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...

A Newly Identified Degeneracy in Microlensing Two-Planet Systems
Credit: AI DoubaoA new study published in The Astronomical Journal (AJ) reports the discovery of a previously unrecognized degeneracy in microlensing two-planet systems, highlighting the need for caution when interpreting complex planetary signals in future space-based microlensing surveys.The two planets were discovered through the microlensing event KMT-2022-BLG-1818, with the planetary signa...

Tsinghua University and Leiden Observatory Jointly Reveal the Diversity of Obscured Quasars and Supermassive Black Hole Growth in the Universe
Abstract: An international research team led by the Department of Astronomy at Tsinghua University has successfully identified 23 of the most luminous dust-obscured quasars (Type-2 QSOs) from the 'cosmic noon' (2 to 3 billion years after the Big Bang corresponding to redshift z = 0.88–3.49), using spectroscopic observations from the world's most advanced ground-based telescopes, Keck and Gemin...
