Testing space-time non-commutativity with TianQin
European Physical Journal C: Particles and FieldsThe direct detection of gravitational waves offers a powerful tool to explore the nature of gravity and the structure of space-time. This paper focuses on the capabilities of space-based gravitational wave detectors in testing space-time non ...

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 ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

On the Electromagnetic Energy Flow Along Geodesics
Radio Science, Volume 61, Issue 1, January 2026.Abstract We present a field‐theoretic framework for modeling electromagnetic energy propagation in heterogeneous media by introducing the concept of electromagnetic geodesics. Unlike traditional ray optics, which assumes either a straight‐line propagation or a simple bending in refractive media, our approach formulates wave propagation as geodetic ...

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.

Gravitational wave astronomy - astronomy of the 21st century [PDF]
, 2011 An enigmatic prediction of Einstein's general theory of relativity is gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein ...

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

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.
