The Self-force on Static and Dynamic Charges in Schwarzschild Spacetime Using the Method of Images
Alan Wiseman, Assoc. Professor, Dept. of Physics, UW-Milwaukee
One of the most basic examples of a self-force phenomenon (sometimes called the radiation reaction force) is that of a small, charged particle near a large spherical mass such as a Schwarzschild black hole. If the particle is held stationary, there are novel electrostatic forces on the particle. If the particle is orbiting the mass, the fields created by the particle back-react on the particle and cause it to depart from its otherwise free-fall motion. There are many ways to solve for the forces and motion in these circumstances, but past solutions have involved considerable technical machinery, and the results are messy and "non-intuitive".

New Opportunities in Single-particle Cryo-EM: Mapping States in an Ensemble, Trapping Short-lived States
Single-particle cryo-EM provides experimental access to large ensembles of biological molecules, but current methods of analysis fall short of mining the rich information buried in the data sets.

Among the great surprises of modern cosmology was the discovery of Dark Energy. In this talk, I will introduce the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an ambitious project to study Dark Energy by tracing out 4 billion years of cosmic history, using a purpose-built radio telescope at the Dominion Radio Astrophysical Observatory
