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...

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...

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...

Hierarchical few body problem at High Eccentricity is a simple pendulum
11:00am|Bloomberg Lecture Hall

I will present and discuss new analytical solutions to high eccentricity perturbed Keplerian orbits undergoing Kozai-Lidov oscillations. In particular, I will show that the complex dynamics of hierarchical few body stellar systems - can be reduced...

Rethinking about gravitational instability as a planet formation scenario
Cristiano Longarini
11:00am|Bloomberg Lecture Hall

The ubiquity of substructures in protoplanetary discs has opened debate regarding the alignment of planet formation timescales with protostellar disc evolution. Under the hypothesis of the planetary interpretation, a robust conclusion is that a...

Theory for innovative cosmological tests of dark matter-baryon interactions
Yacine Ali-Haimoud
11:00am|Bloomberg Lecture Hall

Among many things, dark matter could be made of new fundamental or composite particles, which may feebly interact with nuclei or electrons (“baryons”), as well as with themselves. Cosmological observables are a promising avenue to test such...
