Assessing astrophysical foreground subtraction in DECIGO using compact binary populations inferred from the first part of the LIGO-Virgo-KAGRA's fourth observation run
Takahiro S. Yamamoto
Detecting the stochastic gravitational wave background (SGWB) from our Universe under the inflationary era is one of the primary scientific objectives of DECi-hertz Interferometer…
Hybrid algorithm combining matched filtering and convolutional neural networks for searching gravitational waves from binary black hole mergers
Takahiro S. Yamamoto, Kipp Cannon, Hayato Motohashi +1
Efficient searches for gravitational waves from compact binary coalescence are crucial for gravitational wave observations. We present a proof-of-concept for a method that utilizes…
Multi-band observation of lensed gravitational waves as a probe of small-mass dark matter halos
Katsuya T. Abe, Shun Arai, Ryoto Inui +3
The gravitational lensing effect of gravitational waves (GWs) has been extensively discussed as a probe of small-mass dark matter halos, which can provide missing information about…
Applying the Viterbi Algorithm to Planetary-Mass Black Hole Searches
George Alestas, Gonzalo Morras, Takahiro S. Yamamoto +3
The search for subsolar mass primordial black holes (PBHs) poses a challenging problem due to the low signal-to-noise ratio, extended signal duration, and computational cost demand…
Prospects of detection of subsolar mass primordial black hole and white dwarf binary mergers
Takahiro S. Yamamoto, Ryoto Inui, Yuichiro Tada +1
The subsolar mass primordial black hole (PBH) attracts attention as robust evidence of its primordial origin against the astrophysical black hole. Not only with themselves, PBHs ca…
