SHARC-II 350 micron Observations of Thermal Emission from Warm Dust in z>=5 Quasars

Ran Wang, Jeff Wagg, Chris L. Carilli +10

We present observations of four z>= SDSS quasars at 350 micron with the SHARC-II bolometer camera on the Caltech Submillimeter Observatory. These are among the deepest observations…

A 1.3 cm wavelength radio flare from a deeply embedded source in the Orion BN/KL region

Jan Forbrich, Karl M. Menten, Mark J. Reid

Aims: Our aim was to measure and characterize the short-wavelength radio emission from young stellar objects (YSOs) in the Orion Nebula Cluster and the BN/KL star-forming region. M…

A multi-transition submillimeter water maser study of evolved stars - detection of a new line near 475 GHz

K. M. Menten, A. Lundgren, A. Belloche +2

Context: Maser emission from the H2O molecule probes the warm, inner circumstellar envelopes of oxygen-rich red giant and supergiant stars. Multi-maser transition studies can be us…

Formaldehyde Densitometry of Starburst Galaxies

Jeffrey G. Mangum, Jeremy Darling, Karl M. Menten +1

With a goal toward deriving the physical conditions in external galaxies, we present a survey of the formaldehyde emission in a sample of starburst systems. By extending a techniqu…

Millimeter wave spectral line surveys and line mapping studies of NGC6334I and I(N)

S. Thorwirth, A. J. Walsh, F. Wyrowski +8

NGC6334I and I(N) have been observed with the Swedish-ESO Submillimetre Telescope, SEST, at wavelengths of 3, 2, and 1.3 mm. Especially NGC6334 I shows rich emission from many diff…
