Download or read book The Physical Properties in the Interstellar Medium of Low-metallicity Dwarf Galaxies written by Diane Cormier and published by . This book was released on 2012 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the framework of galaxy evolution, local star-forming dwarf galaxies are ideal laboratories to study star formation processes at low metallicity and the role of metal enrichment on the physical conditions. My thesis has focused on the study of the gas properties of the dwarf galaxies from "The Herschel Dwarf Galaxy Survey", combining observations and modeling efforts. I have investigated the role of the most important tracers of the multi-phase the interstellar medium (ISM), in the mid-infrared to submillimeter range. Particular attention was paid to the ionized and neutral gas coolants observed with Herschel Space Observatory (e.g. [OIII] 88, [OI]63, [CII] 157 micron lines), and to the CO molecule, probing the molecular phase, with complementary ground-based observations. The data are interpreted in physical terms (density, radiation field, filling factors) with radiative transfer models. This work has helped elucidate the structure and conditions of the low-metallicity ISM. It highlights the porosity of the ISM of dwarf galaxies, with ultraviolet photons from the massive star-forming regions excitinig the gas out to large distances. This results in the presence of large volume filling factor diffuse ionized/neutral gas, clumpy photodissociation regions, and little observed molecular gas due to large-scale photodissociation.

Download or read book Constraining the Properties of the Metal-poor ISM with Interferometric CO Observations of Low Metallicity Dwarf Galaxies written by Edward M. Molter and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal deficient dwarf galaxies are critical test beds for theories about the structure of star forming clouds at low metallicity, the chemical evolution of the inerstellare medium, and the conditions in the early Universe. I present new high-resolution interferometric observations of the CO (J=1{right arrow] 0) emission line in five nearby metal poor dwarf irregular dwarf galaxies taken with the CARMA array. The first half of this work considers four galaxies with very extreme metaliicites (3-10% Solar), including Leo P, DDO 68, Sextans B. While CO was not detected in any of these systems, we are able to derive very sensitive upper limits to their global CO luminosities, calculate molecular hydrogen masses using various CO-to-H2 conversion factors, and compare these results to chemical evolution models. The second half of this work consists of a case study on the interstellar medium of NGC 6822, a famous Local Group dwarf irregular galaxy at ~30% of Solar metallicity. CARMA resolves ten individual clouds of dense CO emission at ~10 pc linear scales in a central region of the galaxy\. CO luminosities and derived H2 masses are presented for each cloud, and the cloud properties are compared to similar observations in the literature. I then leverage data at a myriuad of wavelenghts to draw spatial comparisons between the distributions of dense molecular gas, atomic gas, and dust at various temperatures.
