Chemical inhomogeneities have been detected in the ionized gas of numerous SFGs via spatially resolved studies, with large implications for the flow of metals within and around galaxies. However, metals exist in multiple phases and, at present, the spatial distribution of metals throughout the neutral gas in SFGs remains unknown. Recent high-resolution galaxy-scale hydrodynamical simulations have made significant advancements, opening up crucial questions concerning mixing timescales and the presence of localized enrichment between the two gas phases. Answers can only be found by measuring both the neutral and ionized gas abundances along multiple identical sightlines throughout a nearby SFG. Here we propose COS G130M spectroscopy of 6 sightlines in NGC5253 (4 new, 2 archival), to measure the neutral gas abundances towards clusters ranging between 1-15Myr. When combined with ionized gas abundances of spatially matched spectra from VLT/MUSE, this unique dataset will provide the first spatially resolved study of metals both within and between two phases within a galaxy. Determining whether metal abundance offsets exist between the two phases, both globally and locally across a range of HII region properties, enables an exceptionally detailed sampling of chemical mixing scenarios and enrichment mechanisms experienced in SFGs. NGC5253's low-metallicity and high SFR make our findings applicable to both nearby and high-z SFGs. This remarkable study will provide the first observational test of multi-phase abundance patterns in cosmological simulations of dwarf galaxies. ------------------------------------------------------------------------------------ Observations Description ------------------------ Science overview: We propose to perform COS/FUV G130M/1291 and G130M/1222 spectroscopy of 4 pointings throughout a nearby, low-metallicity, star forming galaxy, NGC 5253. By combining this data with 2 pointings towards NGC 5253 from archival data (PIDs 11579, 15193), this dataset will allow us to map the neutral gas abundances towards 6 HII regions throughout NGC 5253. Furthermore, via in-hand optical integral field spectroscopic observations of NGC 5253 from VLT-MUSE, this unique dataset will offer the first spatially matched UV+optical 16240( 12) - 28-Oct-2022 14:44:27 - [ 2] spectroscopic study of a nearby SFG - enabling us to accurately compare the neutral and ionized gas abundances along the same sightline for a variety of stellar properties. Settings: We require G130M/1291 observations in order to cover the 1132-1433A spectral range. This provides access to a wide selection of ISM lines, required to determine the column densities of CII, NI, OI, SII, SiII, FeII, PII, while also covering the Lya region - essential in computing the neutral hydrogen column density (N(HI)) required for neutral gas abundances. We additionally request coverage of the 1070-1363A range using G130M/1222. This allows us to cover the FeIII 1122 line, required to calculate the ionization state of the gas via the FeIII/FeII line ratio. Sources: All targets are considered to be extended sources, with the exception of Cluster 8 For the pointings with multiple resolved clusters in the aperture (C9+10, C5+11) we have chosen an orient such that the clusters are separated in the cross-dispersion direction. Details are given in visit description boxes. For the pointing covering clusters 1+2+3+4, we will orient along 1+2+4, excluding cluster 3, to allow for the minimal amount of blending. For pointing coordinates, please use the HLSP data of NGC5253 (aligned to Gaia astrometry), which can be found at http://archive.stsci.edu/hlsp/ngc5253-dr2 ETCs: The COS spectroscopic ETC was used to estimate exposure times necessary to reach a S/N 7 at 1150A for G130M/1222 and G130M/1291. The flux of each target was normalized to the total observed flux that resides within the COS aperture, as measured on the HST/ACS/SBC/F125LP image (Table 1). For those pointings where several clusters are covered by the COS aperture, the flux corresponds to the average flux density across the aperture. BOP: The ETC reported no warnings for violations of the local and/or global bright object limits, so we expect the targets to be safe to observe. APT/BOT/GALEX gives local rate violation for one point (in PSA), global B exceeded with 1.86e4 counts/s. All counts rates are for GALEX GII magnitudes. All stars within the field are safe, as shown via ETCs for SCI, ACQ, and NUV imaging. A document with supporting information can be supplied to the CS. The same violation point was safely observed by Visit 06 of 15193 and in 11579. The spectroscopic exposures in each pointing will be executed with FP-split. TACQ: We will use the standard target acquisition (TA) strategy and perform ACQ/IMAGE TA with an ETC estimate to provide the (recommended) S/N 20. For pointings with multiple resolved clusters within the aperture, we will use affixed offset target acquisition from a nearby FUV-bright source, followed by a NUV image. ------------------------------------------------------------------------------------ 16240( 12) -
