Scintillation of the first-known pulsar planetary system
J. M. Yao, L. Zhang, A. Wolszczan +8
We present a scintillation study of the first-known pulsar planetary system, PSR~B1257+12, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). A total of 31 obs…
Variability, polarimetry, and timing properties of single pulses from PSR J2222-0137 using FAST
X. L. Miao, W. W. Zhu, M. Kramer +14
In our work, we analyse single pulses from the recycled pulsar PSR J22220137 in one of its scintillation maxima observed by the Five-hundred-meter Aperture Spher…
Arecibo and FAST Timing Follow-up of twelve Millisecond Pulsars Discovered in Commensal Radio Astronomy FAST Survey
C. C. Miao, W. W. Zhu, D. Li +46
We report the phase-connected timing ephemeris, polarization pulse profiles, Faraday rotation measurements, and Rotating-Vector-Model (RVM) fitting results of twelve millisecond pu…
Magnetic Field Reversal around an Active Fast Radio Burst
S. Dai, Y. Feng, Y. P. Yang +22
The environment of actively repeating fast radio bursts (FRBs) has been shown to be complex and varying. The recently localized FRB 20190520B is extremely active, has the largest c…
Unusual Emission Variations Near the Eclipse of A Black Widow PSR J17200533
S. Q. Wang, J. B. Wang, N. Wang +15
We report on an {unusually} bright observation of PSR J17200533 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The pulsar is in a black widow system tha…
A repeating fast radio burst associated with a persistent radio source
C. -H. Niu, K. Aggarwal, D. Li +32
The dispersive sweep of fast radio bursts (FRBs) has been used to probe the ionized baryon content of the intergalactic medium, which is assumed to dominate the total extragalactic…
Periodic and Phase-locked Modulation in PSR B1929+10 Observed with FAST
F. F. Kou, W. M. Yan, B. Peng +17
We present a detailed single-pulse analysis for PSR B1929+10 based on observations with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The main pulse and interpu…
