Title: | The spatial extent of gas and dust in galaxy nuclei |
PI: | Patrick Roche |
Co-I(s): | David Aitken |
Abstract
We propose to use TReCs to measure the spatial extent of the dust emission and ionic line emission in a sample of nearby infrared bright galaxy nuclei with prominent silicate absorption bands. The increased opacity at the peak of the silicate feature means that in a centrally heated cloud, the emission near 9.7 microns will arise preferentially from the outer regions. Measurement of the spatial structure in the galaxy nuclei will enable us to place some limits on the temperature structure of the mid-IR emitting dust. Measurement of ionic emission lines (especially [SIV]) will reveal whether the high excitation gas is coincident with the dusty core.
