Cosmic Mashups: From Galaxies to Black Holes

When
-

Abstract:  From the galaxy mergers that trigger new star formation and black hole growth, to the black hole mergers that produce gravitational waves, mergers are fundamental drivers of the evolution of our Universe. The first pulsar timing array observations of gravitational waves, which were announced earlier this year, offer a new opportunity to crack open the mysteries of how galaxy mergers lead to supermassive black hole mergers.

Cleaning up the dusty universe with JWST and ALMA

When
-

Abstract: About half the light ever emitted by stars over the course of the history of the universe was absorbed by interstellar dust and re-radiated at long wavelengths. Dust-rich galaxies, extremely faint in visible light images, are the sites of intense starbursts that can rapidly assemble and then cut short the growth of the earliest generations of massive galaxies.

APS Round Robin Colloquium

When
-

Please join us for a very special Round Robin Colloquium. For those of you who are unfamiliar, for the Round Robin Colloquium, all members and affiliates of the APS department who are able are invited to add a slide to the slide deck and will have one minute to introduce themselves to the department.  This is a great way to get to know everyone in the huge and fabulous APS department.

As usual, please join us in the APS office at 11:45 for coffee, snax, and fun. 

 

More than physics, more than data: Integrated machine-learning models for chemistry

When
-

Abstract: Machine-learning techniques are often applied to perform "end-to-end" predictions, that is to make a black-box estimate of a property of interest using only a coarse description of the corresponding inputs.
In contrast, atomic-scale modeling of matter is most useful when it allows to gather a mechanistic insight into the microscopic processes that underlie the behavior of molecules and materials. 

Quantum Simulation - from Dipolar Quantum Solids to Kinetic Nagaoka Ferromagnetism

When
-

Abstract: Quantum simulations with ultracold atoms in optical lattices enter the next phase, in which we can extend bosonic and fermionic Hubbard models in a wide range of ways. I will present recent results in which we realized strongly correlated dipolar quantum gases and observed quantum-phase transitions to stripe and checkerboard phases.
