A Comprehensive Study of Binary Compact Objects as Gravitational Wave Sources: Evolutionary Channels, Rates, and Physical Properties [PDF]
, 2001 A new generation of ground-based interferometric detectors for gravitational waves is currently under construction or has entered the commissioning phase (Laser Interferometer Gravitational-wave Observatory [LIGO], VIRGO, GEO600, TAMA300). The purpose of

, 2011 We show that the regularity of the gravitational metric tensor in spher- ically symmetric spacetimes cannot be lifted from C0,1 to C1,1 within the class of C1,1 coordinate transformations in a neighborhood of a point of shock wave inter- action in ...

Strongly Lensed Supermassive Black Hole Binaries as Nanohertz Gravitational-wave Sources
The Astrophysical Journal, 2023 Supermassive black hole binary systems (SMBHBs) should be the most powerful sources of gravitational waves (GWs) in the universe. Once pulsar timing arrays (PTAs) detect the stochastic GW background from their cosmic merger history, searching for ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Gravitational waves: Sources, detectors and searches [PDF]
Progress in Particle and Nuclear Physics, 2013 Gravitational wave science should transform in this decade from a study of what has not been seen to a full-fledged field of astronomy in which detected signals reveal the nature of cataclysmic events and exotic objects. The LIGO Scientific Collaboration and Virgo Collaboration have recently completed joint data runs of unprecedented sensitivities to ...

Single sources in the low-frequency gravitational wave sky: properties and time to detection by pulsar timing arrays [PDF]
, 2017 We calculate the properties, occurrence rates and detection prospects of individually resolvable 'single sources' in the low frequency gravitational wave (GW) spectrum.
