Probing warm and mixed dark matter models using lensing shift power spectrum
Kaiki Taro Inoue, Takumi Shinohara, Teruaki Suyama +1
We argue that the lensing power spectrum of astrometric shift (lensing shift power spectrum) is a powerful tool of the clustering property of dark matter on subgalactic scales. Fir…
New Consistency Relations between Averages and Variances of Weakly Lensed Signals of Gravitational Waves
Morifumi Mizuno, Teruaki Suyama, Ryuichi Takahashi
The lensing of gravitational waves (GWs) occurs when GWs experience local gravitational potential. In the weak lensing regime, it has been reported that a simple consistency relati…
Extra-tensor-induced origin for the PTA signal: No primordial black hole production
Mohammad Ali Gorji, Misao Sasaki, Teruaki Suyama
Recently, pulsar timing array (PTA) collaborations announced evidence for an isotropic stochastic gravitational wave (GW) background. The origin of the PTA signal can be astrophysi…
Supermassive primordial black holes: a view from clustering of quasars at
Takumi Shinohara, Wanqiu He, Yoshiki Matsuoka +3
We investigate a scenario where primordial black holes (PBHs) can be the progenitors of supermassive black holes (SMBHs) observed at . To this end, we carried out clusterin…
Probing the solar interior with lensed gravitational waves from known pulsars
Ryuichi Takahashi, Soichiro Morisaki, Teruaki Suyama
When gravitational waves (GWs) from a spinning neutron star arrive from behind the Sun, they are subjected to gravitational lensing that imprints a frequency-dependent modulation o…
Upper limit on scalar field dark matter from LIGO-Virgo third observation run
Koki Fukusumi, Soichiro Morisaki, Teruaki Suyama
If dark matter is a light scalar field weakly interacting with elementary particles, such a field induces oscillations of the physical constants, which results in time-varying forc…
