Silicate absorption in heavily obscured galaxy nuclei
P. F. Roche, C. Packham, D. K. Aitken +1
Spectroscopy at 8-13 microns with T-ReCS on Gemini-S is presented for 3 galaxies with substantial silicate absorption features, NGC 3094, NGC 7172 and NGC 5506. In the galaxies wit…
Radio and infrared recombination studies of the southern massive star-forming region G333.6-0.2
Takuya Fujiyoshi, Craig H. Smith, James L. Caswell +4
We present high spatial resolution radio and near-infrared hydrogen recombination line observations of the southern massive star-forming region G333.6-0.2. The 3.4-cm continuum pea…
Mid-infrared, spatially-resolved spectroscopy of the nucleus of the Circinus galaxy
P. F. Roche, C. Packham, C. M. Telesco +5
High spatial resolution spectroscopy at 8-13microns with T-ReCS on Gemini-S has revealed striking variations in the mid-infrared emission and absorption in the nucleus of the Circi…
Circular Polarimetry and the Line of Sight to the BN Object
D. K. Aitken, J. H. Hough, A. Chrysostomou
The 3.1 micron absorption feature of water-ice has been observed spectroscopically in many molecular clouds and, when it has been observed spectropolarimetrically, usually a corre-…
The Magnetic Field Structure in W51A
A. Chrysostomou, D. K. Aitken, T. Jenness +4
We present 850 micron imaging polarimetry of the W51A massive star forming region performed with SCUBA on the JCMT. From the polarimetry we infer the column-averaged magnetic field…
The Galactic Disk Distribution of Planetary Nebulae With Warm Dust Emission Features: I
S. Casassus, P. F. Roche, D. K. Aitken +1
We investigate the galactic disk distribution of a sample of planetary nebulae characterised in terms of their mid-infrared spectral features. The total number of galactic disk PNe…
