Journal ArticleDOI
Ultra-Compact HII Regions and Massive Star Formation
TL;DR: In this article, the authors discuss the evolution to the ultra-compact (UC) state, the properties of UC HII regions and their environments, and their use as probes of Galactic structure.
Journal ArticleDOI
MAGPIS: A Multi-Array Galactic Plane Imaging Survey
David J. Helfand,Robert H. Becker,Robert H. Becker,Richard L. White,Adam Fallon,Sarah Tuttle +5 more
TL;DR: MAGPIS as discussed by the authors is a multi-array survey of the first Galactic quadrant with an angular resolution, sensitivity and dynamic range that surpasses existing radio images of the Milky Way by more than an order of magnitude.

The earliest phases of high-mass star formation: a 3 square degree millimeter continuum mapping of Cygnus X
Frédérique Motte,Frédérique Motte,Sylvain Bontemps,Peter Schilke,Nicola Schneider,Karl M. Menten,D. Broguiere +6 more
TL;DR: In this article, the authors made an extensive 1.2 mm continuum mosaicing study of the Cygnus X molecular cloud complex using the MAMBO cameras at the IRAM 30 m telescope.
Journal ArticleDOI
The Proper Motion of Sagittarius A*. I. First VLBA Results
TL;DR: In this paper, the authors observed Sgr A* and two extragalactic radio sources nearby in angle with the VLBA over a period of 2 years and measured relative positions with an accuracy approaching 0.1 mas.
