An International Team Led by Tsinghua University Probes the Architecture of the Young Planetary System AU Mic
In a recent study led by the Department of Astronomy at Tsinghua University, astronomers measured the spin–orbit architecture of two planets in the young planetary system AU Mic.Whether or not a planet’s orbit is aligned with the rotation of its host star provides an important clue to understanding the formation and history of planetary systems. In the Solar System, planet orbits are mostly a...

A cosmic lighthouse flashes every 44 minutes in a stellar graveyard
Summary: Astronomers have identified DART J1832-0911, a radio source that flashes every 44.27 minutes from inside the supernova remnant G22.7-0.2. As DART's first astronomical discovery, the source was found with DART and followed up by FAST, which detected a nearly 100% linearly polarized pulse, supporting the idea that the object is most likely a young neutron star slowed by materials left ov...

The Blue Eye Pulsar: Breaking Decades of Radio Silence
For decades, one class of neutron stars refused to speak in radio waves.An international research team led by Prof. Di Li of the Department of Astronomy at Tsinghua University has detected radio pulsations from the Central Compact Object (CCO) 1E 1207.4−5209, a young neutron star embedded in the supernova remnant PKS 1209−51/52. Published in Nature Astronomy, the discovery provides some of th...

A Stellar Dynamical Mass Measurement of a Supermassive Black Hole in the Early Universe
Introduction: On June 4, 2026, the journal Science published the paper "A stellar dynamical mass measurement of an inactive black hole at redshift 2," with Meng Gu, an assistant professor in the Department of Astronomy at Tsinghua University, as the 2nd author. Using James Webb Space Telescope (JWST) near-infrared integral field spectroscopy, together with the strong lensing magnification of a ...
