The Difference Between Neutral- and Ionized-Gas Metal Abundances in Local Star-Forming Galaxies with COS

This is a re-submission of our previous Phase II. This proposal now contains Visit 32 - a copy of the previously failed Visit 31 but with corrected target coordinates, as specified for Target 32 (NGC4214-REVISIT). ----- Attempting Submission 7 (Wed Feb 03 19:20:27 GMT 2010) ----- ----- Attempting Submission 8 (Thu Sep 30 15:52:50 GMT 2010) ----- These errors can be disregarded since they are related to completed visits. The Difference Between Neutral- and Ionized-Gas Metal Abundances in Local Star-Forming Galaxies with COS The metallicity of galaxies and its evolution with redshift is of paramount importance for understanding galaxy formation. Abundances in the interstellar medium (ISM) are typically determined using emission-line spectroscopy of HII regions. However, since HII regions are associated with recent SF they may not have abundances typical for the galaxy as a whole. This is true in particular for star-forming galaxies (SFGs), in which the bulk of the metals may be contained in the neutral gas. It is therefore important to directly probe the metal abundances in the neutral gas. This can be done using absorption lines in the Far UV. We have developed techniques to do this in SFGs, where the absorption is measured for sightlines toward bright SF regions within the galaxy itself. We have successfully applied this technique to a sample of galaxies observed with FUSE. The results have been very promising, suggesting in I Zw 18 that abundances in the neutral gas may be up to 0.5 dex lower than in the ionized gas. However, the interpretation of the FUSE data is complicated by the very large FUSE aperture (30 arcsec), the modest S/N, and the limited selection of species available in the FUSE bandpass. The advent of COS on HST now allows a significant advance in all of these areas. We will therefore obtain absorption line spectroscopy with G130M in the same sample for which we already have crude constraints from FUSE. We will obtain ACS/SBC images to select the few optimal sightlines to target in each galaxy. The results will be interpreted through line-profile fitting to determine the metal abundances constrained by the available lines. The results will provide important new insights into the metallicities of galaxies, and into outstanding problems at high redshift such as the observed offset between the metallicities of Lyman Break Galaxies and Damped Lyman Alpha systems.

We will perform COS/FUV spectroscopy of several point-like sources within 9 nearby star-forming galaxies previously observed with FUSE. We will infer the abundances of the neutral ISM for a more direct comparison with the abundances in the H II regions. The G130M grating at the central wavelength 1291 Ang will be used to cover the 1132-1274 and 1291-1433 Ang spectral range. The spectroscopic exposures in each pointing will be executed with FP-split to mitigate flat-fielding uncertainties and improve the S/N. Since the targets of each pointing will be faint point-like sources we will perform a standard peak-up target acquisition (TA) in NUV imaging mode. We will start our observing campain by performing 1-orbit FUV imaging of each galaxy with a set-up which includes as much as possible of the wavelength range that we are interested in, i.e., ACS/SBC with F125LP. (For SBS 0335-052 an ACS/SBC F140LP archival image already exists that we can use as early-acquisition image.) The FUV image will be used as early-acquisition image for spectroscopy and will be crucial to guide the COS pointing. The spectroscopy of each galaxy should occur no earlier than 3 months after the acquistion of the ACS/SBC galaxy image. We will inspect our ACS/SBC images to find target sources that are bright enough for absorption line spectroscopy, as compact as possible, and no larger than ~1 arcsec in diameter, in order to achieve a spectral resolution that will allow us to perform the necessary neutral ISM analysis. Having at least 3 sightlines per galaxy is useful in order to understand and calibrate out spatial dependences and variations of the metal abundances within the galaxy. However, this can only be done efficiently for the closest (D < 10 Mpc) SFGs which are also better resolved in terms of stellar clusters and SF regions. We thus plan for only one sightline for the most distant galaxies in the sample. This is reflected in our Phase II. However, the exact number of pointings and orbits per galaxy, and the exact coordinates (right ascension and declination) of the pointings, will be modified and finalized after the imaging has been obtained.
