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
Evolution of Astrophysics: Stars, Galaxies, Dark Matter, and Particle Acceleration
2012Starting about a hundred years ago we review some of the most exciting astrophysics science developments in Stars, Galaxies, Dark Matter, and Particle Acceleration, (i) the discovery of Gamma-ray Bursts, probably the explosion of a special subclass of very massive stars that then produce a black hole; (ii) the class of supernova explosions, called type

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.

Astrophysical Jets: Optical Morphologies of Radio Jets and their Parent Galaxies
1983We discuss the relevance of optical observations for a better understanding of the nature of cosmic jets and of the phenomena related to them. We insist in particular on the morphology of the optical jets known as yet, especially that of M87, from high-resolution observations. We also discuss the new insights that the detection of interstellar dust can

Astrophysical implications of the fermionic dark matter in galaxies
2017The main aim of this thesis is to use a fermionic dark matter (DM) model (the Ruffini-Arg\"uelles-Rueda (RAR) model) to describe the distribution of dark matter in galactic halos as an astrophysical probe of the fermionic nature of dark matter. My thesis work focuses then on testing possible effects that are caused by DM (and modeled by the RAR model ...
