Probing Variations in Earth's Ionosphere Using Pulsars

Yanqing Cai, Ziwei Wu, Weiwei Zhu +24

We present high cadence 10-minute rotation measure (RM) monitoring of PSR~J0814+7429 using the LOw-Frequency ARray, aiming to probe ionospheric variability along the pulsar line of…

No Strong Evidence for Plasma Lensing in FRB 20240114A

Jiarui Niu, Xiaohui Liu, Nan Xu +33

FRB 20240114A is an extremely active repeating fast radio burst for which plasma lensing has been proposed to explain its burst-rate variations, spectral evolution, and apparently…

Discovery of a 24-millisecond pulsar in a very long orbit with the Murchison Widefield Array

Chia Min Tan, N. D. Ramesh Bhat, Bradley W. Meyers +9

We report the discovery of PSR J01255854, a pulsar with a spin period of 24 ms and a dispersion measure of 11.66 pc cm in the ongoing Southern-sky MWA Rapid Two-metre (SMAR…

Pulsar scintillation studies with LOFAR III. Annual variations in PSR~J08147429

Yanqing Cai, Ziwei Wu, Weiwei Zhu +27

The interstellar scintillation observed in radio pulsars arises from interference between electromagnetic waves scattered by electron density fluctuations in the turbulent interste…

The double neutron star PSR J1946+2052 I. Masses and tests of general relativity

Lingqi Meng, Paulo C. C. Freire, Kevin Stovall +28

We conducted high-precision timing of PSR J1946+2052 to determine the masses of the two neutron stars in the system, test general relativity (GR) and assessed the system's potentia…

Single-pulse-based interstellar scintillation studies of RRATs

Zi-wei Wu, Wei-wei Zhu, Zi-yao Fang +16

The nature of irregularly spaced pulses of rotating radio transients (RRATs) complicates interstellar scintillation studies. In this letter, we report the primary scintillation par…

A 44-minute periodic radio transient in a supernova remnant

Di Li, Mao Yuan, Lin Wu +45

Long-period radio transients (LPTs) are a newly discovered class of radio emitters with periods ranging from minutes to hours. The astrophysical nature remains undetermined, partic…

Sudden polarization angle jumps of the repeating fast radio burst FRB 20201124A

J. R. Niu, W. Y. Wang, J. C. Jiang +41

We report the first detection of polarization angle (PA) orthogonal jumps, a phenomenon previously only observed from radio pulsars, from a fast radio burst (FRB) source FRB 202011…
