PI: Dr. David V. Bowen Princeton University Y CoI: Prof. Todd M. Tripp University of Massachusetts - Amherst N CoI: Prof. Max Pettini University of Cambridge N ------------------------------------------------------------------------------------ Abstract We propose a COS G130M program to measure the gas-phase metallicities of the cool neutral medium in 5 "extremely metal poor galaxies", or XMPGs. We have selected the XMPGs to have emission line metallicities, Z_emm, in the range 12+log(O/H) = 7.1 to 7.5, or 1/40th to 1/16 times the solar metallicity. The COS spectra of the UV-bright regions in the galaxies will record, in particular, Lyman-alpha, SII, PII, NI, CII and OI absorption lines, which can be used to derive accurate column densities and therefore abundances and abundance ratios. We aim to test how much less the metallicity of the neutral medium, Z_abs, can be, compared to Z_emm, a difference that is seen in higher metallicity star-forming galaxies. We also aim to provide accurate N/O and alpha/O abundance ratios in the XMPGs' neutral gas from which to investigate their star formation histories. Two unique galaxies are targeted, DDO 68, which is one of the lowest metallicity galaxies known, and SBS 0940+544, a galaxy where Z_emm drops by a dex over a transverse length of only 400 pc. Confirming differences in Z_abs and Z_emm in XMPGs will show that the baseline metallicity for the canonical stellar-mass to metallicity relationship should use Z_abs instead of Z_emm in galaxy evolution modelling. We will also use our data to explore whether XMPGs could be the progenitors of young galaxies seen by the damped Lyman-alpha absorption systems detected towards background QSOs, or whether the origin of the latter population still needs to be properly explained. ------------------------------------------------------------------------------------ Observations Description ------------------------ Our aim is to observe the brightest regions of the selected XMPGs with the COS G130M grating to record Lyman-alpha absorption and metal absorption lines from the interstellar gas in and around the galaxy. The galaxies range in redshift from ~ 500 - 3600 km/s, so, e.g., Lyman-alpha lies between 1218-1230A. 3 of 5 sightlines have been observed by COS before, either at lower resolution with the G140L grating, or at longer wavelengths (e.g. with the G185M grating), so information already exists on UV fluxes and previous ACQ exposure times. These are discussed in this Phase 2 for each object individually. UV fluxes for the remaining 2 sightlines are extrapolated from optical SDSS spectra. For all sightlines, we use the 2 FP-POS settings allowed for the grating centered at 1291A, a wavelength which is essential for observing the Lyman-alpha absorption. For one sightline (DDO68-1), one of the 2 visits needs to be spent in SHADOW, in order to resolve the Lyman-alpha absorption line profile from strong geocoronal Lyman-alpha emission. 16227( 3) - 21-Jun-2021 15:02:08 - [ 2] ------------------------------------------------------------------------------------ 16227( 3) - 21-Jun-2021 15:02:08 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 DDO68-1 EXT-CLUSTER, STAR RA=09H56M46.8000S +/- 0.3", J2000 V = 503 V = 15.9 +/- 0.1 FUV(1460) flux = FORMING REGION DEC=+28D50'10.50" +/- 0.3" 1.0e-15 ergs/cm^2/s/A (based on previous COS G160M data) Reference Frame: ICRS Extended: YES Comments: The position of the star-forming region is based on the previous COS observations (P13788) and agrees with (a) its position on the WFC3 UVIS F275W image retrieved from the Hubble Legacy Archive, and (b) its position on the 22 sec MIRROR-B ACQ/IMAGE exposure used to acquire the object in P13788 (lcne01qzq_flt.fits). ------------------------------------------------------------------------------------------------------------------------------------ 2 SBS1159+545 EXT-CLUSTER, STAR RA=12H02M2.4940S +/- 0.1", J2000 V = 3600 V = 18.7 +/- 0.1 F(1220) = 1.3e-15 FORMING REGION DEC=+54D15'51.00" +/- 0.1" ergs/cm^2/s/A Reference Frame: ICRS Extended: YES Comments: The position of the star-forming region is measured from a 160sec COS MIRROR-A ACQ image (ldaf03pxq_flt.fits) taken as part of P14628 for a COS G140L observation.
