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…
Characterizing the FRB host galaxy population and its connection to transients in the local and extragalactic Universe
Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal +23
We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky V…
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…
Magnetic fields in our Milky Way Galaxy and nearby galaxies
JinLin Han
Magnetic fields in our Galaxy and nearby galaxies have been revealed by starlight polarization, polarized emission from dust grains and clouds at millimeter and submillimeter wavel…
Neutron Star Kicks in Isolated and Binary Pulsars: Observational Constraints and Implications for Kick Mechanisms
Chen Wang, Dong Lai, JinLin Han
We study observational constraints on neutron star (NS) kicks for isolated pulsars and for neutron stars in binary systems. We are particularly interested in the evidence of kick-s…
Magnetism Science with the Square Kilometre Array
George Heald, Sui Ann Mao, Valentina Vacca +41
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe. Magnetic field…
Pulsars as excellent probes for the magnetic structure in our Milky Way
JinLin Han
In this invited talk, I first discuss the advantages and disadvantages of many probes for the magnetic fields of the Milky Way. I conclude that pulsars are the best probes for the…
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…
Spin-Kick Correlation in Neutron Stars: Alignment Conditions and Implications
Chen Wang, Dong Lai, JinLin Han
Recent observations of pulsar wind nebulae and radio polarization profiles revealed a tendency of the alignment between the spin and velocity directions in neutron stars. We study…
Polarization Changes of Pulsars due to Wave Propagation Through Magnetospheres
Chen Wang, Dong Lai, JinLin Han
We study the propagation effects of radio waves in a pulsar magnetosphere, composed of relativistic electron-positron pair plasmas streaming along the magnetic field lines and coro…
