Machine Learning for the Characterization of Gravitational Wave Data

, 2021
The low-latency characterization of detector noise is a crucial step in the detection of gravitational waves. In particular, a rapid classification and identification of transient noise sources, usually referred to as glitches, is very important when ...

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 ...

Wavefront Selective Modal Excitations for Optimally Informative Sensing in Fano‐Resonant Metasurfaces

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Structured illuminations can unlock hidden quasi‐BIC modes in Fano‐resonant metasurfaces, enhancing the sensitivity to nanoscale perturbations. By analyzing the eigenmode spectrum of a dielectric metasurface and applying information theory, tailored wavefronts can be engineered that selectively excite otherwise inaccessible modes.

Do Both Black Holes Spin in Merging Binaries? Evidence from GWTC-4 and Astrophysical Implications

The Astrophysical Journal
Angular 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 ...

Analysis of the effect of coupling coefficients on the slope of PDH-locked frequency discriminator

AIP Advances
The 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.

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
