Structure and Kinematics of CO (J=2-1) Emission in the Central Region of NGC 4258
S. Sawada-Satoh, P. T. P. Ho, S. Muller +2
We present 12CO (J=2-1) observations towards the central region of the Seyfert 2 galaxy NGC 4258 with the Submillimeter Array (SMA). Our interferometric maps show two arm-like elon…
Compact Centimeter and Millimeter Sources in NGC 6334 I(N): OB Stars in the Making?
Luis F. Rodriguez, Luis A. Zapata, Paul T. P. Ho
We present sensitive, high angular resolution 1.3 cm and 7 mm observations of the massive core NGC 6334 I(N), a region known to be undergoing massive star formation. At 1.3 cm we d…
Discovery of Radio Emission from the Tight M8 Binary: LP 349-25
N. Phan-Bao, R. A. Osten, J. Lim +2
We present radio observations of 8 ultracool dwarfs with a narrow spectral type range (M8-M9.5) using the Very Large Array at 8.5 GHz. Only the tight M8 binary LP 349-25 was detect…
654 GHz Continuum and C18O (6-5) Observations of G240.31+0.07 with the Submillimeter Array
Huei-Ru Chen, Yu-Nung Su, Sheng-Yuan Liu +7
We report a dual-band observation at 223 and 654 GHz (460 micron) toward an ultracompact (UC) HII region, G240.31+0.07, with the Submillimeter Array. With a beam size of 1"5 X 0"8,…
Detection of CO Hotspots Associated with Young Clusters in the Southern Starburst Galaxy NGC 1365
Kazushi Sakamoto, Paul T. P. Ho, Rui-Qing Mao +2
We have used the Submillimeter Array for the first interferometric CO imaging toward the starburst-Seyfert nucleus of the southern barred spiral galaxy NGC 1365, which is one of th…
Subarcsecond-Resolution Radio Maps of Nearby Spiral Galaxies
Chao-Wei Tsai, Jean L. Turner, Sara C. Beck +4
We report subarcsecond-resolution VLA imaging of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, compact radio continuum sources are identif…
High Resolution Radio Maps of Four Nearby Spiral Galaxies
Chao-Wei Tsai, Jean L. Turner, Sara C. Beck +4
We report subarcsecond-resolution VLA imaging of the centers of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, 7 - 12 compact radio continu…
Silicon Monoxide Observations Reveal a Cluster of Hidden Compact Outflows in the OMC1 South Region
Luis A. Zapata, Paul T. P. Ho, Luis F. Rodriguez +3
We present high angular resolution () SiO J=54; line observations of the OMC1S region in the Orion Nebula made using the Submillimeter…
A Detection of [CII] line emission in the z=4.7 QSO BR1202-0725
D. Iono, M. S. Yun, M. Elvis +6
We present ~3'' resolution imaging of the z=4.7 QSO BR1202-0725 at 900 micron from the Submillimeter Array. The two submillimeter continuum components are clearly resolved from eac…
Hot Molecular Gas in the Nuclear Region of IC 342
Maria Montero-Castano, Robeson M. Herrnstein, Paul T. P. Ho
We present the first interferometric detection of extragalactic NH_3(6,6) emission in the nearby galaxy IC 342 made using the VLA. The data have a resolution of 7.8''x 5.0'' and tr…
Exploring High-Velocity NH_3(6,6) Emission at the Center of our Galaxy
Jennifer L. Donovan, Robeson M. Herrnstein, Paul T. P. Ho
Using the NH\3 (6,6) transition, which samples dense () molecular gas with an energy above ground of 412 K, we find hot gas at high velocities (--142 to --210 km s$^{-…
Possible Molecular Spiral Arms in the Protoplanetary Disk of AB Aur
Shin-Yi Lin, Nagayoshi Ohashi, Jeremy Lim +3
The circumstellar dust disk of the Herbig Ae star AB Aur has been found to exhibit complex spiral-like structures in the near-IR image obtained with the Subaru Telescope. We presen…
Imaging Molecular Gas in the Luminous Merger NGC 3256 : Detection of High-Velocity Gas and Twin Gas Peaks in the Double Nucleus
Kazushi Sakamoto, Paul T. P. Ho, Alison B. Peck
Molecular gas in the merging starburst galaxy NGC 3256 has been imaged with the Submillimeter Array at a resolution of 1'' x 2'' (170 x 340 pc at 35 Mpc). This is the first interfe…
Interferometric 890 micron Images of High Redshift Submillimeter Galaxies
