TLDR
The entire sky has now been surveyed in the 21 cm line with an angular resolution of about 05 degree as discussed by the authors, and the sky outside the galactic plane has been almost completely sampled.Abstract:
The entire sky has now been surveyed in the 21-cm line with an angular resolution of about 05 degree In the north, above declination-20° or so, the “galactic plane” |b|<10° has been completely sampled Weaver and Williams (1973; 1974) Above declination -30° or so, the sky outside the galactic plane has been almost completely sampled (Heiles and Habing, 1974; Heiles, 1975)read more

The interstellar environment of our galaxy
TL;DR: In this article, the authors present the current knowledge and understanding of the interstellar medium of our galaxy and discuss the interaction of these interstellar constituents, both with each other and with stars, in the framework of the general galactic ecosystem.

TL;DR: In this paper, Parkes telescope observations of neutral hydrogen (Hi) in the Small Magellanic Cloud (SMC) were combined with an Australia Telescope Compact Array (ATCA) aperture synthesis mosaic to obtain a set of images sensitive to all angular (spatial) scales between 98 arcsec (30 pc) and 4° (4 kpc).

High-Velocity Clouds: Building Blocks of the Local Group
TL;DR: In this paper, a reexamination of the Local Group hypothesis for the high-velocity clouds (HVCs) connects their properties to the hierarchical structure formation scenario and to the gas seen in absorption toward quasars.
Journal ArticleDOI
The Hi Distribution of the Milky Way
TL;DR: In this paper, the authors used the 21-cm emission line of neutral atomic hydrogen (Hi) gas to study the structure and dynamics of the Milky Way galaxy and found that the Hi gas traces a dynamical Galactic ISM with structures on all scales, from tens of astronomical units to kiloparsecs.
Journal ArticleDOI
3D mapping of the dense interstellar gas around the Local Bubble
TL;DR: In this article, the authors present 3D absorption maps of the local distribution of neutral gas towards 1005 sight-lines with Hipparcos distances as viewed from a variety of different galactic projections.

The Magellanic Stream.
TL;DR: The Magellanic Stream as discussed by the authors is a long filament of H i that follows a great circle over its entire 180° length and connects with the long Hi filament discovered by Wannier and Wrixon (1972) and van Kuilenburg (1972).
Journal ArticleDOI
The Interstellar Magnetic Field
TL;DR: In this article, the effects of the magnetic field on the polarization of radiation on the local field, the galactic scale, the field in clouds and the fields in very dense clouds are reviewed.

Stellar winds, supernovae, and the origin of the H I supershells
TL;DR: In this paper, it was shown that the H I shells and supershells are a natural byproduct of the interaction of the stellar winds and supernovae, originating from stars in typical OB associations, with the surrounding interstellar medium.

An almost complete survey of 21-centimeter line radiation for galactic latitudes of at least 10 deg. VI - Energetic expanding H I shells
TL;DR: In this paper, it was shown that much of the interstellar volume is probably contained with H I shells, and that the diameters change with velocity in the manner expected for expanding shells.
