Atlantic GR Seminar: Kam To Billy Chan (MUN)
September 30, 2020 @ 1:00 pm - 2:00 pm
The Reissner-Nordstrom Near Horizon Geometry is a Tangent Spacetime
The near horizon geometry (NHG) of an extremal Reissner-Nordstrom black hole is obtained in conventional global AdS coordinates and in the coordinates of the parent spacetime. Geometrical objects, specifically Killing vectors and spacetime points, are mapped from the boundary and horizon of the NHG into the parent spacetime coordinates. The outcome is that the NHG is a tangent spacetime to the extremal Reissner-Nordstrom black hole’s degenerate horizon and that the degenerate horizon does not bifurcate. A generalization is made for N-dimensional Reissner-Nordstrom black holes. This work is an extension of Sean Stotyn’s A Tale of Two Horizons.
The Atlantic General Relativity 2020 online postdoc/student seminar series is in the tradition of the annual AGR meetings, providing a forum not only for students and postdocs to present their research and make professional contacts but also to facilitate connections and collaborations between all Atlantic Canadian relativists. The series is student-organized and includes all areas of classical and quantum gravity. Talks will occur on the last Wednesday of every month, with each session consisting of two 30 minute talks. If you would like to attend, please email the organizers for connection details.
