The TopHat collaboration flew the TopHat experiment to map the
Southern Celestial Cap in January 2001. This unique payload,launched
from McMurdo Station in Antarctica, is mounted on the top of a balloon
in order to provide a large-area map with highly redundant sky
sampling. We have produced a 5-band, far-infrared 57 deg diameter sky
map centered on the Southern celestial pole and we are currently
working with this map to extract unique information on the
far-infrared emission of galactic dust.
To date we have produced one scientific publication on the integrated
emission of dust in the Small and Large Magellanic clouds (Aguirre 2003) and
we are currently working at UMass on combining the TopHat, COBE/DIRBE,
and WMAP maps in order to derive dust masses, dust temperatures, and
gas/dust ratios for regions in and out of the galactic plane. The
resulting spectra span over two orders of magnitude in frequency and
over four orders of magnitude in flux - providing a comprehensive view
of integrated mm and submm-wave emission in and out of our galactic
plane.
