The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by noon the previous Thursday so a meal can be provided.

The discovery of numerous relatively close planets orbiting low-mass stars signals a major planetary population that may be the primary environment explored in the search for life beyond the Solar System. The environments of these types of stars are...

The direct detection of gravitational waves in 2015, thanks to the LIGO and Virgo interferometers, opened a new window on our Universe. The discoveries during the first three observing runs already had an extraordinary impact on astrophysics...

Abstract: I will review a series of results regarding the extremal limit of generic black holes in both Einstein and Einstein-Maxwell theory. We will see that in AdS, at low temperatures, large tidal forces arise at the horizon. These tidal forces...

Abstract: Celebrating a hundred years of quantum mechanics, the United Nations has declared 2025 the International Year of Quantum Science and Technology. This is not only an occasion to step back and marvel at the progress, it also raises the...

Massive stars remain a centerpiece of astrophysical research, enriching their galactic environments throughout their dynamic lives and often-explosive ends, and leaving behind compact objects as remnants. The past decade has yielded great progress...

Observations by Magnetospheric Multiscale have demonstrated that magnetic reconnection occurs at Earth's bow shock, typically at thin current sheets arising from plasma instabilities and turbulence in the shock transition region. In this talk, we...
