Single-Pulse Correlations in PSR B0329+54: Implications for Radio Emission Zones
Shyam S. Sharma, Tetsuya Hashimoto, Tomotsugu Goto +3
Individual radio pulses from a pulsar are directly linked to the underlying emission processes and the associated magnetic field geometry within its magnetosphere. Thus, single-pul…
Unveiling Hidden Clustering: An Unsupervised Machine Learning Study of Repeating FRB 20220912A
An-Chieh Hsu, Tetsuya Hashimoto, Tomotsugu Goto +2
Fast Radio Bursts (FRBs) are millisecond-duration radio transients of extragalactic origin. Classifying repeating FRBs is essential for understanding their emission mechanisms, but…
Irregularity in Active Fast Radio Burst Repeaters and Magnetar Periodic Radio Pulses: Time, Energy, and Frequency Analyses
Ellen C. C. Lin, Shotaro Yamasaki, Tomotsugu Goto +1
Fast Radio Bursts (FRBs) are millisecond-duration radio pulses with largely unknown origins, with a subset exhibiting repeating behavior. Magnetars highly magnetized neutron stars…
Machine learning classification of baseband data of CHIME FRBs
Mohanraj Madheshwaran, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast Radio Bursts (FRBs) are bright millisecond radio pulses. Their origin is still unknown in the field of astronomy. A notable distinction among FRBs is that some sources repeat,…
No Metallicity Preference in Fast Radio Burst Host Galaxies
Shotaro Yamasaki, Tetsuya Hashimoto, Haruka Kusakabe +1
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients of unknown origin, and studying their host galaxies could offer clues to constrain progenitor model…
Do they repeat? Monitoring 36 non-repeating FRBs with FAST
Yuri Uno, Tetsuya Hashimoto, Tomotsugu Goto +12
The origin of fast radio bursts (FRBs), highly energetic, millisecond-duration radio pulses originating from beyond our galaxy, remains unknown. Observationally, FRBs are classifie…
