Mass-gap extreme mass ratio inspirals
Physical Review D, 2022 In this work, we propose a new subclass of extreme-mass-ratio-inspirals (EMRIs): mass-gap EMRIs, consisting of a compact object in the lower mass gap $\sim (2.5-5) M_\odot$ and a massive black hole (MBH). The mass-gap object (MGO) may be a primordial black hole or produced from a delayed supernova explosion.

GW190521 May Be an Intermediate-mass Ratio Inspiral [PDF]
Astrophysical Journal, 2020 GW190521 is the first confident observation of a binary black hole merger with total mass . Given the lack of observational constraints at these masses, we analyze GW190521 considering two different priors for the binary’s masses: uniform in mass ratio ...

Applied Sciences, 2021 When high-rise buildings are shaken due to external forces, the facilities of the building can be damaged. A Tuned Mass Damper (TMD) can resolve this issue, but the seismic resistance of TMD is exhausted due to the detuning effect.
