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.

Two-timescale evolution of extreme-mass-ratio inspirals: Waveform generation scheme for quasicircular orbits in Schwarzschild spacetime [PDF]
Physical Review D, 2020 Extreme-mass-ratio inspirals, in which a stellar-mass compact object spirals into a supermassive black hole in a galactic core, are expected to be key sources for LISA.

The Binary Mass Ratio in the Black Hole Transient MAXI J1820+070 [PDF]
Astrophysical Journal, 2020 We present intermediate-resolution spectroscopy of the optical counterpart to the black hole X-ray transient MAXI J1820+070 (=ASASSN-18ey) obtained with the OSIRIS spectrograph on the 10.4 m Gran Telescopio Canarias.

Experimentally Measured Thermal Masses of Adsorption Heat Exchangers
Energies, 2020 The thermal masses of components influence the performance of many adsorption heat pump systems. However, typically when experimental adsorption systems are reported, data on thermal mass are missing or incomplete.

Basin-scale control on N2O loss rate and emission in the Changjiang River network, China
Frontiers in Marine Science, 2022 Global riverine N2O emissions have been made by several studies with great uncertainty. However, the regional N2O budgets and patterns in large river networks is still unclear, due to the lacking understanding of in-river N2O emission rate and well ...

Detecting Scalar Fields with Extreme Mass Ratio Inspirals. [PDF]
Physical Review Letters, 2020 We study extreme mass ratio inspirals (EMRIs), during which a small body spirals into a supermassive black hole, in gravity theories with additional scalar fields.
