From supernova feedback to Milky Way black holes: using cogsworth to perform population synthesis with galactic dynamics
Tom Wagg
11:00am|Bloomberg Lecture Hall

Abstract: Feedback from massive stars shapes the formation and evolution of galaxies, and is essential for reproducing their observed properties. The vast majority of these massive stars are formed in binaries, yet many parameters within binary...

Magnetospheric Accretion and Ejection
11:00am|Bloomberg Lecture Hall

Magnetospheric accretion is a universal process occurring in magnetized astronomical objects, ranging from neutron stars and white dwarfs to young stars (YSOs) and planets. In the context of neutron stars, this process is linked with phenomena such...

Kink Instability and Its Associated Turbulence in Astrophysical Jets
Hui Li
11:00am|Bloomberg Lecture Hall

Astrophysical jets driven by black holes are thought to undergo kink instabilities due to the large current carried by such jets. Dissipation of magnetic energy through kink instabilities has been suggested to account for the high-energy radiation...

Exoplanet Demographics from Microlensing
Scott Gaudi
11:00am|Bloomberg Lecture Hall

Gravitational microlensing is sensitive to planetary systems that cannot be probed by other techniques, in particular cold, low-mass planets beyond the snow line. Ground-based microlensing surveys have discovered over 250 planets, including roughly...

Inside Astronomically Realistic Black Holes
Andrew Hamilton
11:00am|Bloomberg Lecture Hall

I will use a real-time general relativistic Black Hole Flight Simulator to show what really happens inside astronomically realistic black holes. The inner horizon of a rotating black hole is the most violent place in the Universe, easily reaching...

Numerical Modeling of Plasmas Across Fluid and Kinetic Regimes
11:00am|Bloomberg Lecture Hall

Plasmas exhibit a wide range of behaviors across fluid and kinetic regimes, governing key processes in diverse laboratory, space, and astrophysical environments. Understanding these systems requires numerical models with varying levels of physical...

The Beating Heart of a Pulsar: Pair Plasma Creation in the Polar Caps
Andrey Timokhin
11:00am|Bloomberg Lecture Hall

The magnetospheres of pulsars are filled with dense electron–positron plasma that is responsible for essentially all their non-thermal emission. This plasma is believed to be created in electromagnetically driven electron–positron pair cascades in...

Which Microphysics Matters? The Case for Dust Dynamics
11:00am|Bloomberg Lecture Hall

Abstract: Numerical simulations of galaxies and the interstellar medium are now reaching resolutions where small-scale physical processes can be resolved directly. This raises a natural question: which pieces of microphysics must be modeled...

Improving Neutron Star Mergers with Advanced Computational Methods
11:00am|Bloomberg Lecture Hall

Continual improvements to our observational capabilities promise a wealth of data from binary neutron star systems in the coming years and decades, which will find broad applications across several fields of physics. However, the current generation...
