Testing Dark Energy with Black Hole Ringdown
Laurens Smulders, Johannes Noller, Sergi Sirera
We show that dynamical dark energy theories can imprint modifications on the quasi-normal mode (QNM) spectrum characterising black hole ringdown. The time dependence of dyna…

Stable black hole solutions with cosmological hair
Laurens Smulders, Johannes Noller
Dynamical dark energy theories generically introduce a time-dependent field that causes the accelerated expansion of the Universe on large scales. When embedding black hole solutio…
