题目/Title: Neutron Star Population in Nearby Galaxies: A Scientific Goal of High-Energy Survey

主持人/Host: 陶炼/Lian TAO

摘要/Abstract:

In current astrophysical research, the majority of observed neutron stars fall into two main categories: 1) Pulsars, characterized by emission pulses lasting for seconds or less; and 2) Millisecond magnetars, which are produced in catastrophic events and exhibit extremely strong magnetic fields and rapid rotation. However, there is a notable scarcity in the detection of young neutron stars that bridge the gap between these two populations. My presentation will focus on exploring the diverse observational characteristics of the neutron star population as a whole. Furthermore, I will delve into the potential existence and properties of various neutron star populations that may be revealed through ongoing and future high-energy surveys of nearby galaxies. This includes investigating how these surveys can help us uncover and study the young, transitional neutron stars that are currently underrepresented in our observations.

个人简介/Biography:

Yuan-Pei Yang (杨元培) is an Associate Professor and PhD Supervisor at the South-Western Institute for Astronomy Research (SWIFAR), Yunnan University. He obtained his Ph.D. from Nanjing University in 2016. Subsequently, he was a Postdoctoral Fellow at the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University from 2016 to 2019, during which he was selected for the 2016 China Postdoctoral Innovation Talent Support Program. Dr. Yang's research focuses on high-energy astrophysics, Fast Radio Bursts (FRBs), and astrophysical radiation mechanisms. He has authored or co-authored 78 papers in international astronomical journals, including 39 as first or corresponding author, accumulating over 2500 citations with an H-index of 29 (NASA/ADS). His work has been recognized with the IOP China Top Cited Author Award four times and has been prominently cited in leading international review articles and journals (including ARAA, RvMP, and Nature). Dr. Yang actively contributes to the academic community, serving as a long-term reviewer for prestigious international journals such as Nature Astronomy, ApJ, MNRAS, Science Bulletin and RAA. He has also led theoretical analysis efforts contributing to several significant international discoveries in Fast Radio Burst research.
