Cluster cosmology has entered into a new and exciting era allowing us to probe the universe at an unprecedented scale, thanks to the deployment of large-sky surveys in multiple wavelengths and the rec...
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 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...
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...
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...
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...
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...
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...
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...
Astrometry opened the era of modern astronomy/physics and plays a crucial role in contemporary astronomy, including the measurement of the three-dimensional structure of the Milky Way, black hole dete...
