The New Milky Way

Science, 1983
Our understanding of the large-scale structure of the Milky Way has undergone considerable revision during the past few years. The Galaxy is larger and much more massive than was previously supposed; the newly discovered mass consists of nonluminous matter which is likely to be the dominant form of matter in the universe.

The Milky Way, Transformed

Scientific American, 2016
The article focuses on the development of a map of the Milky Way galaxy from the European Space Agency's Gaia spacecraft. It states the dataset provides a preliminary position of one billion stars and the sideways motions and distances of the brightest two million stars in the sky.

Giant Bubbles of the Milky Way

Scientific American, 2014
The article discusses the discovery of Fermi bubbles that extend over the center of the Milky Way galaxy in lobes as of 2014, mentioning theories from astronomers which involve the potential relationship of the bubbles to supernovae or a black hole. Topics include the Fermi Gamma-ray Space Telescope, the work of the astronomer Douglas Finkbeiner, dark ...

The Evolution of the Milky way

Astrophysics and Space Science, 1999
A two-dimensional chemodynamical model of the Milky Way Galaxy is presented that can account for the structural, kinematical, and chemical pecularities of the galactic components in a self-consistent way. The dynamics of three stellar components and the multi-phase interstellar medium consisting of clouds and intercloud gas are followed in detail. Mass

The Mass of the Milky Way

2006
The Mass distribution of the Galaxy is reasonably well understood. Out to a radius of at least 200kpc, the enclosed mass increases roughly linearly with radius at about 10(10)M(circle dot) per kpc. The inner mass distribution is inconsistent with what we know to be present in stars and gas.
