Double Neutron Star Delay Times Across Cosmic Metallicities: The Role of Helium Star Progenitors

Abhishek Chattaraj, Jeff J. Andrews, Max Briel +5

Metallicity can play a significant role in massive binary evolution through its impact on the opacity within stellar interiors and wind-driven mass loss. In this work, we investiga…

Pseudospectrum and (in)stability of black hole total transmission modes

Yu-Sen Zhou, Ming-Fei Ji, Liang-Bi Wu +1

Total transmission modes (TTMs) are modes with complex frequencies that propagate across a black hole spacetime without reflection. Recently, it is found that suitably tailored tim…
