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…

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…

Supermassive Binary Black Hole Evolution can be traced by a small SKA Pulsar Timing Array

Yi Feng, Di Li, Zheng Zheng +1

Supermassive black holes are commonly found in the center of galaxies and evolve with their hosts. The supermassive binary black holes (SMBBH) are thus expected to exist in close g…

A Fast Radio Burst discovered in FAST drift scan survey

Weiwei Zhu, Di Li, Rui Luo +67

We report the discovery of a highly dispersed fast radio burst, FRB~181123, from an analysis of 1500~hr of drift-scan survey data taken using the Five-hundred-meter Aperture…

Machine Learning for Nanohertz Gravitational Wave Detection and Parameter Estimation with Pulsar Timing Array

MengNi Chen, Yuanhong Zhong, Yi Feng +2

Studies have shown that the use of pulsar timing arrays (PTAs) is among the approaches with the highest potential to detect very low-frequency gravitational waves in the near futur…
