Indication for Decreasing Dispersion Measure in the Population of Repeating Fast Radio Bursts and Connection to Young Supernova Remnant Expansion
Xiang-han Cui, Cheng-min Zhang, Di Li +9
Fast Radio Bursts (FRBs) are millisecond-duration, highly energetic radio transients of uncertain origin. Repeating FRBs provide an excellent population for investigating their nat…
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…
Multi-Faceted Emission Properties of PSR J2129+4119 Observed with FAST
Habtamu Menberu Tedila, Di Li, Pei Wang +10
We present a detailed single-pulse study of the long-period pulsar PSR J2129+4119 using high-sensitivity FAST observations. Despite locating well below the traditional death line,…
The magnetar model's energy crisis for a prolific repeating fast radio burst source
Jun-Shuo Zhang, Tian-Cong Wang, Pei Wang +61
Fast radio bursts (FRBs) are widely considered to originate from magnetars that power the explosion through releasing magnetic energy. Active repeating FRBs have been seen to produ…
Properties of the emission region in pulsars with opposite subpulse drift directions in different profile components
H. M. Tedila, R. Yuen, X. H. Han
We investigate properties of the emission region as revealed by drifting subpulses of opposite drift directions at different parts of a pulse profile by using the rotating carousel…
Unveiling the emission properties of three long-period pulsars using FAST
H. M. Tedila, D. Li, P. Wang +9
We detail the emission behaviors of three long-period pulsars detected using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) during the CRAFTS survey. Their rotati…
