Astrophysics

In this talk I will review the current state of and future prospects for exoplanet demographics. I will walk through the latest understanding of the frequency of Earth-like planets from Kepler, and their implications for NASA’s next flagship mission...

This talk will provide an overview of recent progress in understanding heating of the inner heliosphere via turbulent dissipation. NASA's Parker Solar Probe (PSP) mission, launched in 2018, has comprehensive in situ instrumentation that has enabled...

The Bahcall Lunch follows the astrophysics colloquium lecture. Registration is required by 4pm the previous Thursday so a meal can be provided. Email Amanda at cenker@ias.edu with questions.

Stellar streams form as dwarf galaxies and globular clusters tidally disrupt around their host galaxy. To date, more than 100 streams have been detected around our Galaxy. In this talk, I will begin with an overview of how streams form, how they can...

While recent observations of young protostellar disks have revealed much about their structure, the formation process from molecular cloud cores and subsequent evolution remains relatively poorly understood, with the role of the magnetic field in...

Abstract: We will start with a review of previous results concerning  instabilities of rotating Kerr black holes to massive scalar field perturbations. These instabilities are connected to superradiance and hence do not occur on the Schwarzschild...

Claims of a low clustering amplitude (S_8) at low redshifts from weak galaxy lensing measurements trace back nearly a decade, however, recent work suggests these results may be driven by large baryonic feedback or mischaracterization of linear...

In a protoplanetary disk, a sufficiently massive planet can excite a pressure bump, which in turn become a preferred location for the formation of a new planet core. This creates a feedback loop that quickly assembles multiple planet cores, and this...
