Jordan Moxon will discuss: "Self force on a scalar charge in Kerr spacetime: inclined circular orbits" http://arxiv.org/abs/1408.2885 

Robert Wharton will discuss: "Theory and Simulations of Refractive Substructure in Resolved Scatter-Broadened Images" http://arxiv.org/abs/1502.05722 and how it may affect observations with the Event Horizon Telescope, as described in the following two papers: http://arxiv.org/abs/1409.0530 "Discovery of Substructure in the Scatter-broadened Image of Sgr A*" http://arxiv.org/abs/1409.4690 "Imaging an Event Horizon: Mitigation of Scattering toward Sagittarius A*"
