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...

The Nobel Prize in Physics for 2011 was awarded for the discovery that the expansion of the Universe is accelerating. Yet the physical origin of cosmic acceleration remains a mystery. The Dark Energy Survey (DES) aims to address the questions: why...

ABSTRACT: Galaxy formation involves a complex interplay of many nonlinear, poorly understood physical processes. This fact has limited progress in the field. Recent work has made significant steps forward by systematically surveying model parameter...
