Mid-Infrared Images of Luminous Infrared Galaxies in a Merging Sequence

Chorng-Yuan Hwang, K. Y. Lo, Yu Gao +2

We report mid-infrared observations of several luminous infrared galaxies (LIGs) carried out with the Infrared Space Observatory. Our sample was chosen to represent different phase…

Luminous IR Galaxies in a Merger Sequence: BIMA CO Imaging

Yu Gao, R. A. Gruendl, C. -Y. Hwang +1

In order to trace observationally the conditions in the interstellar medium (ISM) that lead to starbursts, we have used the newly expanded Berkeley-Illinois-Maryland Association (B…

Intrinsic Size and Shape of Sgr A*: 3.6 AU by <1 AU

K. Y. Lo, Z. -Q. Shen, J. -H. Zhao +1

By means of near-simultaneous multi-wavelength VLBA measurements, we determine for the first time the intrinsic size of Sgr A* to be 3.6 AU by <1 AU with the major axis oriented es…

Intrinsic Size OF Sgr A*: 72 Schwarzschild Radii

K. Y. Lo, Z. -Q. Shen, J. -H. Zhao +1

Recent proper motion studies of stars at the very center of the Galaxy strongly suggest that Sagittarius (Sgr) A*, the compact nonthermal radio source at the Galactic Center, is a…
