Revisiting the Mysterious Origin of FRB 20121102A with Machine-learning Classification
Leah Ya-Ling Lin, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast radio bursts (FRBs) are millisecond-duration radio waves from the Universe. Even though more than 50 physical models have been proposed, the origin and physical mechanism of F…
Machine Learning Classification of Repeating FRBs from FRB121102
Bjorn Jasper R. Raquel, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast Radio Bursts (FRBs) are mysterious bursts in the millisecond timescale at radio wavelengths. Currently, there is little understanding about the classification of repeating FRB…
Classifying a frequently repeating fast radio burst, FRB 20201124A, with unsupervised machine learning
Bo Han Chen, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast radio bursts (FRBs) are astronomical transients with millisecond timescales. Although most of the FRBs are not observed to repeat, a few of them are detected to repeat more th…
Constraining the Hubble constant and its lower limit from the proper motion of extragalactic radio jets
Tiger Yu-Yang Hsiao, Tomotsugu Goto, Tetsuya Hashimoto +11
The Hubble constant () is a measurement to describe the expansion rate of the Universe in the current era. However, there is a discrepancy between the measurements fr…
On the relation between duration and energy of non-repeating fast radio bursts: census with the CHIME data
Seong Jin Kim, Tetsuya Hashimoto, Bo Han Chen +5
A correlation between the intrinsic energy and the burst duration of non-repeating fast radio bursts (FRBs) has been reported. If it exists, the correlation can be used to estimate…
Energy functions of fast radio bursts derived from the first CHIME/FRB catalogue
Tetsuya Hashimoto, Tomotsugu Goto, Bo Han Chen +9
Fast radio bursts (FRBs) are mysterious millisecond pulses in radio, most of which originate from distant galaxies. Revealing the origin of FRBs is becoming central in astronomy. T…
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 …
An Active Galactic Nucleus Recognition Model based on Deep Neural Network
Bo Han Chen, Tomotsugu Goto, Seong Jin Kim +21
To understand the cosmic accretion history of supermassive black holes, separating the radiation from active galactic nuclei (AGNs) and star-forming galaxies (SFGs) is critical. Ho…
