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 ...

The Impact of a Long‐Lived Basal Magma Ocean on the Thermochemical Evolution of Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract A basal magma ocean (BMO) has been suggested to form as a consequence of cumulate overturn following crystallization of an initial global magma ocean. As a consequence of enrichment in iron and heat‐producing elements (HPE), the BMO stabilizes gravitationally at the base of the planetary mantle, affecting the efficiency of mantle convection ...

Dealing with data gaps for TianQin with massive black hole binary signal

European Physical Journal C: Particles and Fields
Space-borne gravitational wave detectors like TianQin might encounter data gaps due to factors like micro-meteoroid collisions or hardware failures. Such events will cause discontinuity in the data, presenting challenges to the data analysis for TianQin,

Gravitational Waves Astronomy: a cornerstone for gravitational theories

, 2010
Realizing a gravitational wave (GW) astronomy in next years is a great challenge for the scientific community. By giving a significant amount of new information, GWs will be a cornerstone for a better understanding of gravitational physics. In this paper

Thermal Precursors to Regional Dust Storms on Mars: Observations With Mars Climate Sounder

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Surface heating by solar flux is an important mechanism in driving atmospheric instability and dust lifting on Mars. We investigated possible signals of elevated surface temperatures and surface flux prior to regional Mars dust storms using Mars Climate Sounder data.

On the Origins of Mercury's Sodium Exospheric Cold Poles Enhancement: A Multiscale Exosphere Global Model

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Mercury's exosphere is sustained by the continuous ejection of atoms from its surface, driven by solar wind, micro‐meteoroid impacts, and surface heating. Due to its 3:2 spin‐orbit resonance, some longitudes experience greater solar exposure, creating temperature variations from ∼90 to 700 K.

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 Importance of Seasonality in Seagrass Properties for Coastal Hydro‐Morphodynamics—A Case Study in a Wadden Sea Basin

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 11, November 2025.
Abstract Seagrass meadows fulfill many essential ecological functions, of which an important one is to stabilize sediment. Therefore, they are perceived as a nature‐based addition or alternative to conventional rigid coastal protection. The impact of seagrass meadows depends on their morphology, such as canopy height, shoot density, and spatial extent.
