Improved sensitivity of interferometric gravitational wave detectors to ultralight vector dark matter from the finite light-traveling time
Soichiro Morisaki, Tomohiro Fujita, Yuta Michimura +2
Recently several studies have pointed out that gravitational-wave detectors are sensitive to ultralight vector dark matter and can improve the current best constraints given by the…
Statistically-Anisotropic Tensor Bispectrum from Inflation
Takashi Hiramatsu, Kai Murai, Ippei Obata +1
We develop a possibility of generating tensor non-Gaussianity in a kind of anisotropic inflation, where a gauge field is kinetically coupled to a spectator scalar field. Owi…
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…
Ultralight vector dark matter search with auxiliary length channels of gravitational wave detectors
Yuta Michimura, Tomohiro Fujita, Soichiro Morisaki +2
Recently, a considerable amount of attention has been given to the search for ultralight dark matter by measuring the oscillating length changes in the arm cavities of gravitationa…
