All-sky search of NAUTILUS data

, 2008
A search for periodic gravitational-wave signals from isolated neutron stars in the NAUTILUS detector data is presented. We have analyzed half a year of data over the frequency band $$ Hz, the spindown range $$ Hz/s and over the entire sky.

Simulation and Experimental Study on Frequency Noise of Fabry-Pérot Cavity-Stabilized Laser for Space-Borne Gravitational Wave Detection

IEEE Photonics Journal
In response to the specific requirements of space-borne gravitational wave detectors (SGWD) for laser frequency stability, this work systematically analyzes and investigates the frequency noise of Fabry-Pérot (FP) cavity-based ultra-stable lasers (

Self-forced gravitational waveforms for Extreme and Intermediate mass ratio inspirals

, 2012
We present the first orbit-integrated self force effects on the gravitational waveform for an I(E)MRI source. We consider the quasi-circular motion of a particle in the spacetime of a Schwarzschild black hole and study the dependence of the dephasing of ...

Gravitational Waves from Supermassive Black Hole Coalescence in a Hierarchical Galaxy Formation Model

, 2004
We investigate the expected gravitational wave emission from coalescing supermassive black hole (SMBH) binaries resulting from mergers of their host galaxies. When galaxies merge, the SMBHs in the host galaxies sink to the center of the new merged galaxy

Reducing the number of templates for aligned-spin compact binary coalescence gravitational wave searches using metric-agnostic template nudging

, 2018
Efficient multi-dimensional template placement is crucial in computationally intensive matched-filtering searches for Gravitational Waves (GWs). Here, we implement the Neighboring Cell Algorithm (NCA) to improve the detection volume of an existing ...

An Improved Search Method for Gravitational Ringing of Black Holes

, 2004
A black hole has characteristic quasi-normal modes that will be excited when it is formed or when the geometry is perturbed. The state of a black hole when the quasi-normal modes are excited is called the gravitational ringing, and detections of it will ...
