Core-collapse of fast rotators in the early universe

Abstract:
It is widely believed that the fast rotation of a massive star affects the dynamics of core-collapse and eventually results in the most luminous event in the present universe, the long gamma-ray burst (LGRB). Another important consequence of the fast rotation would be an energetic supernova explosion, which is often observed to be associated with LGRBs.
Stellar compact mergers as progenitors of short-gamma ray bursts

Event type
Stellar Compact object mergers are not only important sources of gravitational waves but also central engines that power electromagnetic transients and r-processes, if matter is involved. I will review recent progress modeling the merger of black hole-neutron star and neutron stars binaries highlighting state-of-the-art general relativistic hydrodynamic simulations.
Kerr (smooth) deviations and Symmetries

Event type
A novel approach in constructing deviations of the Kerr spacetime whereas
the symmetries can be preserved is presented. The method was applied
trivially in all known classical black-hole spacetimes tested, while
provides the possibility of testing and inventing deformations of Kerr in
a quick and innovative way. The methodology is based on earlier work by
