Upper limits on Einstein's weak equivalence principle placed by uncertainties of dispersion measures of fast radio bursts
Tetsuya Hashimoto, Tomotsugu Goto, Daryl Joe D. Santos +7
Fast radio bursts (FRBs) are astronomical transients with millisecond timescales occurring at cosmological distances. The observed time lag between different energies of each FRB i…
Constraining violations of the Weak Equivalence Principle Using CHIME FRBs
Kaustubha Sen, Tetsuya Hashimoto, Tomotsugu Goto +7
Einstein's General Relativity (GR) is the basis of modern astronomy and astrophysics. Testing the validity of basic assumptions of GR is important. In this work, we test a possible…
Uncloaking hidden repeating fast radio bursts with unsupervised machine learning
Bo Han Chen, Tetsuya Hashimoto, Tomotsugu Goto +5
The origins of fast radio bursts (FRBs), astronomical transients with millisecond timescales, remain unknown. One of the difficulties stems from the possibility that observed FRBs…
Environmental Effects on AGN activity via Extinction-free Mid-Infrared Census
Daryl Joe D. Santos, Tomotsugu Goto, Seong Jin Kim +20
How does the environment affect active galactic nucleus (AGN) activity? We investigated this question in an extinction-free way, by selecting 1120 infrared galaxies in the …
A Dyson Sphere around a black hole
Tiger Yu-Yang Hsiao, Tomotsugu Goto, Tetsuya Hashimoto +8
The search for extraterrestrial intelligence (SETI) has been conducted for nearly 60 years. A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative…
Revealing the cosmic reionisation history with fast radio bursts in the era of Square Kilometre Array
Tetsuya Hashimoto, Tomotsugu Goto, Ting-Yi Lu +7
Revealing the cosmic reionisation history is at the frontier of extragalactic astronomy. The power spectrum of the cosmic microwave background (CMB) polarisation can be used to con…
