Probing the Cosmic Reionization History and the Earliest SMBHs Using Distant Quasars
As the most luminous non-transit objects, quasars are unique probes of the early Universe. I have been leading a wide-field reionization-era quasar survey, which has provided the first large statistic...

Cosmology & Dark Energy
Cosmology was once a mainly philosophical endeavour, but thanks to the exponential growth of astronomical data over the last decades, it has become a data driven field of science where we can study ph...

Physical Processes and Radiations around Neutron Stars
The environment around neutron stars features high magnetization, strong gravity, and relativistic particles. With radio, X-ray, and gravitational wave observations, neutron stars are perfect laborato...

Stochastic gravitational waves from Primordial Black Holes
The discovery of gravitational waves from the coalescence of binary black holes in 2015 has marked the dawn of the gravitational wave (GW) astronomy/cosmology. Besides the gravitational wave bursts fr...

Modeling Signals from Star--Compact-object Binaries
Precision radial velocity and photometric monitoring of a large number of stars may reveal hitherto overlooked populations of binary systems consisting of normal stars and unseen compact objects. I wi...

Mirror-image biology systems
The overwhelmingly homochiral nature of life has left a puzzle as to whether mirror-image biology systems based on a chirally inverted version of molecular machinery could also exist. We initially dev...

From the solar corona to stellar coronae
As the outermost layer of the solar atmosphere, the corona plays a key role in shaping the plasma and magnetic field environment of the solar system. The quiescent corona has a temperature of about on...

Fast and furious: reconnection-powered emission in relativistic jets and black hole coronae
Relativistic jets of blazars and magnetized coronae of highly accreting black holes routinely display non-thermal emission signatures, including fast and bright flares of high-energy emission. Yet, th...

An Update of the Chinese Survey Space Telescope Project
The 2m-aperture Chinese Survey Space Telescope (also known as the Chinese Space Station Telescope, CSST) is a major science project of China Manned Space Program. It is expected to start science opera...

Cold stellar streams in the Fornax cluster core
I will present recent results of the kinematics of planetary nebulae (PNe) and globular clusters (GCs) out to about 200 kpc from the center of the Fornax cluster. We have collected more than 2000 new ...
