Towards DM-free search for Fast Radio Bursts with Machine Learning -- I. An implementation on multibeam data
Yao Chen, Rui Luo, Chen Wang +13
Searching for fleeting radio transients like fast radio bursts (FRBs) with wide-field radio telescopes has become a common challenge in data-intensive science. Conventional algorit…
Supernova Classification using the Recurrent Neural Network in the CSST Ultra-Deep Field Survey
Minglin Wang, Yan Gong, Dejia Zhou +1
We study supernova (SN) classification using the Recurrent Neural Networks (RNNs) within the Chinese Space-station Survey Telescope Ultra-Deep Field (CSST-UDF) photometric survey a…
Investigating FRB 20240114A with FAST: Morphological Classification and Drifting Rate Measurements in a Burst-Cluster Framework
Long-Xuan Zhang, Shiyan Tian, Junyi Shen +59
This study investigates the morphological classification and drifting rate measurement of the repeating fast radio burst (FRB) source FRB 20240114A using the Five-hundred-meter Ape…
Polarization Position Angle Swing and the Rotating Vector Model of Repeating Fast Radio Bursts
Xiaohui Liu, Heng Xu, Jiarui Niu +23
Fast radio bursts (FRBs), typically highly polarized, usually have a nearly constant polarization position angle (PA) during each burst. Some bursts show significant PA variations,…
The FAST Galactic Plane Pulsar Snapshot survey: VIII. 116 binary pulsars
P. F. Wang, J. L. Han, Z. L. Yang +12
Finding pulsars in binaries are important for measurements of the masses of neutron stars, for tests of gravity theories, and for studies of star evolution. We are carrying out the…
The FAST Galactic Plane Pulsar Snapshot survey: VI. The discovery of 473 new pulsars
J. L. Han, D. J. Zhou, C. Wang +13
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is the most sensitive telescope at the -band (1.0-1.5 GHz) and has been used to carry out the FAST Galactic Plan…
Searching radio signals from two magnetars and a high-magnetic field pulsar and the serendipitous discovery of a new radio pulsar PSR J1935+2200
Lang Xie, J. L. Han, Z. L. Yang +8
Magnetars are slowly rotating, highly magnetized young neutron stars that can show transient radio phenomena for radio pulses and fast radio bursts. We conducted radio observations…
Ninety percent circular polarization detected in a repeating fast radio burst
J. C. Jiang, J. W. Xu, J. R. Niu +34
Fast radio bursts (FRBs) are extra-galactic sources with unknown physical mechanisms. They emit millisecond-duration radio pulses with isotropic equivalent energy of $10^{36}\sim10…
Scintillation velocity and arc observations of FRB 20201124A
Ziwei Wu, Weiwei Zhu, Bing Zhang +18
We present the scintillation velocity measurements of FRB~20201124A from the FAST observations, which reveal an annual variation. This annual variation is further supported by chan…
FAST pulsar database: I. Polarization profiles of 682 pulsars
P. F. Wang, J. L. Han, J. Xu +6
Pulsar polarization profiles are very basic database for understanding the emission processes in pulsar magnetosphere. After careful polarization calibration of the 19-beam L-band…
Pulsar Candidate Classification Using A Computer Vision Method Combining with Convolution and Attention
NanNan Cai, JinLin Han, WeiCong Jing +3
Artificial intelligence methods are indispensable to identifying pulsars from large amounts of candidates. We develop a new pulsar identification system that utilizes the CoAtNet t…
