No Evidence for a Dip in the Binary Black Hole Mass Spectrum
The Astrophysical JournalStellar models indicate that the core compactness of a star, which is a common proxy for its explodability in a supernova, does not increase monotonically with the star’s mass.

Modeling the Rising Tails of Galaxy Rotation Curves
Galaxies, 2019 It is well known, but under-appreciated in astrophysical applications, that it is possible for gravity to take on a life of its own in the form of Weyl-curvature-only metrics (note that we are referring to the Weyl-only solutions of ordinary General ...

Analysis of the effect of coupling coefficients on the slope of PDH-locked frequency discriminator
AIP AdvancesThe effects of the coupling coefficients on the reflected field and the error signal under various misalignments and near-axis conditions are analyzed, and some basic features of the error signal are investigated.

Do Both Black Holes Spin in Merging Binaries? Evidence from GWTC-4 and Astrophysical Implications
The Astrophysical JournalAngular momentum transport in high-mass stars is commonly modeled by extrapolating the behavior of better-observed low-mass stars. According to the conventional picture, the cores of most black hole progenitors lose almost all of their angular momentum ...

Decline of the Current Quadrupole Moment during the Merger Phase of Binary Black Hole Coalescence
Universe, 2019 Utilizing the tools of tendex and vortex, we study the highly dynamic plunge and merger phases of several π -symmetric binary black hole coalescences. In particular, we observe a decline of the strength of the current quadrupole moment compared

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection
Space WeatherTianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma ...
