Directional Limits on Persistent Gravitational Waves from Advanced LIGO’s First Observing Run

open access: yes, 2017
We employ gravitational-wave radiometry to map the stochastic gravitational wave backgroundexpected from a variety of contributing mechanisms and test the assumption of isotropy using datafrom the Advanced Laser Interferometer Gravitational Wave ...

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Gravitational Waves from Gravitational Collapse

open access: yesLiving Reviews in Relativity, 2011
Gravitational-wave emission from stellar collapse has been studied for nearly four decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat ...

Gravitational waves from known pulsars: results from the initial detector era

open access: yes, 2014
We present the results of searches for gravitational waves from a large selection of pulsars using data from the most recent science runs (S6, VSR2 and VSR4) of the initial generation of interferometric gravitational wave detectors LIGO (Laser ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Cylindrical gravitational waves

open access: yesClassical and Quantum Gravity, 1989
It is shown how the general cylindrical wave solution of Einstein's equations can be obtained from a matrix-valued generating function by adapting \textit{R. S. Ward}'s splitting construction [Gen. Relativ. Gravitation 15, 105-109 (1983; Zbl 0504.53022)].
