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 […]
Title: Effective Field Theory Breakdown Near Cool Black Holes Abstract: In this talk, I will demonstrate a surprising way in which near-extremal black holes are sensitive probes of new physics. For extremal Kerr black holes, higher-derivative corrections cubic and quartic in the Riemann tensor induce tidal force singularities on the horizon, leading to a breakdown […]
Title: New Structures in the J/psi J/psi Mass Spectrum at CMS Abstract: The speaker will discuss the new structures reported by the CMS collaboration recently. Three structures are found in the J/psi J/psi mass spectrum in proton-proton collisions at 13 TeV, and a model with quantum interference among these structures provides a good description of […]
Erik Tollerud (STScI) "Dwarf Galaxies, Near-Field Cosmology, and Software: It's All Connected"
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
Speaker 1: Kurmanbek Kaiyrbekov (from Brian Camley’s group) - Does nematic order allow groups of elongated cells to sense electric fields better? Speaker 2: Aniruddh Murali (from Francesca Serra’s group at SDU) – Cells around corners https://jhubluejays.zoom.us/j/93026415427?pwd=ZGo1ditSNjh6V1JFY2dWNlhTOStLQT09
Interphase Chromatin Undergoes a Local Sol-Gel Transition Upon Cell Differentiation Cell differentiation, the process by which stem cells become specialized cells, is associated with chromatin reorganization inside the cell nucleus. Here, we measure the chromatin distribution and dynamics in embryonic stem cells in vivo before and after differentiation. We find that undifferentiated chromatin is less compact, more […]
Special Condensed Matter Seminar Speaker: Allen Scheie Title: "The old and the new: Probing elemental gadolinium and quantum entanglement with neutron scattering" Abstract: Doing experiments on quantum materials often not nearly as hard as interpreting those experiments. In this talk I discuss two projects where neutron scattering data was analyzed in a new way to […]

Title: Beyond LCDM: New constraints on new components Abstract: Are dark matter and dark energy the only cosmological constituents that lie beyond the Standard Model? It has been suggested that dark matter and dark energy are parts of a more extensive hidden sector that includes additional particles and fields. Since there are no direct observational […]
