High resolution spectra of the Spitzer Space Telescope show vibration-rotation absorption bands of gaseous C2H2, HCN, and CO2 molecules toward a sample of deeply obscured (U)LIRG n…
Mid-IR Galaxy Classification Based on Silicate Obscuration and PAH Equivalent Width
H. W. W. Spoon, J. A. Marshall, J. R. Houck +5
We present a new diagnostic diagram for mid-infrared spectra of infrared galaxies based on the equivalent width of the 6.2 micron PAH emission feature and the strength of the 9.7 m…
An Ultraviolet-to-Radio Broadband Spectral Atlas of Nearby Galaxies
D. A. Dale, A. Gil de Paz, K. D. Gordon +28
The ultraviolet-to-radio continuum spectral energy distributions are presented for all 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). A principal component ana…
Mid-Infrared Spectroscopy of High Redshift Submillimeter Galaxies: First Results
Karín Menéndez-Delmestre, Andrew W. Blain, Dave M. Alexander +6
We present mid-infrared spectra of 5 submillimeter galaxies at z=0.65-2.38 taken with the Spitzer Space Telescope. Four of these sources, at z<1.5, have strong PAH features and the…
Optical spectroscopy and X-ray detections of a sample of quasars and AGN selected in the mid-infrared from two Spitzer wide-area surveys
M. Lacy, A. Petric, A. Sajina +5
We present optical spectroscopy of a sample of 77 luminous AGN and quasars selected on the basis of their mid-infrared colors. Our objects are selected from the Spitzer Extragalact…
Relating Diffusion Properties of Cosmic-Ray Electrons to Star Formation Activity within Normal Galaxies
E. J. Murphy, G. Helou, L. Armus +3
Using data obtained as part of the {\it Spitzer} Infrared Nearby Galaxies Survey (SINGS; Kennicutt et al. 2003) and WSRT-SINGS radio continuum survey (Braun et al. 2006), we study…
