报告人简介

　　Dr. Jun Yang received her Ph.D. in Physics & Astronomy from University of Massachusetts (UMass) in 2017. From 2015 to 2017, she worked as a SAO Predoctoral Fellow at Harvard-Smithsonian Center for Astrophysics. From 2017 to 2019,she worked as a Postdoctoral Fellow at University of Utah. Since 2019, she worked as a Postdoctoral Scholar at MIT Kavli Institute.

　　Dr. Jun Yang's research focuses on neutron stars, stars, and interstellar medium with multiwavelength observations and modeling. Her expertise in pulsars is complemented by her broacstudy of space physics. Jun's experience leads her interests in new type of pulsar systems, for example, pulsar planets, ultra-luminous X-ray pulsars, and Millisecond pulsars that could also be used to trace axion darkmatter profile, probe gravitational waves, and test fundamental physics.

报告简介

　　The formation of compact objects-- neutron stars and black holes--and their evolution in stellar systems make them a unique resource to study their emission and interaction with the interstellar medium (ISM), planetary ionospheres and magnetospheres including Earth.

　　To understand the phenomenon above and the mystery of the universe, I started my career by studying the Earth’s atmosphere. Inspired by the Earth’s magnetosphere, I looked further towards more extreme magnetic environments, including the magnetosphere of pulsars. Currently, I study metal composition of the ISM, which perfectly bridges the ionospheric and pulsar sciences. I will talk about part of my research focusing on pulsars:

　　extract science from the pulsar library I have built for Magellanic Cloud pulsars, probe Galactic pulsar 4U 1907+09 and its variation of absorbing columns at different orbital phases. These important topics define my interest and plans: e.g., search for pulsars near the Galactic Center (GC) which would provide exciting opportunities for probing gravitational potentials, dark matter, and magnetoionic environments near the GC.
