Reprocessing of the Parkes 70-cm Survey and Discovery of a New Radio Pulsar in the Large Magellanic Cloud
Wenke Xia, Fronefield Crawford, Shinnosuke Hisano +4
We have reprocessed the data archived from the Parkes 70-cm pulsar (PKS70) survey with an expanded DM search range and an acceleration search. Our goal was to detect pulsars that m…

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…

Improving DM estimates using low-frequency scattering-broadening estimates
Jaikhomba Singha, Bhal Chandra Joshi, M. A. Krishnakumar +28
A pulsar's pulse profile gets broadened at low frequencies due to dispersion along the line of sight or due to multi-path propagation. The dynamic nature of the interstellar medium…
