Fri, 2020-11-06On October 29th and November 4th, 2020, the research journal “Nature” published two articles on FRBs using FAST: 1) “Diverse polarization angle swings from a repeating fast radio burst source” and 2) “No pulsed radio emission during a bursting phase of a Galactic magnetar”. In both works, researchers from Kavli Institute for Astronomy and Astrophysics (Peking university), National Astronomical Observatory (Chinese academy of science), and University of Nevada formed the core team.

Wed, 2020-10-28A recent study revealed the actual evolutionary stage of lithium-rich stars by the Chinese astronomers is published in the Nature Astronomy on Oct.5. Yutao Zhou, the LAMOST Fellow from the department of astronomy at PKU, is involved in this study as the co-first author. By combining the LAMOST spectra with the asteroseismic data from Kepler, they find that most lithium-rich stars are located at the evolutionary stage of red clump instead of the red giant branch as previously thought. The findings challenge the previous theories of lithium enrichment, which is vital to resolve the problem of lithium origin.

Thu, 2020-09-24Astronomers have found that the key to understanding galaxies with "extreme" sizes, either small or large, may lie in their surroundings. In two related studies, an international team found that galaxies that are either "ultra-compact" or "ultra-diffuse" relative to normal galaxies of comparable brightness appear to reside in dense environments, i.e., regions that contain large numbers of galaxies. This has led the team to speculate that these "extreme" objects could have started out resembling normal galaxies, but then evolved to have unusual sizes through interactions with other galaxies.

Thu, 2020-08-06"This new study is a great example of how flexibility in observation scheduling allows NASA and ESA missions to study objects that evolve relatively quickly and look for longer-term changes in their average behavior," said Michael Loewenstein, a coauthor of the study and an astrophysicist for the NICER mission at the University of Maryland College Park and NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. "Will this feeding black hole return to the state it was in before the disruption event? Or has the system been fundamentally changed? We're continuing our observations to find out.” Two KIAA astronomers, Prof. Luis Ho and Ruancun Li, also participated in this discovery.

Sat, 2020-06-27Astronomers have discovered the second most distant quasar ever found, using the international Gemini Observatory and Cerro Tololo Inter-American Observatory (CTIO), Programs of NSF’s NOIRLab. It is also the first quasar to receive an indigenous Hawaiian name, Pōniuā’ena. The quasar contains a monster black hole, twice the mass of the black hole in the only other quasar found at the same epoch, challenging the current theories of supermassive black hole formation and growth in the early Universe.
