Training Process of Unsupervised Learning Architecture for Gravity Spy Dataset
Yusuke Sakai, Yousuke Itoh, Piljong Jung +11
Transient noise appearing in the data from gravitational-wave detectors frequently causes problems, such as instability of the detectors and overlapping or mimicking gravitational-…
Deep learning for intermittent gravitational wave signals
Takahiro S. Yamamoto, Sachiko Kuroyanagi, Guo-Chin Liu
The ensemble of unresolved compact binary coalescences is a promising source of the stochastic gravitational wave (GW) background. For stellar-mass black hole binaries, the astroph…
Assessing the impact of non-Gaussian noise on convolutional neural networks that search for continuous gravitational waves
Takahiro S. Yamamoto, Andrew L. Miller, Magdalena Sieniawska +1
We present a convolutional neural network that is capable of searching for continuous gravitational waves, quasi-monochromatic, persistent signals arising from asymmetrically rotat…
Unsupervised Learning Architecture for Classifying the Transient Noise of Interferometric Gravitational-wave Detectors
Yusuke Sakai, Yousuke Itoh, Piljong Jung +11
In the data obtained by laser interferometric gravitational wave detectors, transient noise with non-stationary and non-Gaussian features occurs at a high rate. This often results…
Use of Excess Power Method and Convolutional Neural Network in All-Sky Search for Continuous Gravitational Waves
Takahiro S. Yamamoto, Takahiro Tanaka
The signal of continuous gravitational waves has a longer duration than the observation period. Even if the waveform in the source frame is monochromatic, we will observe the wavef…
Use of conditional variational auto encoder to analyze ringdown gravitational waves
Takahiro S. Yamamoto, Takahiro Tanaka
Recently, several deep learning methods are proposed for the gravitational wave data analysis. One is conditional variational auto encoder (CVAE), proposed by Gabbard et al. [1]. W…
Design and experimental demonstration of a laser modulation system for future gravitational-wave detectors
Kohei Yamamoto, Keiko Kokeyama, Yuta Michimura +12
Detuning the signal-recycling cavity length from a cavity resonance significantly improves the quantum noise beyond the standard quantum limit, while there is no km-scale gravitati…
Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
Comparison of various methods to extract ringdown frequency from gravitational wave data
Hiroyuki Nakano, Tatsuya Narikawa, Ken-ichi Oohara +7
The ringdown part of gravitational waves in the final stage of merger of compact objects tells us the nature of strong gravity which can be used for testing the theories of gravity…
Improving the absolute accuracy of the gravitational wave detectors by combining the photon pressure and gravity field calibrators
Yuki Inoue, Sadakazu Haino, Nobuyuki Kanda +5
The absolute accuracy of the estimated parameters of gravitational wave sources will be fundamentally limited by the calibration uncertainties of the detectors in upcoming observat…
Black Holes, Dark Matter Spikes, and Constraints on Simplified Models with -Channel Mediators
Pearl Sandick, Kuver Sinha, Takahiro Yamamoto
The density spike of dark matter (DM) in the subparsec region near the supermassive black hole at the Galactic Center can provide potentially observable gamma-ray signals coming fr…
Gamma-ray Signals from Dark Matter Annihilation Via Charged Mediators
Jason Kumar, Pearl Sandick, Fei Teng +1
We consider a simplified model in which Majorana fermion dark matter annihilates to charged fermions through exchange of charged mediators. We consider the gamma-ray signals arisin…
MSSM dark matter and a light slepton sector: The Incredible Bulk
Keita Fukushima, Chris Kelso, Jason Kumar +2
Recent experimental results from the LHC have placed strong constraints on the masses of QCD-charged superpartners. The MSSM parameter space is also constrained by the measurement…
