Searching for hidden Wolf-Rayet stars in the Galactic Plane - 15 new Wolf-Rayet stars
L. J. Hadfield, S. D. Van Dyk, P. W. Morris +3
We report the discovery of fifteen previously unknown Wolf-Rayet (WR) stars found as part of an infrared broad-band study of candidate WR stars in the Galaxy. We have derived an em…
Characterizing Young Brown Dwarfs using Low Resolution Near-IR Spectra
K. N. Allers, D. T. Jaffe, K. L. Luhman +7
We present near-infrared (1.0-2.4 micron) spectra confirming the youth and cool effective temperatures of 6 brown dwarfs and low mass stars with circumstellar disks toward the Cham…
The Mid-Infrared Spectrum of Star-Forming Galaxies: Global Properties of PAH Emission
J. D. T. Smith, B. T. Draine, D. A. Dale +15
We present a sample of low-resolution 5-38um Spitzer IRS spectra of the inner few square kiloparsecs of 59 nearby galaxies spanning a large range of star formation properties. A ro…
Spitzer IRAC Images and Sample Spectra of Cassiopeia A's Explosion
J. A. Ennis, L. Rudnick, W. T. Reach +5
We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most se…
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…
The Effect of Star Formation on the Far-Infrared--Radio Correlation within Galaxies
E. J. Murphy, G. Helou, R. Braun +13
Using data obtained for twelve galaxies as part of the {\it Spitzer} Infrared Nearby Galaxies Survey (SINGS) and the Westerbork Synthesis Radio Telescope (WSRT)-SINGS radio continu…
Far-infrared characterization of an ultra-luminous starburst associated with a massively-accreting black hole at z=1.15
E. Le Floc'h, C. N. A. Willmer, K. Noeske +25
As part of the "All Wavelength Extended Groth Strip International Survey" (AEGIS), we describe the panchromatic characterization of an X-ray luminous active galactic nucleus (AGN)…
Discovery of a Young Substellar Companion in Chamaeleon
K. L. Luhman, J. C. Wilson, W. Brandner +6
During an imaging survey of the Chamaeleon I star-forming region with the ACS aboard HST, we have discovered a candidate substellar companion to the young low-mass star CHXR 73 (~2…
Spatially Resolved Spitzer Spectroscopy of the Starburst Nucleus in NGC 5253
P. Beirao, B. R. Brandl, D. Devost +3
We present new Spitzer Space Telescope data on the nearby, low-metallicity starburst galaxy NGC 5253, from the Infrared Array Camera IRAC and the Infrared Spectrograph IRS. The mid…
The opaque nascent starburst in NGC 1377: Spitzer SINGS observations
H. Roussel, G. Helou, J. D. Smith +16
We analyze extensive data on NGC1377 from the Spitzer Infrared Nearby Galaxies Survey (SINGS). Within the category of nascent starbursts, that we previously selected by their infra…
Mid-Infrared Spectral Diagnostics of Nuclear and Extra-Nuclear Regions in Nearby Galaxies
D. A. Dale, J. D. T. Smith, L. Armus +19
Mid-infrared diagnostics are presented for a large portion of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample plus archival data from the Infrared Space Observatory and…
Extended Mid-Infrared Aromatic Feature Emission in M 82
C. W. Engelbracht, P. Kundurthy, K. D. Gordon +19
We present new images (groundbased optical and mid-infrared (MIR) from the Spitzer Space Telescope) and spectra (from Spitzer) of the archetypal starburst galaxy M 82. The Spitzer…
Discovery of a 500 pc shell in the nucleus of Centaurus A
Alice C. Quillen, Joss Bland-Hawthorn, Mairi H. Brookes +5
Spitzer Space Telescope mid-infrared images of the radio galaxy Centaurus A reveal a shell-like, bipolar, structure 500 pc to the north and south of the nucleus. This shell is seen…
