A research team led by the National Astronomical Observatories of the Chinese Academy of Sciences, in collaboration with international partners, has released the strongest evidence to date of disk-jet co-precession in the TDE known as AT2020afhd—a long-predicted outcome of spacetime dragging caused by a spinning black hole.
A research team from the Institute of Modern Physics has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27. These precise measurements provide crucial information for determining the nuclear reaction rate during X-ray bursts, advancing our understanding of how elements are synthesized under such extreme conditions.
A new study sheds light on how dark matter halos influence the physical properties and observational characteristics of accretion disks surrounding black holes. This study was led by the Yunnan Observatories of the Chinese Academy of Sciences.
A research team from the Yunnan Observatories of the Chinese Academy of Sciences, in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects (COs)—including black holes, neutron stars, and white dwarfs—accrete matter within active galactic nucleus (AGNs) disks. This work provides new insights into the evolution of these objects in extreme cosmic environments.
Researchers led by Profs. ZHANG Qingli and JIANG Haihe from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have developed a high-symmetry gradient-doped Nd:YAG laser crystal designed for dual-end pumping configurations. This innovation significantly mitigates thermal effects and improves laser performance.
A research team led by Dr. LI Lu and Prof. SHAO Zhengyi from the Shanghai Astronomical Observatory has released a new, homogeneous catalog of physical parameters for 1,232 open clusters derived from Gaia DR3 data.
