YI-FU CAI     蔡一夫

Present Position: Professor
Affiliation: Department of Astronomy, School of Physical Sciences, University of Science and Technology of China; Office: 1223
Research Interests: I am a theoretical cosmologist. My research focuses on some fundamental questions for cosmology, such as, the nature of the big bang, the origin and future destiny of our universe, how the black holes and the galaxies formed. Particularly I work on:
Bouncing Cosmology, Inflation in String Theory, Dark Energy, Cyclic Universe, Cosmic String and Black Hole Physics.

WENTAO LUO     罗文涛

Present Position: Assistant Professor
Affiliation: Department of Astronomy, School of Physical Sciences, University of Science and Technology of China; Office: TBD
Research Interests: My main research field is accurate image procesing for weak lensing study, weak lensing signal measurement and modeling. Weak gravitational lensing is a powerful probe of our universe, especailly the dark sectors. Galaxy-galaxy lensing, as the first order measurement, can capture the halo mass of galaxies with different properties, or clusters of galaxies. Cosmic shear is the second order weak lensing statistics, and sensitive to the amplitude of density fluctuation. With the help of wide imaging surveys like DES, HSC, KiDS, Vera Rubin Telescope and WFST (Wide Field Survey Telescope), weak lensing will provide tighter constraints of cosmological models and better our standing of the universe.
