SPLIT: Loosely-coherent inference of long-inspiral gravitational-wave sources for robustness against modeling and data outliers

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…

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…

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…

Constraining accretion physics with gravitational waves from eccentric extreme-mass-ratio inspirals

Francisco Duque, Shubham Kejriwal, Laura Sberna +2

We study the evolution of eccentric, equatorial extreme-mass-ratio inspirals (EMRIs) immersed in the accretion disks of active galactic nuclei. We find that single gravitational-wa…

Alive and Strongly Kicking: Stable X-ray Quasi-Periodic Eruptions from eRO-QPE2 over 3.5 Years

Dheeraj Pasham, Shubham Kejriwal, Eric Coughlin +5

Quasi-periodic eruptions (QPEs) are recurring bursts of soft X-rays from the nuclei of galaxies. Their physical origin is currently a subject of debate, with models typically invok…
