Interstellar Medium Oxygen Abundances of Dwarf Irregular Galaxies in Centaurus A and Nearby Groups⋆
We present results of optical spectroscopy of 35 H II regions from eight dwarf galaxies in the Centaurus A group. [O III] λ4363 is detected in ESO272−G025 and ESO324−G024, and direct oxygen abundances of 12+log(O/H) = 7.76 ± 0.09 and 7.94±0.11 are derived, respectively. For the remaining galaxies, abundances are derived using common bright-line methods. To compare the influence of group environ...
متن کاملThe Violent Interstellar Medium of Nearby Dwarf Galaxies
High resolution H i observations of nearby dwarf galaxies (most of which are situated in the M81 group at a distance of about 3.2Mpc) reveal that their neutral interstellar medium (ISM) is dominated by hole–like features most of which are expanding. A comparison of the physical properties of these holes with the ones found in more massive spiral galaxies (such as M31 and M33) shows that they te...
متن کاملNebular Abundances of Nearby Southern Dwarf Galaxies
The results of optical spectroscopy of H II regions in a sample of southern dwarf irregulars consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor group, and eight additional dwarf galaxies are presented. Oxygen abundances are derived using the direct method where [O III]λ4363 is detected; otherwise, abundances are derived with the bright-line method using the ...
متن کاملDwarf Irregular Galaxies and the Intergalactic Medium
Dwarf galaxies (DGs) are more numerous than large galaxies. Most dwarfs in clusters are dEs, but in the field they belong mostly to late types. The importance of late-type DGs in the context of the intergalactic medium (IGM) lies in the fact that (at least some) are probably " young " galaxies forming stars for the first time. Many DGs have significant amounts of interstellar gas, they may form...
متن کاملISM Abundances in Sculptor Group Dwarf Irregular Galaxies
Using the CTIO 4-m telescope, we have obtained optical spectra of HII regions in five Sculptor Group dwarf irregular galaxies. We derive oxygen, nitrogen, and sulfur abundances from the HII region spectra. Oxygen abundances are derived via three different methods (the “direct” method, the empirical method guided by photoionization modeling of McGaugh (1991), and the purely empirical method of P...
