Dusty waves on a starry sea : The mid-infrared view of M31
Mid-infrared observations of the Andromeda galaxy, M31, obtained with the Infrared Array Camera on board the Spitzer Space Telescope are presented. The image mosaics cover areas of approximately 37 ×Expand
Silicate Mineralogy of the Dust in the Inner Coma of Comet C/1995 01 (Hale-Bopp) Pre- and Postperihelion
We present 7.5-13.4 μm infrared (IR) spectrophotometry (R180-360) of the 10 μm silicate emission from dust in the inner coma (i.e., within a diameter of 3'') of comet C/1995 O1 (Hale-Bopp) at fourExpand
SPITZER SPACE TELESCOPE INFRARED IMAGING AND SPECTROSCOPY OF THE CRAB NEBULA
We present 3.6, 4.5, 5.8, 8.0, 24, and 70 μm images of the Crab Nebula obtained with the Spitzer Space Telescope IRAC and MIPS cameras, low- and high-resolution Spitzer IRS spectra of selectedExpand
Rectified Asteroid Albedos and Diameters from IRAS and MSX Photometry Catalogs
Rectified diameters and albedo estimates of 1517 main-belt asteroids selected from IRAS and the Mid-Course Space Experiment asteroid photometry catalogs are derived from updated infrared thermalExpand
GRAIN PROPERTIES OF COMET C/1995 O1 (HALE-BOPP)
We present the analysis of 7.6-13.2 μm infrared (IR) spectrophotometry (R 250) of comet C/1995 O1 (Hale-Bopp), in conjunction with concurrent observations that extend the wavelength coverage of theExpand
A Spitzer IRAC Census of the Asymptotic Giant Branch Populations in Local Group Dwarfs. I. WLM
We present Spitzer IRAC observations at 3.6 and 4.5 ?m along with optical data from the Local Group Galaxies Survey to investigate the evolved stellar population of the Local Group dwarf irregularExpand
Stellar Populations and Mass Loss in M15: A Spitzer Space Telescope Detection of Dust in the Intracluster Medium
We present Spitzer Space Telescope IRAC and MIPS observations of the Galactic globular cluster M15 (NGC 7078), one of the most metal-poor clusters, with a [Fe/H] = -2.4. Our Spitzer images reveal aExpand
First spectroscopic measurements of [O III] emission from Lyα selected field galaxies at z ∼ 3.1
We present the first spectroscopic measurements of the [O III] 5007 A line in two z ~ 3.1 Lyα emitting galaxies (LAEs) using the new near-infrared instrument LUCIFER1 on the 8.4 m Large BinocularExpand
Variations in the 3 micron spectrum across the Orion Bar: polycyclic aromatic hydrocarbons and related molecules.
TLDR
Long-slit spectra across the Orion Bar reveal significant differences in the spatial behavior of the components of the 3 microns polycyclic aromatic hydrocarbon (PAH) spectrum, which could produce the complicated spectral and spatial structure at 3.40 microns. Expand
