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 ...

Astronomical technical issues are discussed alongside early observations prior to 1980. Specific sources as well as the chemistry of the interstellar medium and early ideas on the Diffuse Interstellar ...

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 ...

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 ...

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 ...

Identification of the electronic spectrum of this fundamental diatomic cation; implications for a later astronomical search in the diffuse medium. Fulara, M Jakobi and J P Maier "Electronic ... This ...

The spaces between stars in our galaxy are enigmatic realms filled with vast, diffuse clouds of gas ... about the foundations of the cold interstellar medium," Josh Peek, an astronomer at the ...

The interstellar medium — matter and radiation in the space between stars — plays a key role in the Milky Way's material cycle and star formation. Zhang explained that most elements heavier ...
