Astrophysics of galaxy clusters and groups with eROSITA
This thesis investigates non-gravitational astrophysical phenomena shaping the physical properties of galaxy clusters and groups. The impact of these processes is constrained by measuring the physical properties of galaxy clusters and groups using X-ray observations of eROSITA.openaire +1 more source
Detailed astrophysical properties of Lyman Break Galaxies
2003A large statistical sample of z~3 galaxies has been efficiently UV-color-selected, and confirmed spectroscopically. Here we present additional observations providing insight into the physical conditions in these Lyman Break Galaxies (LBGs), selected to be rapidly forming stars when the universe was ~15% of its current age.

Aspects of Cosmic-Ray Astrophysics in the Galaxy and Beyond
1996We review some salient aspects of cosmic-ray astrophysics. Recent advances are discussed, and several outstanding problems are sketched.

Astrophysics: Less greedy galaxies gulp gas
2010The cool molecular gas from which stars form has been detected in relatively ordinary faraway galaxies. The results point to a continuous fuelling of gas into the star-forming guts of assembling galaxies.
