Shanghai TMRT discovered abundant complex organic molecules in the Galactic c... [2017-10-11]
Complex organic molecules (COMs) are directly related to the origin of life on the Earth, thus understanding the property and formation mechanism of prebiotic molecules is key to study of astrobiology. Observations indicate that COMs are abundant in Galactic center giant molecular cloud Sagittari... more
APSG 2017 International Symposium Successfully Held in Shanghai [2017-09-08]
APSG 2017 International Symposium of Asia-Pacific Space Geodynamics ( APSG ) Program , with theme “ From Space Geodesy to Astro-Geodynamics ” , was successfully held in Shanghai , China , during 15-18 August .Meanwhile , it will not only deepen our understanding of the dynamics of the global Ea... more
Revealing radio structure of a quasar shinning in the early universe with hig... [2017-03-24]
Among the high-redshift quasars, the radio-loud subsample constitutes an attractive group since the radio jets are directly related to the SMBH activity. Until now, more than 100 quasars have been detected at z > 5 while the fraction of radio-loud ones is about 10 percent. Recently, a science tea... more
Seasonal Variations in GPS Station Positions? Temperature Variations Can’t B... [2017-03-16]
Compared with the observed annual deformations in GPS stations , they found that the seasonal GPS observations , the transverse displacements in particular , are better explained after considering the thermoelastic effects due to temperature variations .Annual contribution of the mass-loading ( b... more
“Unusual” Behavior of Active Galactic Nuclei in Quiescence! [2017-02-28]
It is found that the black hole mass, X-ray luminosity and radio luminosity follow a simple and linear relationship in logarithmic space, known as the “fundamental plane” of black hole activity. One key problem is, whether or not the quiescent AGNs follow the same fundamental plane as that of n... more
To Measure the Galactic extinction? From Cosmological Principle! [2017-02-27]
A group from astronomers in Shanghai Astronomical Observatory have completed a systematical study on Galactic dust extinction recently. Taking advantage of the most up-to-date large sky area u band galaxy catalog from the South Galactic Cap U-band Sky Survey (SCUSS), this study has obtained stati... more
