Princeton University Star Formation/ISM Rendezvous (SFIR)

Feeding a Protostar with 10,500 au Scale Streamers
Jaime Pineda
11:00am|Virtual Meeting

Dense cores are the places where stars are formed within the supersonic Molecular Clouds. These dense regions (n~10^5 cc) are cold (T~10 K) and display subsonic levels of turbulence (Mach ~ 0.5), and represent the initial conditions for both star...

University of Pennsylvania Astronomy Seminar

How to Find an Earth
Megan Bedell
2:00pm|Virtual Event

The detection of an Earth twin (an Earth-mass planet orbiting a Sun-like star within the habitable zone) has recently become feasible for the first time thanks to advances in observational technology. The Terra Hunting Experiment is a 10-year...

Geometric and Modular Representation Theory Seminar

Microlocal sheaves on certain affine Springer fibers
3:00pm|Simonyi Hall 101 and Remote Access

For homogeneous affine Springer fibers (those with $G_m$ symmetry), we realize them as Lagrangian cycles inside ambient symplectic varieties, and make sense of microlocal sheaves supported on these affine Springer fibers. We also propose a...

Rutgers University Physics/Astronomy Colloquium

A galactic-scale gravitational-wave detector for the biggest black holes in the universe
Sarah Burke-Spolaor
3:30pm|Virtual

A half-decade ago, LIGO first allowed us to detect gravitational waves. However, just like electromagnetic light, gravitational waves have a broad spectrum of emission frequencies over which different objects will emit. I will describe efforts in...

Mathematical Conversations

Embedding Symplectic Ellipsoids and Diophantine equations
5:30pm|Remote Access

This talk will explain work stemming from a group project that investigated the ellipsoidal embedding capacity function for the family of Hirzebruch surfaces. This problem turns out to have unexpected arithmetic structure, leading to an intricate...

Institute for Advanced Study Astrophysics Seminar

Constraints to ultralight axion dark matter particles mass: the effect of self-interactions.
Alma González-Morales
11:00am|Virtual Meeting

Ultralight axions have gained great relevance in modern cosmology, becoming a promising candidate to describe the dark matter of the Universe. Axion models in which the scalar field potential includes only the quadratic term, usually referred as the...

Princeton University Thunch Talk

A Fractal Theory of Stellar Wind Feedback in the Dense Turbulent ISM
Lachlan Lancaster
12:30pm|Virtual Meeting

Winds from massive stars have velocities of 1000 km/s or more, and produce hot, high pressure gas when they shock. We present a theory for the evolution of bubbles driven by the collective winds from star clusters, which involves interaction with...
