Multi-optimization for thermal deformation of gravitational wave telescope based on CFRP characteristics

open access: yesScientific Reports
Gravitational wave telescope place extremely high demands on structural thermal deformation, making material selection a critical issue. Carbon fiber reinforced polymer (CFRP) is an ideal choice for the support structure of telescope due to its low ...

On-Ground Testing of Dual-Sided Release Mechanism of TianQin Test Mass Using a Pendulum

open access: yesSensors
The high-precision gravitational reference sensor, which hosts a heavy test mass (TM) surrounded by electrodes with a relatively large gap, is crucial in all high-sensitivity drag-free sensors.

The Impact of Angular Momentum Loss on the Outcomes of Binary Mass Transfer

open access: yesThe Astrophysical Journal, 2023
We use the rapid binary population synthesis code COMPAS to investigate commonly used prescriptions for the determination of mass transfer stability in close binaries and the orbital separations after stable mass transfer.

The Revo‐Evo Debate in the History and Philosophy of Science

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
The paper juxtaposes revolutionary and evolutionary positions in epistemology in general as well as the history of science. While it deems the evolutionary arguments more persuasive, it also stresses the dependence of our assessment of change on the language we choose to describe the theories and positions under consideration.

Gravitational Wave Astronomy [PDF]

open access: yes, 1997
Astronomers rely on a multiplicity of observational perspectives in order to infer the nature of the Universe. Progress in astronomy has historically been associated with new or improved observational perspectives. Gravitational wave detectors now under construction will provide us with a perspective on the Universe fundamentally different from any we ...

Research on High-Stability Composite Control Methods for Telescope Pointing Systems under Multiple Disturbances

open access: yesSensors
During the operation of space gravitational wave detectors, the constellation configuration formed by three satellites gradually deviates from the ideal 60° angle due to the periodic variations in orbits.

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

GW150914 and gravitational-wave astronomy [PDF]

open access: yesChinese Science Bulletin, 2016
On September 14, 2015, the first detection of gravitational waves at the advanced Laser Interferometer Gravitational- Wave Observatory (LIGO) detectors, in the United States, marked the beginning of “gravitational-wave astronomy”, that opens a new window looking into the violent sides of our Universe.

Missing Summer Westerly Jet Barotropic Governor Effect Explains Climate Models—Observation Discrepancies in the Indian Monsoon Trends

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The South Asian summer monsoon has exhibited a pronounced Northwest India‐Indo‐Gangetic Plains rainfall dipole since 1999, with northwest India experiencing a 24.6% increase, while rainfall in the Indo‐Gangetic Plain has decreased by 4.4%.

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

open access: yesEarth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
