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…

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…

Constraining the Hubble constant with scattering in host galaxies of fast radio bursts

Tsung-Ching Yang, Tetsuya Hashimoto, Tzu-Yin Hsu +5

Measuring the Hubble constant (H) is one of the most important missions in astronomy. Nevertheless, recent studies exhibit differences between the employed methods. Fast radio…

ALMA reveals spatially-resolved properties of molecular gas in the host galaxy of FRB 20191001A at z = 0.2340

Itsuki Yamanaka, Bunyo Hatsukade, Fumi Egusa +5

We report the detection of the CO(2-1) emission line with a spatial resolution of 0.9 arcsec () from the host galaxy of the fast radio burst (FRB), FRB 20191001A…

Upper limits on transmitter rate of extragalactic civilizations placed by Breakthrough Listen observations

Yuri Uno, Tetsuya Hashimoto, Tomotsugu Goto +3

The Search for Extra-Terrestrial Intelligence (SETI) has been conducted for over sixty years, yet no technosignatures have been identified. Previous studies have focused on stars i…

The molecular gas kinematics in the host galaxy of non-repeating FRB 180924B

Tzu-Yin Hsu, Tetsuya Hashimoto, Bunyo Hatsukade +5

Fast radio bursts (FRBs) are millisecond-duration transients with large dispersion measures. The origin of FRBs is still mysterious. One of the methods to comprehend FRB origin is…

Diverse Properties of Molecular Gas in the Host Galaxies of Fast Radio Bursts

Bunyo Hatsukade, Tetsuya Hashimoto, Yuu Niino +1

We report the properties of molecular gas in a sample of six host galaxies of fast radio bursts (FRBs) obtained from CO observations with the Atacama Large Millimeter/submillimeter…
