Renormalization group analysis of superradiant growth of self-interacting axion cloud
Hidetoshi Omiya, Takuya Takahashi, Takahiro Tanaka
There are strong interests in considering ultra-light scalar fields (especially axion) around a rapidly rotating black hole because of the possibility of observing gravitational wa…
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…
Gravitational wave echoes induced by a point mass plunging to a black hole
Norichika Sago, Takahiro Tanaka
Recently, the possibility of detecting gravitational wave echoes in the data stream subsequent to the binary black hole mergers observed by LIGO was suggested. Motivated by this su…
Resonant gravitational waves in dynamical Chern-Simons-axion gravity
Tomohiro Fujita, Ippei Obata, Takahiro Tanaka +1
In this paper, we consider dynamical Chern-Simons gravity with the identification of the scalar field coupled though the Pontryagin density with the axion dark matter, and we discu…
Parametrized test of parity-violating gravity using GWTC-1 events
Kei Yamada, Takahiro Tanaka
Parity-violating (PV) gravity has recently attracted interest in several aspects. One of them is the axion-graviton coupling to test the axion-dark matter model. Moreover, by exten…
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…
