A size of ~1 AU for the radio source Sgr A* at the centre of the Milky Way
Zhi-Qiang Shen, K. Y. Lo, M. -C. Liang +2
Although it is widely accepted that most galaxies have supermassive black holes (SMBHs) at their centers^{1-3}, concrete proof has proved elusive. Sagittarius A* (Sgr A*)^4, an ext…
The Irradiation Origin of Beryllium Radioisotopes and Other Short-lived Radionuclides
Matthieu Gounelle, Frank H. Shu, Hsien Shang +3
Two explanations exist for the short-lived radionuclides present in the solar system when the CAIs first formed. They originated either from the ejecta of a supernova or by the in…
Submillimeter emission from the hot molecular jet HH 211
A. Palau, P. T. P. Ho, Q. Zhang +7
We observed the HH 211 jet in the submillimeter continuum and the CO(3-2) and SiO(8-7) transitions with the Submillimeter Array. The continuum source detected at the center of the…
SiO J=5--4 in the HH211 Protostellar Jet Imaged with the SMA
Naomi Hirano, Sheng-Yuan Liu, Hsien Shang +5
We have mapped the SiO J=5-4 line at 217GHz from the HH211 molecular outflow with the Submillimeter Array (SMA). The high resolution map (1.6''x0.9'') shows that the SiO J=5-4 emis…
CO J=6-5 observations of TW Hya with the SMA
C. Qi, D. J. Wilner, N. Calvet +5
We present the first images of the 691.473 GHz CO J=6-5 line in a protoplanetary disk, obtained along with the 690 GHz dust continuum, toward the classical T Tauri star TW Hya usin…
A two-dimensional electrodynamical outer gap model for gamma-ray pulsars: Gamma-ray spectrum
J. Takata, S. Shibata, K. Hirotani +1
A two-dimensional electrodynamical model is used to study particle acceleration in the outer magnetosphere of a pulsar. The charge depletion from the Goldreich-Julian charge densit…
Interferometric Measurements of Variable 340 GHz Linear Polarization in Sagittarius A*
D. P. Marrone, J. M. Moran, J. -H. Zhao +1
Using the Submillimeter Array, we have made the first high angular resolution measurements of the linear polarization of Sagittarius A* at submillimeter wavelengths, and the first…
Discovery of a nearby M9 dwarf
N. Phan-Bao, M. S. Bessell, E. L. Martin +8
We report the discovery of a new M9.0 dwarf at only 8.2 pc, which we identified in our search for nearby ultracool dwarf (I-J >= 3.0, later than M8.0) in the DENIS database. We mea…
A High-Mass Protobinary System in the Hot Core W3(H2O)
Huei-Ru Chen, William J. Welch, David J. Wilner +1
We have observed a high-mass protobinary system in the hot core W3(H2O) with the BIMA Array. Our continuum maps at wavelengths of 1.4mm and 2.8mm both achieve sub-arcsecond angular…
Infall and Outflow around the HH 212 protostellar system
Chin-Fei Lee, Paul T. P. Ho, Henrik Beuther +4
HH 212 is a highly collimated jet discovered in H2 powered by a young Class 0 source, IRAS 05413-0104, in the L1630 cloud of Orion. We have mapped around it in 1.33 mm continuum, 1…
In Search of Circumstellar Disks Around Young Massive Stars
Luis Zapata, Luis Rodriguez, Paul Ho +2
We present 7 mm, 1.3 cm and 3.6 cm continuum observations made with the Very Large Array toward a sample of ten luminous IRAS sources that are believed to be regions of massive sta…
Virial masses and the baryon fraction in galaxies
H. Hoekstra, B. C. Hsieh, H. K. C. Yee +2
We have measured the weak lensing signal as a function of restframe luminosity for a sample of `isolated' galaxies. These results are based on four-band photometry from the Red-Seq…
NGC 7679: an anomalous, composite Seyfert 1 galaxy whose, X-ray luminous AGN vanishes at optical wavelengths
L. M. Buson, M. Cappellari, E. M. Corsini +3
Morphological disturbances and gas kinematics of the SB0 galaxy NGC 7679=Arp 216 are investigated to get clues to the history of this highly composite object, where AGN and starbur…
Widely separated binary systems of very low mass stars
N. Phan-Bao, E. L. Martin, C. Reyle +2
In this paper we review some recent detections of wide binary brown dwarf systems and discuss them in the context of the multiplicity properties of very low-mass stars and brown dw…
Submillimeter Array 440m/690GHz line and continuum observations of Orion-KL
H. Beuther, Q. Zhang, M. J. Reid +9
Submillimeter Array observations of Orion-KL at 1'' resolution in the 440mu/690GHz band reveal new insights about the continuum and line emission of the region. The 440mu continuum…
A disk of dust and molecular gas around a high-mass protostar
Nimesh A. Patel, Salvador Curiel, T. K. Sridharan +7
The processes leading to the birth of low-mass stars such as our Sun have been well studied, but the formation of high-mass (> 8 x Sun's mass) stars has heretofore remained poorly…

Kazushi Sakamoto, Paul T. P. Ho, Daisuke Iono +7
The central 2x1 kpc of the starburst galaxy NGC 253 has been imaged using the Submillimeter Array at a 60 pc resolution in the J=2-1 transitions of 12CO, 13CO, and C18O as well as…
