Global fits of simplified models for dark matter with GAMBIT II. Vector dark matter with an -channel vector mediator
Christopher Chang, Pat Scott, Tomás E. Gonzalo +2
Global fits explore different parameter regions of a given model and apply constraints obtained at many energy scales. This makes it challenging to perform global fits of simplifie…

Spinning up a Time Machine
T. C. Ralph, Chris Chang
We present a global metric describing closed timelike curves embedded in Minkowski spacetime. Physically, the metric represents an Alcubierre warp drive on a rotating platform. The…
