- 8 December 1994
Physics
A map of atomic hydrogen in the nearest interacting group of galaxies (that dominated by M81), obtained by combining 12 separate fields observed with the Very Large Array, which should have detected all H I complexes more massive than 106 solar masses.
The Neutral Interstellar Medium in Nearby Dwarf Galaxies. III. Sagittarius DIG, LGS 3, and Phoenix
- L. M. YoungK. Lo
- 1 December 1997
Physics
We present new VLA observations of the H I medium of the Local Group dwarf galaxies Sag DIG, LGS 3, and Phoenix. Sag DIG is a gas-rich, blue dwarf irregular with some known recent star formation,…

The Neutral Interstellar Medium in Nearby Dwarf Galaxies. II. NGC 185, NGC 205, and NGC 147
- L. M. YoungK. Lo
- 10 February 1997
Physics
We present new, high-resolution observations of the interstellar medium (ISM) in the two dwarf elliptical galaxies NGC 185 and NGC 205, as well as a new upper limit on the H I content of the dwarf…

▪ Abstract In the Galaxy, microwave radiation can be amplified in the interstellar medium in the immediate neighborhood of young stellar objects, or circumstellar envelopes around evolved stars,…
Water Maser Emission and the Parsec-Scale Jet in NGC 3079
- A. TrotterL. GreenhillJ. MoranM. ReidJ. IrwinK. Lo
- 5 December 1997
Physics
We have conducted VLBI observations at subparsec resolution of water maser and radio continuum emission in the nucleus of the nearby active galaxy NGC 3079. The 22 GHz maser emission arises in…
H I streamers around M82 - Tidally disrupted outer gas disk
Our new VLA observations of M82 reveals a triangular central concentration of neutral atomic gas (1.9×10 8 M ○. ) and several ≥10 kpc long tidal streamers originating from M82 itself. The coincidence…
