CUHK Researchers Contribute First Black Hole Image from Milky Way’s Heart

After five years of effort, the first image of Sagittarius A*, 26,000 light-years away at the centre of the Milky Way, produced by the Event Horizon Telescope, has proved it to be a supermassive black hole. A CUHK scholar and a student from the Department of Physics are Hong Kong’s only participants in the team and have studied the simulation of gas movement and the mechanism of infalling gas around the black hole using supercomputers to help unravel the mystery of black holes……

Two CUHK Scholars Excel with Honours in the Field of Optics

Applications of quantum sensing technology can be found in a wide range of settings, including medical imaging, prediction of weather patterns and even analysis of seismic activity. Professor Renbao Liu from Physics of CUHK has received the 2022 Willis E. Lamb Award for Laser Science and Quantum Optics for his contribution to spin decoherence and quantum sensing research. He and Professor Chester Shu from Electronic Engineering have also been elected Fellows of a prestigious society, highly commending their research achievements……

Gravitational Waves from Dying Stars Clues to Origin of Life

Travelling from the core of collapsing stars, newly detected gravitational waves may tell us about the meltdown which leads to these massive supernovas. Thrust into the universe from the explosions of dying stars, their ashes give birth to new worlds, so understanding supernovas is a step to ultimately understanding our origins......

Fresh From the Garden: Display Ozone’s Harm to Plants

An “ozone garden” is where a CUHK research team studied bean plants attempting to grow under Hong Kong’s rising ozone skies in the first plant-based measurement of ozone in the South China Region. Even though it was Spring and in the countryside, the ozone eroded the beans and stressed them into opening more flowers, forcing them to wither more quickly……

Public Lectures to Broaden Knowledge during the Pandemic

To encourage students to keep learning at home during the pandemic, CUHK is introducing the “Class Acts” CUHK Online Talk Series. Nine outstanding scholars will deliver short lectures on different areas of expertise through a video conferencing platform. The first one, given by CUHK’s Provost, will be held on 20 March……
