Abstract

We present recent advancements in the Japanese space-based gravitational-wave detectors DECIGO (Deci-Hertz Gravitational-wave Observatory) and B-DECIGO, focusing on refined sensitivity estimation, binary black hole localization with B-DECIGO and DECIGO's capability to measure the early universe's reheating temperature. Through simulations and experiments involving back-linked interferometers, pre-stabilized lasers and optimized satellite orbits, we demonstrate key techniques that improve signal-to-noise ratios across a broad frequency range. Our work incorporates advanced parameter adjustments, including mirror geometry optimization and noise reduction techniques such as square completion and optical springs, leading to enhanced signal-to-noise ratios over a wide frequency range. These developments pave the way for B-DECIGO and DECIGO to explore high-redshift cosmology and early universe phenomena. [ABSTRACT FROM AUTHOR]
