Measurements of He I λ5876 Recombination Line Radiation from the Diffuse, Warm Ionized Medium in Irregular Galaxies
We present longslit optical spectroscopy of three high surface brightness Magellanic irregular galaxies. This paper draws attention to our detection of He I λ5876 line emission from the ionized gas outside the HII regions, or the warm ionized phase of the interstellar medium. We measure a mean reddening-corrected intensity ratio of He I λ5876 / Hα ≈ 0.041 independent of spatial location. This r...
متن کاملThe warm ionized medium in spiral galaxies
This article reviews observations and models of the diffuse ionized gas that permeates the disk and halo of our Galaxy and others. It was inspired by a series of invited talks presented during an afternoon scientific session of the 65th birthday celebration for Professor Carl Heiles held at Arecibo Observatory in August 2004. This review is in recognition of Carl’s long standing interest in and...
متن کاملThe Survey for Ionization in Neutral-gas Galaxies: Iii. Diffuse, Warm Ionized Medium and Escape of Ionizing Radiation
We use the first data release from the SINGG Hα survey of H I-selected galaxies to study the quantitative behavior of the diffuse, warm ionized medium (WIM) across the range of properties represented by these 109 galaxies. The mean fraction fWIM of diffuse ionized gas in this sample is 0.59±0.19, slightly higher than found in previous samples. Since lower surface-brightness galaxies tend to hav...
متن کاملThe Warm Ionized Medium in Spiral Galaxies: A View from Above
The Warm Ionized Medium (WIM), also refered to as Diffuse Ionized Gas, contains most of the mass of interstellar medium in ionized form, contributing as much as 30% of the total atomic gas mass in the solar neighborhood. The advent of CCDs has enabled unprecedented study of this medium in external galaxies, probing a variety of environments. In particular, we can derive the morphology of the WI...
متن کاملEvidence for an Additional Heat Source in the Warm Ionized Medium of Galaxies.
Spatial variations of the [S ii]/Halpha and [N ii]/Halpha line intensity ratios observed in the gaseous halo of the Milky Way and other galaxies are inconsistent with pure photoionization models. They appear to require a supplemental heating mechanism that increases the electron temperature at low densities, ne. This would imply that in addition to photoionization, which has a heating rate per ...
