Title: Open Questions on the Dynamics of Black Holes
Abstract: Today we have a solid theoretical understanding of the dynamics of black
holes, as predicted by general relativity, for the typical binary merger
expected as an astrophysical gravitational wave source.
However, in more "extreme" situations, namely black holes that collide with
ultrarelativistic velocities, and black holes that spin near the maximal limit
allowed by general relativity, less is known, in some cases even qualitatively.
In this talk I will discuss some of these open questions,
and speculate about possible answers.

Title: The Gravitational Wave Transient Catalog 4.0: Overview and Highlights
Abstract: The worldwide network of gravitational-wave (GW) detectors, comprised of the Advanced LIGO, Advanced Virgo, and KAGRA detectors has been increasing in sensitivity, range, and hence quantity and quality of detected GW signals from compact binary coalescences. We present the compact binary signals observed and included in the GW Transient Catalog 4 (GWTC-4), i.e. up to and including the first part of the fourth observing run of the detectors (O4a). We estimate the source properties, and provide new insight into compact objects in binaries - and to what may lay ahead.
