Singular excitement beyond the horizon of a rotating black hole
Sijia Wang, MarÃa Rosa Preciado-Rivas, Massimiliano Spadafora +1
Previous studies have shown that an Unruh-DeWitt (UDW) detector, when coupled linearly to a massless scalar field and permitted to fall radially into certain black holes, will exhi…

More Excitement Across the Horizon
MarÃa R. Preciado-Rivas, Manar Naeem, Robert B. Mann +1
An Unruh-DeWitt (UDW) detector falling radially into a four-dimensional Schwarzschild black hole, coupled linearly to a massless scalar field that has been prepared in the Hartle-H…
