\textsc{SPLIT}: a robust semi-coherent inference pipeline for long-inspiral gravitational-wave sources

Shubham Kejriwal

The Laser Interferometer Space Antenna (LISA) will detect gravitational waves (GWs) from dozens of extreme- and intermediate-mass-ratio inspirals (EMRIs/IMRIs). These sources will…

Hierarchical modeling of gravitational-wave populations for disentangling environmental and modified-gravity effects

Shubham Kejriwal, Enrico Barausse, Alvin J. K. Chua

The upcoming Laser Interferometer Space Antenna (LISA) will detect up to thousands of extreme-mass-ratio inspirals (EMRIs). These sources will spend cycles in band, and…

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…

Prospects for EMRI/MBH parameter estimation using Quasi-Periodic Eruption timings: short-timescale analysis

Joheen Chakraborty, Lisa V. Drummond, Matteo Bonetti +11

Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models…

Bias-Corrected Importance Sampling for Inferring Beyond-Vacuum-GR Effects in Gravitational-Wave Sources

Shubham Kejriwal, Francisco Duque, Alvin J. K. Chua +1

The upcoming gravitational wave (GW) observatory LISA will measure the parameters of sources like extreme-mass-ratio inspirals (EMRIs) to exquisite precision. These measurements wi…
