OJ 287 is recognized as a binary black hole system of which the signals have been associated either with the ultramassive primary black hole or with the gas accretion disk surrounding it. From the most comprehensive polarization monitoring to date, the researchers claim they are able to “see” the secondary black hole for the firs...

The nearby radio galaxy M87 has recently been discovered to exhibit an oscillating jet. This investigation found the jet swinging up and down with an amplitude of about 10 degrees. Through the extensive analysis of data observed from 2000 to 2022 by various international networks of radio telescopes, the research team unveils a rec...

Astronomers discovered five Green Pea galaxies with double-peaked narrow lines among nearly 1550 Green Pea galaxies. The study suggests that these objects may originate from dual AGN mergers, potentially revealing the co-evolutionary characteristics of a special class of high-mass galaxies and supermassive black holes.

Recently, the Group of Satellite Navigation and Remote Sensing, led by Prof. Shuanggen Jin from Shanghai Astronomical Observatory, Chinese Academy of Sciences, investigated seasonal signals by the Earth’s surface loads using space geodetic observations. They studied displacements from Global Navigation Satellite System (GNSS) and ...

Recently, a research team successfully detected radio recombination lines (RRLs) of ions heavier than helium for the first time using the TianMa 65-m Radio Telescope (TMRT), operated by the Shanghai Astronomical Observatory (SHAO). Those lines were assigned to carbon and/or oxygen ions allowing measurements of elemental abundances ...

Recently, astronomers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences used a sample of emission line galaxies in the COSMOS field with two-epoch narrowband imaging separated by 12 years to study their optical variability. Only a small fraction of galaxies was found showing optical variability. Such var...

A research team from Shanghai Astronomical Observatory (SHAO) has recently completed a deep Q-band line scanning survey towards Orion KL using the Tianma 65 m radio telescope (TMRT), achieving the widest frequency coverage (35--50 GHz) and the highest sensitivity (~mK) spectra so far. In total, about 600 emission lines were detecte...
