QSO Absorption Line Systems from Dwarf Galaxies

QSO Absorption Line Systems from Dwarf Galaxies We propose observing 6 QSOs who sightlines pass within 14 kpc of nearby (cz ~ 400-3300 km/s) faint [M_B = -15.3 to -17.7] blue dwarf galaxies, in order to study the UV absorption lines arising from the disks and halos of the dwarfs. Low mass, gas-rich galaxies are expected to have a pivotal role in providing feedback mechanisms for regulating galaxy evolution, and for enriching the intergalactic medium (IGM). Our observations are designed to answer a simple set of questions, including: do outflows exist from the majority of low mass galaxies, and how far do the halos extend before merging with the IGM? What are the kinematics of the warm diffuse gas, and are the bulk velocities sufficient for the gas to escape from the potential wells of the galaxies? What are the metallicities of the outflows, and are they high enough to significantly effect the metallicity of the IGM? Do the metallicities of the outflows agree with measurements from HII regions within the galaxy itself? And how do the characteristics of the absorption lines compare with the family of QSO Absorption Line Systems seen at high redshifts? That is, do dwarf galaxies contribute significantly to the population of absorbers at earlier epochs? Our aim is to use the G130M of COS to search for absorption lines along QSO sightlines that pass close to low-redshift dwarf galaxies. In all cases, we can predict the wavelengths at which particular absorption lines are expected, given the redshift of an intervening galaxy, and select the central wavelength of a grating, along with its associated FP-POS positions, to cover those lines. Not all FP-POS positions are used if important lines are not covered as a result. In general, two central wavelength settings are used to cover the gap that comes from a single central wavelength setting (though at a reduced S/N). All targets have known GALEX FUV and NUV mags. A S/N of ~14 per resolution element is expected based on the FUV magnitude in the G130M spectra.
