Tiny-Scale Properties within the Interstellar Medium towards PSR J16444559: I. Observational Evidence of Turbulence-induced Tiny Scale Atomic Structures
Mengting Liu, Di Li, J. R. Dawson +21
We investigated HI absorption toward a single pulsar, PSR J16444559, and its variability over timescales from days to years, using Murriyang, CSIRO's Parkes Radio Telescope. Our…
Reciprocating Magnetic Fields in the Pulsar Wind Observed from the Black Widow Pulsar J1720-0534
Chen-Chen Miao, Victoria Blackmon, Wei-Wei Zhu +41
We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M. We obtain t…
Galactic Interstellar Scintillation Observed from Four Globular Cluster Pulsars by FAST
Dandan Zhang, Zhenzhao Tao, Mao Yuan +9
We report detections of scintillation arcs for pulsars in globular clusters M5, M13 and M15 for the first time using the Five-hundred-meter Aperture Spherical radio Telescope (FAST…
Circular Polarization in two Active Repeating Fast Radio Bursts
Yi Feng, Yong-Kun Zhang, Di Li +5
Fast radio bursts (FRBs) are bright millisecond radio bursts at cosmological distances. Only a small fraction of FRBs apparently repeat. Polarization, a fundamental property of ele…
Interstellar scintillation and polarization of PSR B0656+14 in the Monogem Ring
Jumei Yao, William A. Coles, Richard N. Manchester +8
High sensitivity interstellar scintillation and polarization observations of PSR~B0656+14 made at three epochs over a year using the Five-hundred-meter Aperture Spherical radio Tel…
Simulating high-time resolution radio-telescope observations
Rui Luo, George Hobbs, Suk Yee Yong +10
We describe a new software package for simulating channelised, high-time resolution data streams from radio telescopes. The software simulates data from the telescope and observing…
Categorize Radio Interference using component and temporal analysis
Mao Yuan, Weiwei Zhu, Haiyan Zhang +12
Radio frequency interference (RFI) is a significant challenge faced by today's radio astronomers. While most past efforts were devoted to cleaning the RFI from the data, we develop…
A GPU based single-pulse search pipeline (GSP) with database and its application to the commensal radio astronomy FAST survey (CRAFTS)
Shanping You, Pei Wang, Xuhong Yu +8
We developed a GPU based single-pulse search pipeline (GSP) with candidate-archiving database. Largely based upon the infrastructure of Open source pulsar search and analysis toolk…
FAST discovery of an extremely radio-faint millisecond pulsar from the Fermi-LAT unassociated source 3FGL J0318.1+0252
Pei Wang, Di Li, Colin J. Clark +23
High sensitivity radio searches of unassociated -ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Tel…
Revisiting Pulsar Velocities Using Gaia Data Release 2
Meng Yang, Shi Dai, Di Li +3
Precise measurements of neutron star (NS) velocities provide critical clues to the supernova physics and evolution of binary systems. Based on Gaia Data Release 2 (DR2), we selecte…
A single pulse study of PSR J1022+1001
Yi Feng, George Hobbs, Di Li +11
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we have recorded 10^5 single pulses from PSR J1022+1001. We studied the polarization properties, their energ…
Wideband Monitoring Observations of PSR J1803-3002A in the Globular Cluster NGC 6522
Lei Zhang, Richard N. Manchester, Andrew D. Cameron +10
We report the first wideband monitoring observations of PSR J1803-3002A, a relatively bright millisecond pulsar in the globular cluster NGC 6522 with a spin period of 7.1 ms and no…
On the Circular Polarisation of Repeating Fast Radio Bursts
Shi Dai, Jiguang Lu, Chen Wang +9
Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here…
The two emission states of PSR B1534+12
S. Q. Wang, G. Hobbs, J. B. Wang +10
We have observed PSR~B1534+12 (J1537+1155), a pulsar with a neutron star companion, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We found that this pulsa…
Applying saliency-map analysis in searches for pulsars and fast radio bursts
C. Zhang, C. Wang, G. Hobbs +9
To investigate the use of saliency-map analysis to aid in searches for transient signals, such as fast radio bursts and individual pulses from radio pulsars. We aim to demonstrate…
Parkes transient events: I. Database of single pulses, initial results and missing FRBs
S. -B. Zhang, G. Hobbs, C. J. Russell +16
A large number of observations from the Parkes 64\,m-diameter radio telescope, recorded with high time resolution, are publicly available. We have re-processed all of the observati…
Probing the emission states of PSR J1107-5907
Jingbo Wang, George Hobbs, Matthew Kerr +14
The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
