Title: Topological Resummation in Quantum Gravity, Abstract: The gravitational path integral remains one of the most elusive constructs in quantum gravity, particularly in regimes dominated by topological fluctuations. In this talk, I will present recent progress in Jackiw–Teitelboim (JT) gravity, where the sum over geometries can be made precise. We demonstrate that in a low-temperature […]
ML x Astro/Cosmo meetings are geared towards discussing new methods/ideas at the intersection of machine learning and astrophysics/cosmology.
Observing the Circum(sub)stellar Environments of Low-mass Stars, Brown Dwarfs, and Planets Title to be announced soon,
Black (hole) Coffee is a space for students, postdocs, and professors to discuss cutting-edge research on all things black holes, spanning both observations and theory.
Title: When black hole perturbation theory meets scattering amplitudes and conformal field theory Abstract: The study of black hole perturbation theory has seen a resurgence in recent years after the observation of the gravitational waves generated by the coalescence of binary black holes. In this talk, I will summarize some of the recent progress in […]

The Mysterious Nature of Little Red Dots Guillermo Barro (University of the Pacific)
Title: Modern Probes of Quantum Magnets Abstract: In this talk, I will highlight subtleties as well as new opportunities in probes of quantum magnetism using the recently developed technique of 2D Coherent Spectroscopy (2DCS) as well as the well-established tool of Raman spectroscopy. In the first part of the talk, I will demonstrate how magneto-electric and […]
Galaxy weak lensing with DESI While DESI has already delivered exciting results from its BAO measurements as well as full-shape galaxy clustering analyses, it also has compelling synergies with other observations, particularly, the weak lensing surveys. In this talk, I will present an overview of the science done by DESI galaxy weak lensing group, showcasing […]
The 2025 Cosmology Summer Fest is in honor of Marc Kamionkowski and Robert Caldwell’s (Dartmouth) 60th birthdays. The event will be a 2.5-day science workshop that will feature talks on a range of topics surrounding theoretical and data-driven cosmology. The workshop will take place in the auditorium and lobby of the Bloomberg Center for Physics […]
Novel Nanophotonic Devices based on Strong Light-Matter Interaction I will talk about two topics: advancing nanolasers based on photonic topological cavities and strain-induced single-photon emitters in atomically thin semiconductors. (1) Advancing nanolasers based on photonic topological cavities : Optical vector vortex beams provide additional degrees of freedom for spatially distinguishable channels in data transmission. Although […]
