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...
