The 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 کاملThree-dimensional simulations of the interstellar medium in dwarf galaxies - I. Ram pressure stripping
We present 3D hydrodynamic simulations of ram pressure stripping in dwarf galaxies. Analogous studies on this subject usually deal with much higher ram pressures, typical of galaxy clusters, or mild ram pressure due to the gas halo of the massive galactic companions. We extend over previous investigations by considering flattened, rotating dwarf galaxies subject to ram pressures typical of poor...
متن کاملInterstellar 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 کاملThree-dimensional simulations of the interstellar medium in dwarf galaxies - II. Galactic winds
We study the hydrodynamical evolution of galactic winds in disky dwarf galaxies moving through an intergalactic medium. In agreement with previous investigations, we find that when the ram pressure stripping does not disrupt the ISM, it usually has a negligible effect on the galactic wind dynamics. Only when the IGM ram pressure is comparable to the central ISM thermal pressure the stripping an...
متن کاملThe interstellar medium of the Antennae Galaxies
To study the properties of the interstellar medium in the prototypical merging system of the Antennae galaxies (NGC 4038 and NGC 4039), we have obtained 12 CO (1–0), (2–1) and (3–2) line maps, as well as a map of the 870µm continuum emission. Our results are analysed in conjunction with data from X-ray to radio wavelengths. In order to distinguish between exact coincidence and merely close corr...
