Spatially Resolved Spitzer-IRS Spectroscopy of the Central Region of M82
P. Beirão, B. R. Brandl, P. N. Appleton +6
We present high spatial resolution (~ 35 parsec) 5-38 um spectra of the central region of M82, taken with the Spitzer Infrared Spectrograph. From these spectra we determined the fl…
Probing Star Formation in Interacting Galaxies Using UV and Mid-IR: The Case of Arp 82
M. Hancock, B. J. Smith, C. Struck +4
To help understand the effects of galaxy interactions on star formation, we analyze Spitzer infrared and GALEX ultraviolet images of the interacting galaxy pair Arp 82 (NGC 2535/6)…
Spitzer Observations of Deeply Obscured Galactic Nuclei
H. W. W. Spoon, J. V. Keane, J. Cami +4
We report on our first results from a mid-infrared spectroscopic study of ISM features in a sample of deeply obscured ULIRG nuclei using the InfraRed Spectrograph (IRS) on the Spit…
First mid-infrared spectrum of a faint high-z galaxy: Observations of CFRS 14.1157 with the Infrared Spectrograph on the Spitzer Space Telescope
S. J. U. Higdon, D. Weedman, J. L. Higdon +7
The unprecedented sensitivity of the Infrared Spectrograph on the Spitzer Space Telescope allows for the first time the measurement of mid-infrared spectra from 14 to 38 microns of…
Rest-Frame MIR Detection of an Extremely Luminous Lyman Break Galaxy with the Spitzer IRS
H. I. Teplitz, V. Charmandaris, L. Armus +9
We present the first rest-frame ~4 micron detection of a Lyman break galaxy. The data were obtained using the 16 micron imaging capability of the Spitzer Infrared Spectrograph. The…
The Extraordinary Mid-infrared Spectrum of the Blue Compact Dwarf Galaxy SBS0335-052
J. R. Houck, V. Charmandaris, B. R. Brandl +8
SBS0335-052 is a blue compact dwarf galaxy (BCD) with one of the lowest known metallicities, ZZ$_{\sun}$/41, making it a local example of how primordial starburst galaxies an…
