PI: Prof. Daniel P. Stark University of Arizona Y CoI: Peter Senchyna University of Arizona N CoI: Dr. Jacopo Chevallard CNRS, Institut d'Astrophysique de Paris N CoI: Prof. Tucker Jones University of California - Davis N CoI: Dr. Stephane Charlot CNRS, Institut d'Astrophysique de Paris N ------------------------------------------------------------------------------------ Abstract The first glimpse of the spectral properties of z~7-10 galaxies has recently emerged. Deep UV spectra have revealed intense emission from nebular CIII] and CIV, implying a hard radiation field that is rarely seen at lower redshifts. Unfortunately, we are currently unprepared to interpret these features, owing to shortcomings in our understanding of the radiation field powered by low metallicity stellar populations. Recent work with HST/COS in the local universe has provided a way forward, unveiling four nearby metal poor galaxies with UV nebular line spectra approaching those seen at z>7. The discovery of these galaxies opens the door for the first comprehensive investigation of the low metallicity stellar populations that likely dominate at z>7. Here we propose to obtain ultra-deep (10 orbit) COS/G160M spectra capable of measuring stellar photospheric and wind absorption features in these four galaxies. The data will provide the first quantitative constraints on the metallicity of massive stars required to power the hard radiation fields implied by the nebular lines and will allow us to investigate whether the stellar metallicity (sensitive to iron) departs from the metallicity of the nebular gas (sensitive to oxygen) in the extreme UV line emitters. Using new spectral tools, we will simultaneously fit the stellar absorption features and nebular lines, providing a powerful stress test of population synthesis models at low metallicity. If this UV spectral database is not obtained while COS is still functioning, the interpretation of reionization era galaxy spectra will be severely jeopardized throughout the JWST era. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain deep medium-resolution FUV COS spectroscopy for four metal-poor star-forming galaxies previously identified as high-ionization nebular line emitters with shallow UV spectroscopy. All four have already been observed with HST/COS, which also confirm each are dominated by easily-acquired compact star-forming regions bright in the UV (FUV<19). We will utilize the same acquisition strategy adopted previously: using an NUV ACQ/IMAGE exposure initially centered on the SDSS-derived ICRS coordinates of the bright knot. We adopt the Mirror A ACQ/IMAGE exposure times successfully used previously. The spectroscopic observations will be conducted in the G160M/1533 grism setting which covers the stellar photospheric and wind features we are targeting at the 15646( 4) - 30-Oct-2019 14:07:39 - [ 2] redshifts of the selected galaxies. Exposures will be taken in the TIME-TAG mode in all four focal positions for each object. Observations are split into two 5-orbit blocks per object for optimal scheduling, and each orbit is devoted to a single science exposure with buffer dumps occurring during occultation. ETC estimates indicate that the combined exposures will exceed an S/N of 15 per resolution element, sufficient to detect the faint stellar features we proposed to measure. ------------------------------------------------------------------------------------ 15646( 4) -
