Gravitational-wave EM Counterpart Korean Observatory (GECKO)

Proceedings of the International Astronomical Union, 2020
AbstractIdentification of the electromagnetic-wave (EM) counterparts of gravitational-wave (GW) sources can significantly broaden the research scope of GW astronomy, by pinpointing the exact locations of GW events and their environments, and using GW sources as standard sirens for cosmology.

Precessing Black Hole Binaries and Their Gravitational Radiation

Universe, 2018
The first and second observational runs of Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) have marked the first direct detections of gravitational waves, either from black hole binaries or, in one case, from coalescing neutron stars.

Primordial black holes and secondary gravitational waves from natural inflation

Nuclear Physics B, 2021
The production of primordial black hole (PBH) dark matter (DM) and the generation of scalar induced secondary gravitational waves by using the enhancement mechanism with a peak function in the non-canonical kinetic term in natural inflation is discussed.

Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Sensitivity curves for spaceborne gravitational wave interferometers [PDF]

, 2000
To determine whether particular sources of gravitational radiation will be detectable by a specific gravitational wave detector, it is necessary to know the sensitivity limits of the instrument.

Pattern of Inner‐Core Differential Rotation From Long‐Term Earthquake Sequences and USArray Network

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract How the differential rotation of the Earth's inner core (IC) has changed over time provides insights into the dynamics of the Earth's interior. Analyses of repeating earthquakes (doublets) have yielded different models. Here we present an event‐based investigation using individual events from long‐term earthquake sequences, which improves ...

A First Targeted Search for Gravitational-Wave Bursts from Core-Collapse Supernovae in Data of First-Generation Laser Interferometer Detectors [PDF]

, 2016
We present results from a search for gravitational-wave bursts coincident with two core-collapse supernovae observed optically in 2007 and 2011. We employ data from the Laser Interferometer Gravitational-wave Observatory (LIGO), the Virgo gravitational ...

Electromagnetic Evidence that SSS17a is the Result of a Binary Neutron Star Merger

, 2017
11 hours after the detection of gravitational wave source GW170817 by the Laser Interferometer Gravitational-Wave Observatory and Virgo Interferometers, an associated optical transient SSS17a was discovered in the galaxy NGC 4993. While the gravitational

Gravitational Waves from Phase Transition of Accreting Neutron Stars [PDF]

, 1997
We propose that when neutron stars in low-mass X-ray binaries accrete sufficient mass and become millisecond pulsars, the interiors of these stars may undergo phase transitions, which excite stellar radial oscillations.

Baseline Climatology of Gravity Waves From ∼30 to ∼70 km Established With Lidar Observations Over a Decade at McMurdo (77.84°S, 166.67°E), Antarctica: Implications for Vertical Wave Evolution

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Lidar observations of atmospheric gravity waves (GWs) have been made spanning 14 years above McMurdo Station, Antarctica. Using these extensive observations and interleaved data processing techniques which enable bias‐free/noise‐floor‐free estimation of GW parameters, this study forms seasonal baselines for GW potential energy densities (Epm ...
