Gravitational shockwaves on rotating black holes
Yoni BenTov, Joe Swearngin
We present an exact solution of Einstein's equation that describes the gravitational shockwave of a massless particle on the horizon of a Kerr-Newman black hole. The backreacted me…
Classification of Electromagnetic and Gravitational Hopfions by Algebraic Type
Amy Thompson, Alexander Wickes, Joe Swearngin +1
We extend the definition of hopfions to include a class of spin- fields and use this to introduce the electromagnetic and gravitational hopfions of different algebraic types. Th…
Linked and Knotted Gravitational Radiation
Amy Thompson, Joe Swearngin, Dirk Bouwmeester
We show that the torus knot topology is inherent in electromagnetic and gravitational radiation by constructing spin- fields based on this topology from the elementary states of…
Gravitational Hopfions
Joe Swearngin, Amy Thompson, Alexander Wickes +2
The electromagnetic hopfion (EM hopfion) is a topologically nontrivial solution to the vacuum Maxwell equations with the property that any two field lines belonging to either the e…
