We can probe the ionized interstellar medium through imaging and timing observations of compact radio sources. As the radio waves pass through the interstellar medium, they are distorted and delayed ...

Specific sources as well as the chemistry of the interstellar medium and early ideas on the Diffuse Interstellar Bands DIBs prior to the discovery of C60 are also discussed. The Algonquin Park ...

The main theme of my research continues to be observational studies of the chemistry and physics of the diffuse and translucent interstellar medium. This includes analysis of the interaction between ...

Research in the group of Norbert Przybilla focusses on the quantitative spectroscopy of the main constituents of galaxies: the stars and the interstellar medium. It encompasses observation, model ...

ABSTRACT The 2175 Å absorption bump, a feature often ascribed to graphite grains and ubiquitous in the spectra of sight lines through the Galactic diffuse interstellar medium, is generally weak or ...

This bubble is a rarified region of interstellar space, much less dense than the surrounding medium. Moreover ... The geocorona, a diffuse halo of hydrogen gas extending far beyond Earth ...
