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...
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...
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 ...
X-ray spectroscopy is one of our main tools for studying the physical and chemical properties of the intracluster, intragroup, circumgalactic, and intergalactic media, and understanding their connecti...
The asteroids provide excellent opportunities to study the formation and early evolution of the Solar System. This is because they are small and can not retain heat efficiently, and thus cooled early ...
Nonconvex optimization is a central research topic in machine learning, mainly because the loss functions in many machine learning models (including neural networks) are typically nonconvex. However, ...
