Black Hole Spectroscopy
Abstract: According to general relativity, the remnant of a binary black hole merger should be a perturbed Kerr black hole. Perturbed Kerr black holes emit “ringdown” radiation which is well described […]

Global existence and stability of de Sitter-like solutions to the Einstein-Yang-Mills equations in spacetime dimensions n≥4
Abstract: In this talk, we briefly introduce our recent work on establishing the global existence and stability to the future of non-linear perturbation of de Sitter-like solutions to the Einstein-Yang-Mills […]
Future stability of the $1+3$ Milne model for the Einstein-Klein-Gordon system
Abstract: We study the small perturbations of the $1+3$-dimensional Milne model for the Einstein-Klein-Gordon (EKG) system. We prove the nonlinear future stability, and show that the perturbed spacetimes are future […]
A new proof for the nonlinear stability of slowly-rotating Kerr-de Sitter
Abstract: The nonlinear stability of the slowly-rotating Kerr-de Sitter family was first proven by Hintz and Vasy in 2016 using microlocal techniques. In my talk, I will present a novel […]

General Relativity Seminar Speaker: Professor Harvey Reall (University of Cambridge) Title: The second law of black hole mechanics in effective field theory Abstract: I shall discuss the second law of black hole […]
The Gregory-Laflamme instability of black strings revisited
General Relativity Seminar Title: The Gregory-Laflamme instability of black strings revisited Abstract: In this talk I will discuss our recent work that reproduces and extends the famous work of Lehner and Pretorius on the […]
A scale-critical trapped surface formation criterion for the Einstein-Maxwell system
https://youtu.be/1v9STFWqArQ General Relativity Seminar Speaker: Nikolaos Athanasiou Title: A scale-critical trapped surface formation criterion for the Einstein-Maxwell system Abstract: Few notions within the realm of mathematical physics succeed in capturing […]
General-relativistic viscous fluids
https://youtu.be/nfausHrja-Y General Relativity Seminar Speaker: Marcelo Disconzi, Vanderbilt University Title: General-relativistic viscous fluids Abstract: The discovery of the quark-gluon plasma that forms in heavy-ion collision experiments provides a unique opportunity to study the properties of matter under […]
Duality in Einstein’s Gravity
General Relativity Seminar Speaker: Uri Kol, CMSA Title: Duality in Einstein’s Gravity Abstract: Electric-Magnetic duality has been a key feature behind our understanding of Quantum Field Theory for over a century. In […]
Strong Cosmic Censorship
https://youtu.be/6tjqDpT9f-k General Relativity Seminar Speaker: Professor Oscar Dias (University of Southampton) Title: Strong Cosmic Censorship Abstract: Generically, strong cosmic censorship (SCC) is the statement that physics within general relativity should be predicted from […]
Love Symmetry of Black Holes
https://youtu.be/tpmm618NjtE General Relativity Seminar Speaker: Sergei Dubovsky (New York University) Title: Love Symmetry of Black Holes Abstract: Perturbations of massless fields in the Kerr-Newman black hole background enjoy a ("Love") SL(2,ℝ) […]
Gravitational Wave, Angular Momentum, and Supertranslation Ambiguity
General Relativity Seminar Speaker: Naqing Xie (Fudan University) Title: Gravitational Wave, Angular Momentum, and Supertranslation Ambiguity Abstract: The supertranslation ambiguity of angular momentum is a long-standing and conceptually important issue in general […]
