The Warp and Spiral Arms of the Milky Way
E. S. Levine, Leo Blitz, Carl Heiles +1
We examine the outer Galactic HI disk for deviations from the b=0 plane by constructing maps of disk surface density, mean height, and thickness. We find that the Galactic warp is…
Thermal and non-thermal components of the interstellar medium at sub-kiloparsec scales in galaxies
R. Paladino, M. Murgia, T. T. Helfer +5
Aims: We present new radio continuum observations of ten BIMA SONG galaxies, taken at 1.4 GHz with the Very Large Array. These observations allow us to extend the study of the rela…
The Spiral Structure of the Outer Milky Way in Hydrogen
E. S. Levine, Leo Blitz, Carl Heiles
We produce a detailed map of the perturbed surface density of neutral hydrogen in the outer Milky Way disk demonstrating that the Galaxy is a non-axisymmetric multi-armed spiral. S…
The Role of Pressure in GMC Formation II: The H_2 - Pressure Relation
Leo Blitz, Erik Rosolowsky
We show that the ratio of molecular to atomic gas in galaxies is determined by hydrostatic pressure and that the relation between the two is nearly linear. The pressure relation is…
Giant Molecular Clouds in Local Group Galaxies
Leo Blitz, Yasuo Fukui, Akiko Kawamura +3
We present the first comparative study of extragalactic GMCs using complete data sets for entire galaxies and a uniform set of reduction and analysis techniques. We present results…
Molecular Gas in the Low Metallicity, Star Forming Dwarf IC 10
A. Leroy, A. D. Bolatto, F. Walter +1
We present a complete survey of CO 1->0 emission in the Local Group dwarf irregular IC 10. The survey, conducted with the BIMA interferometer, covers the stellar disk and a large f…
The Vertical Structure of the Outer Milky Way HI Disk
E. S. Levine, Leo Blitz, Carl Heiles
We examine the outer Galactic HI disk for deviations from the b=0 plane by constructing maps of disk surface density, mean height, and thickness. We find that the Galactic warp is…
A Magellanic Origin for the Warp of the Galaxy
Martin D. Weinberg, Leo Blitz
We show that a Magellanic Cloud origin for the warp of the Milky Way can explain most quantitative features of the outer HI layer recently identified by Levine, Blitz & Heiles (200…
