The Interstellar Medium of Star-forming Irregular Galaxies: The View with ISO
D. Hunter, M. Kaufman, D. Hollenbach +8
We present mid-infrared imaging and far-infrared (FIR) spectroscopy of 5 IBm galaxies observed by ISO as part of our larger study of the inter- stellar medium of galaxies. Most of…
Evidence for the Heating of Atomic Interstellar Gas by PAHs
George Helou, Sangeeta Malhotra, David J. Hollenbach +2
We report a strong correlation between the [CII] 158 micron cooling line and the mid-infrared flux in the 5-10 micron range in a wide variety of star-forming galaxies. The mid-infr…
Extended [C I] and ^{13}CO(5-4) Emission in M17SW
J. E. Howe, M. L. N. Ashby, E. A. Bergin +19
We mapped a 13 by 22 pc region in emission from 492 GHz [C I] and, for the first time, 551 GHz ^{13}CO(5-4) in the giant molecular cloud M17SW, using the Submillimeter Wave Astrono…
Probing the Interstellar Medium in Early type galaxies with ISO observations
S. Malhotra, D. Hollenbach, G. Helou +9
Four IRAS-detected early type galaxies were observed with ISO. With the exception of the 15 micron image of NGC1052, the mid-IR emission from NGC1052, NGC1155, NGC5866 and NGC6958…
Mid-Infrared Observations of Normal Star-Forming Galaxies: The Infrared Space Observatory Key Project Sample
Daniel A. Dale, Nancy A. Silbermann, George Helou
We present mid-infrared maps and preliminary analysis for 61 galaxies observed with the ISOCAM instrument aboard the Infrared Space Observatory. Many of the general features of gal…
Photoionization of Galactic Halo Gas by Old Supernova Remnants
Jonathan D. Slavin, Christopher F. McKee, David J. Hollenbach
We present new calculations on the contribution from cooling hot gas to the photoionization of warm ionized gas in the Galaxy. We show that hot gas in cooling supernova remnants (S…
