Deciphering silicate cloud formation in the super-puff planet WASP-107 b
In a recent study led by the Department of Astronomy, Tsinghua University, a group of astronomers explained the silicate cloud features on a super-puff planet WASP-107 b with a self-consistent atmosphere model.The James Webb Space Telescope (JWST) opens up a new window to study the composition of exoplanet atmospheres. Benefiting from its broad wavelength coverage and extraordinary signal-to-no...

How Turbulence Arises in Black Holes
A research team led by Tsinghua University and the Institute for Advanced Theoretical Physics has revealed how black holes can exhibit turbulence-like phenomena similar to those found in fluids. Introducing a novel numerical relativity technique, the team was able to simulate gravitational waves directed into a black hole and observe its response. This approach enables a deeper understanding of...
