The Physics of Galaxy Accretion
How do galaxies get the gas needed to fuel star formation?' remains a fundamental open question, even for the Milky-Way. I will review recent theoretical developments in galaxy accretion physics, which go beyond the classic separation between 'cold' and 'hot' accretion. I will also discuss the potential implications of different accretion modes for theStern, Jonathan +8 more

Large spectroscopic and astrometric surveys, such as APOGEE and Gaia, provide us with large multi-dimensional data sets that allow us to study the Milky Way and its system of satellite dwarf galaxies in unprecedented detail. Among their many applications, these new tools afford us potent means by which to look for evidence of the accretion of dwarf ...

Black Hole Accretion in Primordial Galaxies
2020Supermassive black holes (SMBHs) with masses up to 1010M⊙ are thought to power the emission from quasars and Active Galactic Nuclei. Surprisingly, these extremely massive, compact objects are already in place within the first billion years from the Big Bang, or redshift z ≥ 6.

Modelling accreting white dwarf populations in galaxies
2016Diese Arbeit beschäftigt sich mit der Modellierung von Binärsystemen akkretierender weißer Zwerge in Galaxien. Wir verwenden einen hybriden Binärpopulation-Synthese Ansatz um die Entstehung und Entwicklung von akkretierenden weißen Zwergen zu untersuchen.
