Altmetric Top 100: NAOC-led study ranks 60th among the most thought-provoking research in 2019

The 2019 Altmetric Top-100 features a high-impact article led by Xiaodian CHEN and Licai DENG at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC). Their research, pursued jointly with colleagues at Peking and Macquarie Universities and which was published in Nature Astronomy, ranked 60th this year, ahead of more than 2.7 million research outputs tracked by Altmetric.



The article,“An intuitive 3D map of the Galactic warp’s precession traced by classical Cepheids”, revealed the first three-dimensional picture of the Milky Way's distribution of 1339 young variable stars known as Cepheids. The new photo shows clearly that our Milky Way's starry disk is warped and S-shaped in a progressively twisted spiral pattern. Theseresults attracted eye-catchingcoverage by more than 1600 international media outlets. (Explore a cross-section of these stories here:



The annual Altmetric Top-100 highlights research that has generated significant international online attention and discussion – from patents and public policy documents to mainstream media, blogs, Wikipedia, and social media platforms. Chinese institutions led or contributed to four of the top-100 articles in 2019.
