A Lensing-Band Approach to Spacetime Constraints
Alejandro Cárdenas-Avendaño, Aaron Held
General relativity's prediction that all black holes are described by the Kerr metric, irrespective of their size, can now be empirically tested using electromagnetic observations…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Challenges in Quasinormal Mode Extraction: Perspectives from Numerical solutions to the Teukolsky Equation
Hengrui Zhu, Justin L. Ripley, Alejandro Cárdenas-Avendaño +1
The intricacies of black hole ringdown analysis are amplified by the absence of a complete set of orthogonal basis functions for quasinormal modes. Although damped sinusoids effect…
Prediction for the interferometric shape of the first black hole photon ring
Alejandro Cárdenas-Avendaño, Alexandru Lupsasca
Black hole images are theoretically predicted (under mild astrophysical assumptions) to display a stack of lensed "photon rings" that carry information about the underlying spaceti…
