WitrynaAbstract. We map out calcium ii and sodium i absorption (Fraunhofer H, K & D lines) induced by both the interstellar medium and the circumgalactic medium of the Milky Way. Our measurements cover more than 9000 deg 2 and make use of about 300 000 extragalactic spectra from the Sloan Digital Sky Survey. We present absorption maps … In astronomy, the interstellar medium (ISM) is the matter and radiation that exist in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space. … Zobacz więcej Table 1 shows a breakdown of the properties of the components of the ISM of the Milky Way.
