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 normal ones. Recently researchers fro...

OH masers, the first astrophysical maser ever detected in the space, opened an exciting and rapidly growing area of research. As a high-sensitivity survey of OH masers in our Galaxy, the Southern Parkes Large-Area Survey in Hydroxyl (SPLASH) has shown typical features of OH masers. However, due to its limited spatial resolution, it...

It is believed that blazars show flux variability in complete electromagnetic (EM) spectrum on all possible timescales varying from few minutes to several years. A recent study led by Alok C. Gupta, a visiting scientist of Shanghai Astronomical Observatory (SHAO) shows that blazars are not necessarily variable in all EM bands on ...

In about 5 billion years, our sun will evolve to be a red giant, expanding out beyond the orbit of Venus. When our sun has used up its fuel, its core will collapse and its outer gas layer will be expelled by strong stellar winds. After being illuminated by the ultraviolet radiation of the hot luminous core, the dissipated gas laye...
