A 'bang' in LIGO and Virgo detectors signals most massive gravitational wave source yet（图）
bang LIGO Virgo detectors signals massive gravitational source yet
2020/9/4
For all its vast emptiness, the universe is humming with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabri...
Prospects for early localization of gravitational-wave signals from compact binary coalescences with advanced detectors
Prospects early localization gravitational-wave signals compact binary coalescences advanced detectors
2012/2/21
A leading candidate source of detectable gravitational waves is the inspiral and merger of pairs of stellar-mass compact objects. The advanced LIGO and advanced Virgo detectors will allow scientists t...
Random matrix approach in search for weak signals immersed in background noise
Random matrix approach search signals immersed background noise
2011/10/17
We present new, original and alternative method for searching signals coded in noisy data. The method is based on the properties of random matrix eigenvalue spectra. First, we describe general ideas a...

We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point ...
On the Implications of Late Internal Dissipation for Shallow-Decay Afterglow Emission and Associated High-Energy Gamma-Ray Signals
gamma-rays burst general— gamma rays theory— radiation mechanisms non-thermal
2010/11/10
The origin of the shallow-decay emission during early X-ray afterglows has been an open issue since the launch of the Swift satellite. One of the appealing models is the late internal dissipation mode...
Unraveling Binary Evolution from Gravitational-Wave Signals and Source Statistics
Gravitational Waves Binary Evolution Neutron Stars Black Holes
2010/3/19
The next generation of ground-based gravitational-wave detectors are likely to observe gravitational waves from the coalescences of compact-objects binaries. We describe the state of the art for predi...
Analysis of Enhanced Velocity Signals Observed during Solar Flares
Sun:oscillations Sun:sunspots Sun:flares
2009/5/7
Solar flares are known to release a large amount of energy. It
is believed that the flares can excite velocity oscillations in active regions.
We report here the changes in velocity signals in three...
