This talk presents a simple, unified picture for the formation and evolution of star clusters. These objects are important in the structure and evolution of galaxies, primarily as the sites of star formation and stellar feedback. The talk is...

Bars are a key signpost in the evolutionary history of a disk galaxy. When a disk is sufficiently massive, dynamically cold and rotationally supported, and sufficient time has elapsed for the baryonic matter to exchange energy and angular momentum...

Large-scale magnetic fields exist in cosmic structures such as galaxies and galaxy clusters. Moreover, recent gamma ray observations have suggested the existence of magnetic fields even in void regions. In this talk I will explain how such large...

Stars are tidally disrupted by supermassive black holes when they are scattered onto low-pericenter orbits in distant galactic nuclei. Accretion of the bound debris results in a multiwavelength flare with bolometric luminosity comparable to or...

One of the final frontiers in modern cosmology is the formation of the first stars at the end of the cosmic dark ages, when the Universe transitioned from its simple initial state to one of ever increasing complexity. I will discuss how the first...

Galactic nuclei are the densest stellar environments in the Universe. The observed stellar distribution within the innermost 0.5 pc of the Milky Way exhibits spherical and counter-rotating disk structures. Existing theoretical models cannot...

The field of experimental quantum information started with the first realization of an entangling gate in 1995. Tools originally developed for precision spectroscopy, turned out extremely useful for generating Bell pairs and storing quantum...
