Thermal emission from magnetically aligned dust grains produces the observed mid-infrared polarization in the northern arm and east - west bar of SgrA West; recent arcsecond-resolution imaging polarimetry at 12.5 μm of these ionized filaments is pre

We present 8- to 13-μm spectra of the main-belt asteroids 1, 2, 6, 7, 10, 16, 45, 51, 56, 65, 78, and 451. None of these exhibit pronounced emission features, and all can be fitted reasonably well using a standard thermal model. We also present wide

We present 8-13 μm spectropolarimetry, and 12- and 2-μm imaging polarimetry of the southern massive star-forming region G333.6-0.2. Spectropolarimetry measurements show that the polarization observed towards the nebula contains a mixture of both ab

The spectral energy distributions are presented for 60 galaxies for which 8-13 μm, and in some cases 17-23 μm, spectra have been obtained. These IR bright galaxies are discussed in terms of their spectral properties in the mid-IR and the relationsh

We present imaging polarimetry of Sgr A at a wavelength of 12.5 μm, obtained with Michelle on UKIRT early in 2002. With considerably more sensitivity than previously available we have concentrated on the faint region bounded by the northern arm nort

We present linear spectropolarimetry in the wavelength range 4.5-4.8 μm of the embedded infrared source W33A. Our observations show for the first time the presence of polarization associated with the CO and XCN ice features, demonstrating that the a

We present observations of solid-state absorption features due to water ice, CO ice, and silicate dust in the spectrum of the bright infrared source (1RS 1) associated with the Herbig-Haro nebula HH 100 in the R Coronae Australis dark cloud. These ab

An array spectrometer was used on the nights of 1985 May 30–June 1 to observe the disks of Uranus and Neptune in the spectral regions 7–14 and 17–23 μm with effective resolution elements ranging from 0.23 to 0.87 μm. In the long-wavelength re
