Star Formation and the ISM in Four Dwarf Irregular Galaxies
L. M. Young, L. van Zee, K. Y. Lo +2
We present new, high sensitivity VLA observations of HI in four dwarf galaxies (UGCA 292, GR8, DDO 210, and DDO 216) and we use these data to study interactions between star format…
Distorted HI Gas in the Widely Separated LIRG Arp 256
Jacqueline Chen, K. Y. Lo, Robert A. Gruendl +2
We present new interferometric HI and CO (1-0) observations of the luminous infrared source, Arp 256. Arp 256 consists of two spiral galaxies in an early stage of merging, with a p…
Nature of widely separated ultraluminous infrared galaxies
Dinh-V-Trung, K. Y. Lo, D. -C. Kim +2
In the complete sample of ultraluminous infrared galaxies (ULIRGs) compiled by Kim (1995) about 5% consists of widely separated galaxies which are presumably in the early phase of…
Molecular Gas and the Modest Star Formation Efficiency in the ``Antennae'' Galaxies: Arp~244=NGC 4038/39
Yu Gao, K. Y. Lo, S. -W. Lee +1
(abridged) We report here a factor of 5.7 higher total CO flux in Arp~244 (the ``Antennae'' galaxies) than that previously accepted in the literature (thus a total molecular gas ma…
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…
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…
