Pseudoplane-wave gravitational calibrator for gravitational wave observatories

Physical Review D, 2023
The precisions of existing gravitational calibrators for gravitational wave observatories are limited by their dependence on the relative position between the calibrators and the observatory's test masses. Here we present a novel geometry consisting of four quadrupole rotors placed at the vertices of a rectangle centered on the test mass.

A wind environment and Lorentz factors of tens explain gamma-ray bursts X-ray plateau

Nature Communications, 2022
The origin of the plateau observed in the early X-ray light curves of gamma ray bursts (GRBs) is debated. Here, the authors show that the observed plateau can be explained within the classical GRB model by considering expanding shell with initial Lorentz

Improvement of the Target Sensitivity in DECIGO by Optimizing Its Parameters for Quantum Noise Including the Effect of Diffraction Loss

Galaxies, 2021
The DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO) is the future Japanese, outer space gravitational wave detector. We previously set the default design parameters to provide a good target sensitivity to detect the primordial ...

Future Changes in the Annual Sea‐Level Cycle

Earth's Future, Volume 14, Issue 1, January 2026.
Abstract Recent projections indicate that the range of the annual sea‐level cycle (ASLC) may increase, affecting flood risk, groundwater, and ecosystems. However, existing projections have several limitations, such as their exclusion of the inverse‐barometer effect, their uncertainty due to internal variability, and/or their regional focus. Furthermore,

First search for gravitational waves from the youngest known neutron star [PDF]

, 2010
We present a search for periodic gravitational waves from the neutron star in the supernova remnant Cassiopeia A. The search coherently analyzes data in a 12 day interval taken from the fifth science run of the Laser Interferometer Gravitational-Wave ...

Evidence of Subduction, Collision, and Extension in Northern Borneo: Constraints From Receiver Functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract What happens when subduction stops is a key, but poorly understood, part of the tectonic cycle. Northern Borneo (Sabah) with a complex geological history of multiple episodes of subduction, magmatism, uplift, subsidence, and extension since the Mesozoic, is an ideal location for studying post‐subduction processes.

The Magmatic‐Hydrothermal System of the Three Sisters Volcanic Cluster, Oregon, Imaged From Field Gravity Measurements

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...
