Cross-validation of six dispersion measure estimation methods for FRB 20240114A

Tonglun Wang, Songbo Zhang, Yuanchuan Zou +11

Fast Radio Bursts (FRBs) are important cosmological probes, but their applications depend critically on accurate dispersion measure (DM) determinations. We present a systematic com…

Search for an isotropic gravitational-wave background with the Parkes Pulsar Timing Array

Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +26

Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common t…

Frequency-dependent polarization of repeating fast radio bursts-implications for their origin

Yi Feng, Di Li, Yuan-Pei Yang +23

The polarization of fast radio bursts (FRBs), bright astronomical transients, contains crucial information about their environments. We report polarization measurements of five rep…

Searching for radio pulsation from SGR 1935+2154 with the Parkes Ultra-Wideband Low receiver

Zhenfan Tang, Songbo Zhang, Shi Dai +2

Magnetars have been proposed to be the origin of FRBs soon after its initial discovery. The detection of the first Galactic FRB 20200428 from SGR 1935+2154 has made this hypothesis…

On the Circular Polarisation of Repeating Fast Radio Bursts

Shi Dai, Jiguang Lu, Chen Wang +9

Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here…

Probing the emission states of PSR J1107-5907

Jingbo Wang, George Hobbs, Matthew Kerr +14

The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
