target. We use our spectra and standard background levels as input to the target acquisition and spectroscopic ETCs. For each target, the number of orbits equals the sum of the science exposure time, guide star + target acquisition times, and overhead time. This number takes into consideration the visibility times given in table 6.1 of HST's primer, which depend on the declination of the targets. In addition, for the first orbit of each visit, it includes: 6 min of guide star acquisition + 3 min of image target acquisition + 5 min of overhead for the first science exposure = 840 s. For subsequent orbits in the visit it includes: 4 min of guide star re-acquisition + 2 min for science exposures = 360 s. ------------------------------------------------------------------------------------ 15220( 7) - 25-May-2018 09:37:22 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SDSSJ104457.
