Relativistic effects of PSR~J1856--0039 double neutron star system in a 2.36-hour compact orbit
Z. L. Yang, J. L. Han, W. Q. Su +11
Compact double neutron star (DNS) systems are unique laboratories for testing gravitational theories and studying DNS mergers. Here we report the properties of a new DNS system, PS…
FAST Pulsar Database III. Snapshots of nulling, mode-changing and subpulse modulation of 374 pulsars
Yi Yan, J. L. Han, J. Xu +8
Based on sensitive L-band (1.0 to 1.5 GHz) observations of pulsars using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we analyzed single-pulse sequences from F…
FAST Pulsar Database IV. Spike subpulses and quasi-periodic subpulses of 25 pulsars observed by FAST
Tao Wang, N. N. Cai, J. L. Han +6
Fine structures of individual pulses can be detected when observations are conducted with a high time resolution and a great sensitivity. We examined pulsar data observed by the Fi…
The FAST Galactic Plane Pulsar Snapshot Survey. IX. Timing Three Binary Pulsars with Wide Orbits and Low Orbital Eccentricities
Z. L. Yang, J. L. Han, W. Q. Su +11
Current pulsar timing models face challenges when applied to binary pulsars with wide orbits and low orbital eccentricities. The conventional \texttt{DD} model accurately character…
FAST Pulsar Database: II. Scattering profiles of 149 Pulsars
W. C. Jing, J. L. Han, C. Wang +10
The turbulent ionized interstellar medium diffracts radio waves and makes them propagate in multiple paths. The pulse-broadening observed at low frequencies results from the scatte…
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…
Polarized radio emission of RRAT J1854+0306
Qi Guo, Minzhi Kong, P. F. Wang +2
Polarized radio emission of RRAT J1854+0306 is investigated with single pulses using Five-hundred-meter-Aperture Spherical Telescope. Its emission is characterized by nulls, narrow…
The FAST Galactic Plane Pulsar Snapshot Survey -- V. PSR J1901+0658 in a double neutron star system
W. Q. Su, J. L. Han, Z. L. Yang +13
Double neutron star (DNS) systems offer excellent opportunities to test gravity theories. We report the timing results of PSR J1901+0658, the first pulsar discovered in the FAST Ga…
Dwarf pulses of 10 pulsars detected by FAST
Yi Yan, J. L. Han, D. J. Zhou +5
How pulsars radiate is a long-standing problem. Detailed polarization measurements of individual pulses shed light on currently unknown emission processes. Recently, based on super…
The FAST Galactic Plane Pulsar Snapshot survey: IV. Discovery of five fast radio bursts
D. J. Zhou, J. L. Han, W. C. Jing +8
We report five new fast radio bursts (FRBs) discovered from the Galactic Plane Pulsar Snapshot (GPPS) survey by the Five-hundred-meter Aperture Spherical radio Telescope (FAST): FR…
The FAST Galactic Plane Pulsar Snapshot Survey: III. Timing results of 30 FAST-GPPS discovered pulsars
W. Q. Su, J. L. Han, P. F. Wang +14
Timing observations are crucial for determining the basic parameters of newly discovered pulsars. Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) with the L-…
Jiamusi pulsar observations: IV. The core-weak pattern of PSR B0329+54
Tao Wang, J. L. Han, C. Wang +2
The bright pulsar PSR B0329+54 was previously known for many years to have two emission modes. Sensitive observations of individual pulses reveal that the central component of puls…
A fast radio burst source at a complex magnetised site in a barred galaxy
H. Xu, J. R. Niu, P. Chen +71
Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio bursts. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but…
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…
