A Rare Millisecond Pulsar with Cross-Pole Emission: Single-Pulse Insights from PSR J1857+0943
Shi-jun Dang, Ji-guang Lu, Peng Jiang +12
Studies of subpulse variability in millisecond pulsars (MSPs) offer important constraints on their emission physics. Using the high sensitivity of FAST, we present the first identi…

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…

An Extreme Radio Fluctuation of Pulsar B192910
Zhengli Wang, Shunshun Cao, Jiguang Lu +7
We report the detection of an extreme flux decrease accompanied by clear dispersion measure (DM) and rotation measure (RM) variations for pulsar B1929+10 during the 110-minute radi…
