The proximity of our Galaxy's center presents a unique opportunity to study a galactic nucleus with orders of magnitude higher spatial resolution than can be brought to bear on any other galaxy. After more than a decade of diffraction-limited...

The meeting will be a hybrid presentation of in person, for Princeton University affiliates (net ID holders) and Invited Speakers, and a Zoom presentation for all NON PU affiliates.  Registration is required for everyone to receive the Zoom link and...

Learn about new developments in the study of supermassive black holes. Through the capture and analysis of twenty years of high-resolution imaging, the UCLA Galactic Center Group has moved the case for a supermassive black hole at the center of our...

Magnetic reconnection is ubiquitous in space and astrophysical plasmas rapidly converting magnetic field energy into plasma particles. Among numerous candidate kinetic mechanisms, ion acoustic instabilities driven by the relative drift between ions...

Abstract: The first quantum revolution brought us the great technological advances of the 20th century—the transistor, the laser, the atomic clock and GPS, the global positioning system.  We now realize that this 20th century hardware does not take...

Understanding galaxies and their evolution over time is critical for interpreting the stellar history and chemical enrichment of the Universe. Galaxies that lie at different distances help us fill in different pieces of the puzzle — from large...

The identity of dark matter remains a mystery, despite decades of theorizing and detection efforts. This includes the mechanism for its primordial production, its interactions with itself or with visible matter, and the very nature of dark matter...
