My research interests are in the
field of High Energy Astrophysics. I started my work in this area by
working with Italian astrophysicist and data scientist
Giovanni Fossati,
in collaboration with
Edison Liang
and
Markus Boettcher.
Currently I work with
Martin Pohl.
The research focuses on the study of the variability of blazars,
a kind of active galactic nucleus(AGN). AGNs are
thought to be powered by Supermassive Black Holes
in the center. Blazars are thought to be AGNs
whose spin axes are along our line of sight, so the relativistic jets they
send out are directly coming towards us with very high velocity. The
relativistic beaming effect is the main reason why it looks so bright from
such a long distance (more than 100 million light years) and has such fast
(change a factor of 2 in
several hours) variability. The origin of these variations not
only is a very curious subject itself, but also provides us invaluable
information about the physical condition in the very close vicinity of the
Black Holes.
I have studied Space Physics when I
was in USTC. I had some research experience in solar physics with Dr. Chen,
Yao, and
Prof. Hu, Youqiu. I am
still very interested in solar flares and CMEs, which are also eruptive
phenomena, and are comparable to jets in some aspects.
