Astrophysics Calendar

The calendar is a collection of events hosted by The Institute for Advanced Study, Princeton University, and other local institutions and groups focused on Astrophysics and Astronomy. Emails are sent out every Friday with the calendar for the upcoming week and daily emails are sent with each days events. If you are interested in being added to the calendar distribution list, please contact Amanda Cenker, Academic Assistant at IAS.

University of Pennsylvania Astrophysics Seminar

Ultralight sails for interstellar space travel
Deep Jariwala and Igor Bargatin
3:30pm|U.Penn, David Rittenhouse Laboratory, 4C6

We argue that light sails with nanometer-scale thicknesses that are rapidly accelerated to relativistic velocities by lasers must be significantly curved in order to reduce their intrafilm mechanical stresses and avoid tears. Using an integrated...

Institute for Advanced Study Astrophysics Seminar

Count your halos
11:00am|Bloomberg Lecture Hall

One of the strongest predictions of the standard cold dark matter paradigm is the hierarchy of structure down to Earth-mass scales.  However, individual self-bound clumps of dark matter--"halos"--are difficult to detect directly.  Instead, we use...

Princeton University Gravity Group Lunch Seminar

Gravity Group Introductions
12:00pm|Jadwin 102 (Joe Henry Room)

In order to participate, which we hope you will all be able to do, please either:
- upload your one slide to this folder in PDF format (or send your PDF to me by e-mail, if you prefer); or
- let me know by e-mail that you will be there but will...

Princeton University Astroplasmas Seminar

Shock acceleration in the inhomogeneous interstellar medium
12:30pm|Dome Room, Peyton Hall or Zoom

With the development of multi-messenger astronomy and the detection of astrophysical neutrinos, we are in a golden age of new cosmic ray (CR) measurements and studies. Supernova remnants are believed as the leading candidate for the source of...

Princeton University Gravity Initiative Fall Seminar Series

Spin Signatures in VLBI Images of Supermassive Black Hole Accretion Flows
Daniel Palumbo
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: The Event Horizon Telescope has released total intensity images of the Messier 87* and Sagittarius A* accretion flows; polarized images have been released for M 87*, and are imminent for Sgr A*. These images are a rich source of...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

Maps of the campus and of IAS housing can be found here: https://www.ias.edu/campus-resources/transportation. Parking Lot A is no longer available due to construction. The Auxiliary Lot is available.
Alex Schekochihin
10:30am|Wolfensohn Hall

Much of existing plasma (astro)physics is done hovering in the vicinity of a Maxwellian equilibrium, which is the maximum point of the standard Gibbs entropy and is achieved dynamically by means of two-particle collisions. In this seminar, I would...

Princeton University Gravity Initiative Special Seminar

Black Holes Are Watching You
Gautam Satishchandran
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition. This occurs because...
