Spatial Distribution of Warm Dust in Early-Type Galaxies
M. A. Pahre, M. L. N. Ashby, G. G. Fazio +1
Images taken with the IRAC instrument on the Spitzer Space Telescope show that the spatial distribution of warm dust emission in lenticular galaxies is often organized into dynamic…
The Off-nuclear Starbursts In NGC 4038/4039 (The Antennae Galaxies)
Z. Wang, G. G. Fazio, M. L. N. Ashby +7
Imaging of the Antennae galaxies (NGC 4038/4039) with the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope reveals large concentrations of star forming activity away…
The Infrared Array Camera (IRAC) for the Spitzer Space Telescope
G. G. Fazio, the IRAC team
The Infrared Array Camera (IRAC) is one of three focal plane instruments in the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images a…
Number Counts At 3 < lambda < 10 um From the Spitzer Space Telescope
G. G. Fazio, M. L. N. Ashby, P. Barmby +12
Infrared source counts at wavelengths 3 < lambda < 10 um cover more than 10 magnitudes in source brightness, four orders of magnitude in surface density, and reach an integrated su…
Mid-Infrared Galaxy Morphology Along the Hubble Sequence
M. A. Pahre, M. L. N. Ashby, G. G. Fazio +1
The mid-infrared emission from 18 nearby galaxies imaged with the IRAC instrument on Spitzer Space Telescope samples the spatial distributions of the reddening-free stellar photosp…
Probing the Early Stages of Low-Mass Star Formation in LDN 1689N: Dust and Water in IRAS 16293-2422A, B, and E
Ronald Stark, Goeran Sandell, Sara C. Beck +8
We present deep images of dust continuum emission at 450, 800, and 850 micron of the dark cloud LDN 1689N which harbors the low-mass young stellar objects (YSOs) IRAS 16293-2422A a…
