Gravitational waves from single neutron stars: an advanced detector era survey

open access: yes, 2018
With the doors beginning to swing open on the new gravitational wave astronomy, this review provides an up-to-date survey of the most important physical mechanisms that could lead to emission of potentially detectable gravitational radiation from ...

Quantum Dust Cores of Black Holes and Their Quasi‐Normal Modes

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
We investigate the quasi‐normal mode spectrum of a gravitationally collapsed ball of dust, considering both a linear and a refined parabolic effective mass function for the quantum core. Furthermore, we account for the quantum leakage of dust particles outside the horizon.

Alternative Approach to Tilt-to-Length Coupling Estimation for Laser Ranging Interferometers in Future Gravity Missions

open access: yesRemote Sensing
Tilt-to-length coupling, a non-constant systematic error source caused by satellite attitude variations, has been observed in the laser ranging signals of the GRACE Follow-On mission. This error can be corrected by certain calibration maneuvers performed

Challenges and Opportunities for National‐Scale Projections of Future Coastal Landscape Change

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Local to global scale projections of future coastal landscape change are essential to improve land and resource management decisions that aim to prepare for and reduce risk exposure to impending coastal hazards. However, the availability of actionable knowledge is often limited due to the complexity of drivers of change, their consequences ...

Long Term Assimilation of Directional Wave Data From CFOSAT in the Wave Prediction Model MFWAM

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Recently, satellite wave observations have stepped forward with the innovative measurements from the wave scatterometer SWIM of the CFOSAT mission which provides both the significant wave height (SWH) along‐track at nadir look and the directional wave spectra on off‐nadir incidence angle.

Determining Magnetic Field Intensity and Direction From the Anisotropy of Magnetic Remanence in Sediments

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Anisotropy of magnetic remanence (AMR) holds promise for quantifying relative paleointensity values from sedimentary rocks. A proof of concept was established for applied fields that exceeded the intensity of the geomagnetic field. Under Earth‐like fields, large uncertainties necessitate the development of a new approach to improve the ...

Equiaffine Braneworld

open access: yesGalaxies, 2020
Higher dimensional theories, wherein our four dimensional universe is immersed into a bulk ambient, have received much attention recently, and the directions of investigation had, as far as we can discern, all followed the ordinary Euclidean hypersurface

Statistical Study of Short Large‐Amplitude Magnetic Structures at Mars Observed by MAVEN

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a statistical study of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Martian foreshock using data from the Mars Atmosphere and Volatile Evolution (MAVEN) mission between 01 January 2015 and 31 December 2019. We have identified 21,008 SLAMS during this time interval and statistical results are presented on the SLAMS ...
