Speaker: William D. Ratcliff of NIST Title: "Applications of Artificial Intelligence to Neutron Scattering” Abstract: Neutron scattering is a versatile technique for studying the structure and dynamics of materials. Unfortunately, there are a limited number of neutron sources available in the world to perform scientific experiments. In this talk, I will discuss the use of […]
Title: Generative transformers and how to evaluate them Abstract: With the increase in luminosity and detector granularity, simulation will be a significant computational challenge in the upcoming high-luminosity era of the CERN Large Hadron Collider (LHC). To tackle this, I present developments in graph- and attention-based machine learning (ML) models for generating jets at the LHC using […]
Daniella Bardalez Gagliuffi (Amherst) "The New Directly Imaged Planets and Their Substellar Analogs"
15-20 min long talks on astronomy-related papers, projects, ideas. Enjoy both Astronomy and Coffee (please bring your own mugs). If you have new results, ideas or want to discuss an interesting paper from arXiv, we encourage you to present. Spring 2024 schedule
Department-wide colloquium Speaker: Stephen Taylor (Vanderbilt) Title: The Road Ahead For Nanohertz-frequency Gravitational-wave Astrophysics Abstract: The landscape of gravitational-wave astrophysics was recently broadened to encompass the nanohertz-frequency band, where NANOGrav and other pulsar-timing arrays found the tell-tale signature of a stochastic all-sky background of gravitational waves. With this evidence came spectral information that yields insights […]
Video of the talk Title: Novel strategies for hardware-efficient quantum processors Abstract: Quantum error correction is an exciting scientific frontier at the interface of many fields including quantum information science, many-body physics, and computer science. The field has developed rapidly in the last several years, with major milestones marking the first glimpses into a future of error-corrected […]
Informal science discussions and coffee, open to the entire department.
We meet every Tuesday at 1pm, Eastern time, in the CafeCon (the conference room next to the STScI cafeteria), and also remotely using BlueJeans. We start with a talk by guest speaker for ~30 minutes, followed by paper discussion. Vote for what papers you want discussed on Benty-Fields. Sign up for e-mails by sending a […]
The Simplicity, Unity and Complexity of Life from the Biosphere to the Anthroposphere Although Life is probably the most complex and diverse phenomenon in the Universe, having evolved by the “random” forces of natural selection, many of its most fundamental characteristics scale with size in a remarkably simple universal fashion. From lifespans and growth rates […]

“Opening The Era of Exoplanet Atmospheric Chemistry With JWST.” We are now one full year into the era of JWST, NASA’s flagship observatory and successor to the Hubble Space Telescope. Exoplanet characterization has historically been dominated by space-based facilities, and the new infrared capabilities of JWST are uncovering the atmospheres of exoplanets in an […]
