Environmental Effects in Stellar Mass Gravitational-wave Sources. I. Expected Fraction of Signals with Significant Dephasing in the Dynamical and Active Galactic Nucleus Channels

The Astrophysical Journal
We present the first overview of the expected quantity of signals that will showcase significant gravitational-wave phase shifts caused by astrophysical environments, considering the upcoming A+ and A# LIGO/Virgo/KAGRA, Cosmic Explorer, and Einstein ...

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

The pregalactic cosmic gravitational wave background

, 1989
An outline is given that estimates the expected gravitational wave background, based on plausible pregalactic sources. Some cosmologically significant limits can be put on incoherent gravitational wave background arising from pregalactic cosmic evolution.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Redistributive effects of unsteady flow regimes downstream of reservoirs

River, EarlyView.
Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

A Methodological Framework to Study Change in Team Cognition Under the Dynamical Hypothesis

Topics in Cognitive Science, EarlyView., 2023
Abstract The dynamical hypothesis claims that cognitive systems, such as teams, are dynamical systems (i.e., an interdependent collection of individuals and their technology that change together over time). Following this hypothesis, team researchers have adopted dynamical approaches to better understand the team cognitive processes and states that ...

Sources of gravitational waves

, 1989
Sources of low frequency gravitational radiation are reviewed from an astrophysical point of view. Cosmological sources include the formation of massive black holes in galactic nuclei, the capture by such holes of neutron stars, the coalescence of ...

Taming the Plunge: A Circularization Trap of Supermassive Black Hole Binaries

The Astrophysical Journal
We investigate the orbital eccentricity evolution of supermassive black hole binaries (SMBHBs; 10 ^4 –10 ^7 M _⊙ ) within galactic environments. Merger timescales depend on eccentricity when gravitational-wave (GW) emission dominates.

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.
