Princeton University Thunch Talk

December 09, 2021 | 12:15pm - 1:15pm

I will present a review of how deep learning is used in astrophysics, and how this use is often misguided. I will introduce the term “scientific debt,” and argue that, though deep learning can quickly solve a complex problem, its success does not...

Institute for Advanced Study Astrophysics Seminar

December 09, 2021 | 11:00am - 12:00pm

In this talk, I will briefly discuss our work on understanding the 3D morphology of magnetic fields associated with molecular clouds. To study the 3D magnetic fields, we first proposed and demonstrated a new technique to determine the line-of-sight...

University of Pennsylvania Rittenhouse Lecture

December 08, 2021 | 3:30pm - 4:30pm

The 21 cm line of atomic hydrogen (HI) provides a powerful probe of the cool-to-warm interstellar gas in galaxies. Virtually all star-forming galaxies contain a cool neutral component of their interstellar medium representing the fuel reservoir from...

Princeton Center for Heliophysics Seminar

December 06, 2021 | 3:00pm - 4:00pm

A rich variety of wave phenomena exist in virtually every region of the geospace environment.  Understanding of the various wave signatures and driving mechanisms provided insight into the local conditions, not only at the instant that the waves are...

Princeton University Astroplasmas Seminar

December 03, 2021 | 12:30pm - 2:00pm

Pulsars produce coherent radio emission, the source of which has remained enigmatic. Recent computational work suggests this emission may be produced in nonstationary pair plasma discharges in the pulsar polar cap, where the pulsar electric field is...
