A pair of gigantic gamma-ray bubbles centered on the core of the Milky Way galaxy were discovered by the Fermi Gamma-ray Space Telescope 10 years ago. The question of how they were formed still remains as a mystery. Recently, researchers at Shanghai Astronomical Observatory presented a new model, explaining for the first time the origins of both the Fermi bubbles and the Galactic center biconical X-ray structure discovered in 2003 simultaneously.presented a new model, explaining for the first time the origins of both the Fermi bubbles and the Galactic center biconical X-ray structure discovered in 2003 simultaneously.

A Novel Method to Weigh the Milky Way with Its "Missing" Baryons

[ November 16 , " Processing full - scale Square Kilometre Array workflow on the Summit supercomputer " , with the participation of Professor Tao An and Mr . Baoqiang Lao of the Shanghai Astronomical Observatory ( SHAO ) .DALiuGE is able to manage up to tens of millions of tasks simultaneously , can execute data streams of up to Tb/s . DALiuGE is highly resilient to node errors , and experiments have shown that GPU nodes execute with an efficiency of up to 87% .

Galaxies are the building blocks of the visible universe , inhabiting a variety of environments .Observations show that over half of the galaxies are located in group systems which have members from a few to dozens .One of the important observational samples of the LAMOST spectral survey is to supplement the missed main sample galaxies in the SDSS . The combination of these surveys constitutes the largest spectroscopic identified CGs and CG candidates so far .News Contact : ZUO Wenwen , Shanghai Astronomical Observatory , wenwenzuo @ shao . ac . cn.

Using radio telescopes from five continents , astronomers prove the existence of a narrow stream of material ( jet ) emerging from the only gravitational wave event involving two neutron stars observed so far .This finding has been published in the scientific journal Science by an international team of astronomers , including researchers from the Shanghai Astronomical Observatory ( SHAO ) .Link to paper : G .

Supposing a distant active black hole is vomiting towards you , what will you see ?Recently , a research group led by Prof . WANG Zhongxiang from Shanghai Astronomical Observatory discovered a month-long Quasi-Periodic Oscillation ( QPO ) from such a black hole .Since our viewing angle to the jet ’ s emission undergoes periodic changes , the observed brightness will be quasi-periodically modulated .

A research team led by Dr. KONG Dali from Shanghai Astronomical Observatory (SHAO), Chinese Academy of Sciences found that multiple possibilities of zonal winds structure could exist using the Juno spacecraft’s measurements. They also present some weaknesses in the earlier influential paper published on Nature. This work has been published on one of the top 4 famous periodicals, the Proceedings of the National Academy of Sciences of the United States of America.
