Astrophysics Seminar: High-resolution images of light dark matter — First results of the DAMIC-M experiment
Radomir Smida (University of Chicago)
The DAMIC-M experiment will exploit the sub-electron resolution capabilities of skipper charge-coupled devices (CCDs) to search for light dark matter particles in a broad range of masses from 1 eV to 10 GeV. A…
Experimental Particle Physics Seminar: Exotic Higgs decays & AI triggers at the LHC
Tae Min Hong (CERN)
Data at the LHC allows us to probe whether the Higgs boson communicates with unknown and/or undiscovered sectors beyond the Standard Model. I will discuss ATLAS results on the searches for Higgs decays to dark matter…
Condensed and Living Matter Seminar: Non-reciprocal pattern formation
M. Cristina Marchetti (UC Santa Barbara)
Spatio-temporal patterns in nonlinear oscillatory and excitable media have been studied extensively in systems lacking conserved quantities. More recently, pattern formation of conserved fields has…
High Energy Theory Seminar: Making massive spin-2 particles from gravity during and after inflation
Andrew Long (Rice University)
The phenomenon of cosmological gravitational particle production (CGPP) occurs during and after inflation as quantum fields “feel” the cosmological expansion are excited out of their ground state. CGPP is a…

Astrophysics Seminar: SPHEREx: An all-sky near-infrared spectral survey
Howard Hui (Caltech)
SPHEREx, an upcoming NASA medium-class Explorer Mission, will perform the first all-sky near infrared spectral survey. With a targeted launch date in early 2025, SPHEREx will map the entire sky at 6.2 arcsec from 0.…
High Energy Theory Seminar: Black Holes as the 21st century laboratory: New Tools and Prospects
Alfredo Guevara González (Harvard)
Recent breakthrough observations of black holes call for a new conceptual framework that unifies their analysis, from gravitational wave production to VLBI imaging of the photon ring. I will show how this is achieved…
Condensed and Living Matter Seminar: Orientational Order in Biological Development - Superfluid Shrimp
Mark Bowick (Kavli Institute for Theoretical Physics, UC Santa Barbara)
Morphogenesis, the process through which genes generate form, establishes tissue scale order as a template for constructing the complex shapes of the body plan. The extensive growth required to build…
Astrophysics Seminar: Synergies Between Imaging and Spectroscopic Surveys for Cosmology
Current and forthcoming sky surveys promise to deliver
datasets orders of magnitude better in quality and size than their
predecessors, but our ability to take advantage of these datasets is
