The Embedded Super-Star Cluster of SBS 0335-052
Sauvage, Marc; Plante, Stéphanie
We analyze the infrared (6-100 µm) spectral energy distribution of the blue compact dwarf and metal-poor (Z=Zsolar/41) galaxy SBS 0335-052. With the help of DUSTY, a program that solves the radiation transfer equations in a spherical environment, we evaluate that the infrared emission of SBS 0335-052 is produced by an embedded sup…
The Infrared Space Observatory Deep Asteroid Search
Tedesco, Edward F.; Desert, François-Xavier
A total of six deep exposures (using the astronomical observation template CAM01 with a 6" pixel field of view) through the ISOCAM LW10 filter (IRAS band 1, i.e., 12 µm) were obtained on a ~15' square field centered on the ecliptic plane. Point sources were extracted using the technique described in 1999 by Désert et al. Two known asteroids …
ISO LWS Observations of the Two Nearby Spiral Galaxies NGC 6946 and NGC 1313
Dale, Daniel A.; Rubio, Monica; Rubin, Robert H. +8 more
We present the analysis of Infrared Space Observatory long-wavelength spectrometer (LWS) observations of the two nearby late-type galaxies NGC 1313 and NGC 6946. Both galaxies have been fully mapped in the [C II] far-infrared fine-structure line at 158 µm, and some regions have been observed also in the [O I] 63 µm and [N II] 122 &micr…
An Infrared Space Observatory Atlas of Bright Spiral Galaxies
Bendo, George J.; Leech, Kieron; Metcalfe, Leo +11 more
In this first paper in a series we present an atlas of infrared images and photometry from 1.2 to 180 µm for a sample of bright spiral galaxies. The atlas galaxies are an optically selected, magnitude-limited sample of 77 spiral and S0 galaxies chosen from the Revised Shapley-Ames Catalog (RSA). The sample is a representative sample of spira…
Multiwavelength Study of the Nebula Associated with the Galactic LBV Candidate HD 168625
Nota, A.; Smith, L. J.; Clampin, M. +3 more
We present high-resolution HST imaging of the nebula associated with the Galactic luminous blue variable candidate HD 168625, together with ISO imaging and Anglo-Australian Telescope echelle spectroscopy. The overall nebular morphology is elliptical, with the major axis at P.A.~=120°. The dimensions of the nebula are 12"×16.7" at Hα and 15.5"×23.5…
Star Formation in the Infrared Space Observatory Atlas of Bright Spiral Galaxies
Bendo, George J.; Leech, Kieron; Metcalfe, Leo +11 more
We investigate star formation along the Hubble sequence using the Infrared Space Observatory Atlas of Bright Spiral Galaxies. Using mid-infrared and far-infrared flux densities normalized by K-band flux densities as indicators of recent star formation, we find several trends. First, star formation activity is stronger in late-type (Sc-Scd) spirals…
Far-Infrared Spectroscopy of the HH 1/2 Outflow
Molinari, Sergio; Noriega-Crespo, Alberto
The HH 1/2 system has been observed with the two spectrometers on board the Infrared Space Observatory. Diffuse [C II] 158 µm emission indicates the presence of a photodissociation region (PDR), which is only in part due to the external far-UV (FUV) irradiation from the nearby Orion Nebula. Additional irradiation must originate locally, and …
Observations of Galaxies with the Midcourse Space Experiment
Carey, Sean J.; Kraemer, Kathleen E.; Price, Stephan D. +1 more
We have imaged eight nearby spiral galaxies with the SPIRIT III infrared telescope on the Midcourse Space Experiment (MSX) satellite in the mid-infrared at 18" resolution at 8.3, 12.1, 14.7, and 21.3 µm. Each of the eight shows interesting structure not previously detected with older, lower resolution infrared data sets, such as a resolved n…
Infrared Space Observatory Polarimetric Imaging of the Egg Nebula (RAFGL 2688)
Kastner, Joel H.; Siebenmorgen, Ralf; Li, Jingqiang +1 more
We present polarimetric imaging of the protoplanetary nebula RAFGL 2688 obtained at 4.5 µm with the Infrared Space Observatory (ISO). We have deconvolved the images to remove the signature of the point spread function of the ISO telescope, to the extent possible. The deconvolved 4.5 µm image and polarimetric map reveal a bright point s…
