The AzTEC mm-Wavelength Camera
G. W. Wilson, J. E. Austermann, T. A. Perera +13
AzTEC is a mm-wavelength bolometric camera utilizing 144 silicon nitride micromesh detectors. Herein we describe the AzTEC instrument architecture and its use as an astronomical in…
First Surface-resolved Results with the IOTA Imaging Interferometer: Detection of Asymmetries in AGB stars
S. Ragland, W. A. Traub, J. -P. Berger +20
We have measured non-zero closure phases for about 29% of our sample of 56 nearby Asymptotic Giant Branch (AGB) stars, using the 3-telescope Infrared Optical Telescope Array (IOTA)…
First results with the IOTA3 imaging interferometer: The spectroscopic binaries lambda Vir and WR 140
J. D. Monnier, W. Traub, F. P. Schloerb +26
We report the first spatially-resolved observations of the spectroscopic binaries lambda Vir and WR 140, which includes the debut of aperture-synthesis imaging with the upgraded th…
