Detecting fundamental fields with LISA observations of gravitational waves from extreme mass-ratio inspirals [PDF]
Nature Astronomy, 2021 The Laser Interferometer Space Antenna1, LISA, will detect gravitational wave signals from extreme mass-ratio inspirals2, where a stellar mass compact object orbits a supermassive black hole and eventually plunges into it.

Gravitational-Wave Energy Flux for Compact Binaries through Second Order in the Mass Ratio. [PDF]
Physical Review Letters, 2021 Within the framework of self-force theory, we compute the gravitational-wave energy flux through second order in the mass ratio for compact binaries in quasicircular orbits.

Primordial extreme mass-ratio inspirals
Physics Letters BThe coalescence of stellar-mass primordial black holes (PBHs) might explain some of the gravitation waves (GWs) events detected by LIGO-Virgo-KAGRA. On the other hand, observational hints for supermassive PBHs (SMPBHs) have been accumulated.

Dynamic Response Analysis of Mega-Sub Isolated Structures under Multiaxial Earthquakes
Applied Sciences, 2023 With the use of seismic isolation techniques on mega-sub structures, several scholars have carried out research on them. However, little research has been carried out on mega-sub isolated structures under multiaxial earthquakes. There have been instances

Gravitational Wave Glitches in Chaotic Extreme-Mass-Ratio Inspirals. [PDF]
Physical Review Letters, 2021 The Kerr geometry admits the Carter symmetry, which ensures that the geodesic equations are integrable. It is shown that gravitational waveforms associated with extreme-mass-ratio inspirals involving a nonintegrable compact object display "glitch ...

Mass-ratio and Magnetic Flux Dependence of Modulated Accretion from Circumbinary Disks [PDF]
Astrophysical Journal, 2021 Accreting supermassive binary black holes (SMBBHs) are potential multimessenger sources because they emit both gravitational-wave and electromagnetic (EM) radiation.
