The eSMA: description and first results (2008)

Bottinelli, Sandrine, Young, Ken H., Chamberlin, Richard, Tilanus, Remo P. J., Gurwell, Mark A., Wilner, Dave J., ...

The eSMA ("extended SMA") combines the SMA, JCMT and CSO into a single facility, providing enhanced sensitivity and spatial resolution owing to the increased collecting area at the longest baselines....

Low-Mass Star Forming Cores in the GF9 Filament (2008)

Furuya, Ray S., Kitamura, Yoshimi, Shinnaga, Hiroko

We carried out an unbiased mapping survey of dense molecular cloud cores traced by the NH3 (1,1) and (2,2) inversion lines in the GF9 filament which contains an extremely young low-mass protostar...

Submillimeter Observations of The Isolated Massive Dense Clump IRAS 20126+4104 (2008)

Shinnaga, Hiroko, Phillips, Thomas G., Furuya, Ray S., Cesaroni, Riccardo

We used the CSO 10.4 meter telescope to image the 350 micron and 450 micron continuum and CO J=6-5 line emission of the IRAS 20126+4104 clump. The continuum and line observations show that the clump...

SMA Imaging of the Maser Emission from the H30$\alpha$ Radio Recombination Line in MWC349A (2008)

Weintroub, Jonathan, Moran, James M., Wilner, David J., Young, Ken H., Rao, Ramprasad, Shinnaga, Hiroko

We used the Submillimeter Array to map the angular distribution of the H30$\alpha$ recombination line (231.9 GHz) in the circumstellar region of the peculiar star MWC349A. The resolution was...

A SEARCH FOR INTERSTELLAR H$_2$DO$^+$ (2008)

Morong, Christopher P., Saito, Shuji, Furuya, Takashi, Shinnaga, Hiroko, Oka, Takeshi

T. Furuya, S. Saito, & M. Araki, J. Chem. Phys. 127, 244314 (2007)T. Araki & S. Saito, J. Chem. Phys. 128, 034311 (2008)

The Initial Conditions for Gravitational Collapse of a Core: An Extremely Young Low-Mass Class 0 Protostar GF9-2 (2006)

Furuya, Ray S., Kitamura, Yoshimi, Shinnaga, Hiroko

We present a study of the natal core harboring the class 0 protostar GF9-2 in the filamentary dark cloud GF 9 (d = 200 pc). GF9-2 stands unique in the sense that it shows H2O maser emission, a clear...

Interferometric Observation of the Highly Polarized SiO Maser Emission from the $v=1, J=5-4$ Transition Associated with VY Canis Majoris (2004)

Shinnaga, Hiroko, Moran, James M., Young, Ken H., Ho, Paul T. P.

We used the Submillimeter Array to image the SiO maser emission in the $v=1$, \$J=5-4$ transition associated with the peculiar red supergiant VY Canis Majoris. We identified seven maser components...

High velocity bipolar outflow and disk-like envelope in the carbon star V Hya (2004)

Hirano, Naomi, Shinnaga, Hiroko, Fong, David, Keto, Eric, Patel, Nimesh, ...

Using the partially completed Submillimeter Array with five antennas, we have observed the CO J=2-1 and 3-2 emission from the envelope surrounding the carbon star V Hya. The high-angular resolution...
