The moduli space of dynamical spherically symmetric black hole spacetimes and the extremal threshold
Yannis Angelopoulos, Christoph Kehle, Ryan Unger
In this paper, we give a complete description of the black hole threshold, locally near the Reissner-Nordström family, in the infinite-dimensional moduli space of dyn…
Semilinear wave equations on extremal Reissner-Nordström black holes revisited
Yannis Angelopoulos, Ryan Unger
We revisit global existence and decay for small-data solutions of semilinear wave equations on extremal Reissner-Nordström black hole backgrounds satisfying the classical null cond…
Nonlinear stability of extremal Reissner-Nordström black holes in spherical symmetry
Yannis Angelopoulos, Christoph Kehle, Ryan Unger
In this paper, we prove the codimension-one nonlinear asymptotic stability of the extremal Reissner-Nordström family of black holes in the spherically symmetric Einstein-Maxwell-ne…
A note on Huisken's isoperimetric mass
Jeffrey L. Jauregui, Dan A. Lee, Ryan Unger
In this short note, we explain that Huisken's isoperimetric mass is always nonnegative for elementary reasons.
Extremal black hole formation as a critical phenomenon
Christoph Kehle, Ryan Unger
In this paper, we prove that extremal black holes arise on the threshold of gravitational collapse. More precisely, we construct smooth one-parameter families of smooth, sphericall…
