Scientific progress in JETSET is built on long-term dedication and teamwork. We are happy to announce that Konrad Topolski has successfully completed his PhD !
We congratulate Konrad on reaching this milestone and thank him for the enthusiasm and rigor he contributed to the group. He shaped the group not only through scientific achievements, but also through mentoring younger students and contributing to code development.
Konrad’s research investigated black hole–neutron star mergers across a wide range of mass ratios and black-hole spins. He systematically identified the conditions that distinguish direct plunge from tidal disruption. By combining quasi-equilibrium models with high-resolution dynamical simulations, he established robust criteria for disk formation, gravitational-wave signatures, and possible electromagnetic counterparts. His work provided key insights for multi-messenger astrophysics. He also showed that features of the post-merger gravitational-wave spectrum follow quasi-universal relations, helping constrain neutron-star matter through GW observations.
We wish Konrad all the best and continued success in his scientific career.
