Abstract: The theory of General Relativity has successfully passed a large number of observational tests. The theory has been extensively tested in the weak-field regime with experiments in the Solar System and observations of binary pulsars. The...

Data from ESA’s Gaia mission is already revolutionizing Galactic astronomy, providing an unprecedented view of the Solar neighborhood and beyond. However, while it provides us a great opportunity to transform our understanding of the Milky Way, it...

Alfvén waves, a fundamental mode of magnetized plasmas, are ubiquitous throughout our heliosphere. The non-linear behavior of these modes may play key roles in the physics of the turbulent solar wind, heating of the solar corona, and the behavior of...

The Bahcall Lunch follows the astrophysics colloquium lecture. 

The study of the transient night sky offers an opportunity to tackle some long-standing open questions in astrophysics, such as: how and why do stars explode? when do such explosions leave behind neutrons stars or black holes? and what is the origin...
