The Fast and the Frame-Dragging: Efficient waveforms for asymmetric-mass eccentric equatorial inspirals into rapidly-spinning black holes
Christian E. A. Chapman-Bird, Lorenzo Speri, Zachary Nasipak +13
Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient wav…
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…
Measuring source properties and quasi-normal-mode frequencies of heavy massive black-hole binaries with LISA
Alexandre Toubiana, Lorenzo Pompili, Alessandra Buonanno +2
The laser-interferometer space antenna (LISA) will be launched in the mid 2030s. It promises to observe the coalescence of massive black-hole (BH) binaries with signal-to-noise rat…
Fast and Fourier: Extreme Mass Ratio Inspiral Waveforms in the Frequency Domain
Lorenzo Speri, Michael L. Katz, Alvin J. K. Chua +5
Extreme Mass Ratio Inspirals (EMRIs) are one of the key sources for future space-based gravitational wave interferometers. Measurements of EMRI gravitational waves are expected to…
Is there an excess of black holes around ? Optimising the complexity of population models with the use of reversible jump MCMC
Alexandre Toubiana, Michael L. Katz, Jonathan R. Gair
Some analyses of the third gravitational wave catalogue released by the LIGO-Virgo-KAGRA collaboration (LVK) suggest an excess of black holes around . In order to…
