Spatially Resolved Imaging at 350um of Cold Dust in Nearby Elliptical Galaxies
Lerothodi L. Leeuw, Jacqueline Davidson, C. Darren Dowell +1
Continuum observations at 350um are presented of seven nearby elliptical galaxies, for which CO-gas disks have recently been resolved with interferometry mapping. These SHARCII map…
The Dusty Disk of the Early Galaxy NGC 3656
Lerothodi L. Leeuw, Jacqueline Davidson, C. Darren Dowell +2
SHARC II, 350-micron continuum and archival HST J-H band maps are presented of NGC 3656, the brightest of our sample of six elliptical galaxies for which resolved CO gas disks have…
Warm Molecular Gas Traced with CO J=7->6 in the Galaxy's Central 2 Parsecs: Dynamical Heating of the Circumnuclear Disk
C. M. Bradford, G. J. Stacey, T. Nikola +4
We present an 11 arcsec resolution map of the central two parsecs of the Galaxy in the CO J =7->6 rotational transition. The CO emission shows rotation about Sgr A*, but also evide…
CO (J=7->6) Observations of NGC 253: Cosmic Ray Heated Warm Molecular Gas
C. M. Bradford, T. Nikola, G. J. Stacey +5
We report observations of the CO J=7->6 transition toward the starburst nucleus of NGC 253. This is the highest-excitation CO measurement in this source to date, and allows an esti…
SPIFI: a direct-detection imaging spectrometer for submillimeter wavelengths
C. M. Bradford, G. J. Stacey, M. R. Swain +6
The South Pole Imaging Fabry-Perot Interferometer (SPIFI) is the first instrument of its kind -- a direct-detection imaging spectrometer for astronomy in the submillimeter band. SP…
