Leviathan: a very massive, extended sub-millimetre galaxy spectroscopically confirmed at
William M. Baker, Francesco Valentino, Jens Hjorth +5
We present Leviathan, a sub-millimetre galaxy (SMG) spectroscopically confirmed at with JWST/NIRSpec. Modelling 31 bands of photometry from the rest-frame ultraviolet to…
Constraining the geometry of rotating black holes with eikonal QNMs
Ciro De Simone, Sebastian H. Völkel, Kostas D. Kokkotas
Quasinormal modes of black holes provide a central avenue for confronting general relativity with gravitational-wave observations from the ringdown stage of compact binary coalesce…
Optimal frequency scales for probing black-hole geometries
Saulo Albuquerque, Sebastian H. Völkel
Can gravitational waves probe the near-horizon geometry of black holes, and if yes, which frequency scale is optimal? Although shorter wavelengths usually resolve smaller scales, w…
Constraining deviations from the Teukolsky equation with GW250114
Sebastian H. Völkel, Nicola Franchini
The recent gravitational-wave detection GW250114 by the LIGO-Virgo-KAGRA (LVK) Collaboration provides unprecedented precision for testing general relativity (GR) through black hole…
Parametrized beyond-Teukolsky framework in the time domain
Ciro De Simone, Sebastian H. Völkel, Kostas D. Kokkotas +1
Modifications to General Relativity can significantly alter the perturbative response of black holes, leaving imprints on quasinormal-mode spectra, waveform amplitudes and phases,…
