Statistical inference of fast radio burst environments using galaxy number density
Vignesh V. V. Rao, Tetsuya Hashimoto, Tomotsugu Goto +9
Fast radio bursts (FRBs) are bright, millisecond-duration radio transients of unknown origin. They are categorized as repeaters and non-repeaters, possibly indicating distinct prog…
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…
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…
Detailed Time Resolved Spectral and Temporal Investigations of SGR J1550-5418 Bursts Detected with Fermi/Gamma-ray Burst Monitor
Mustafa Demirer, Ersin GöÄüÅ, Yuki Kaneko +3
We have conducted a time-resolved spectral analysis of magnetar bursts originating from SGR J1550-5418. Our analysis utilizes a two-step methodology for temporal segmentation of th…
Decoding the cosmological baryonic fluctuations using localized fast radio bursts
Tzu-Yin Hsu, Tetsuya Hashimoto, Tsung-Ching Yang +7
Aims: The enigma of the missing baryons poses a prominent and unresolved problem in astronomy. Dispersion measures (DM) serve as a distinctive observable of fast radio bursts (FRBs…
Time-Frequency Correlation of Repeating Fast Radio Bursts: Correlated Aftershocks Tend to Exhibit Downward Frequency Drifts
Shotaro Yamasaki, Tomonori Totani
The production mechanism of fast radio bursts (FRBs)--mysterious, bright, millisecond-duration radio flashes from cosmological distances--remains unknown. Understanding potential c…
