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 Sagittarius B2 (Sgr B2). Sgr B2(N), the main ...

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 team led by Prof. AN Tao from Shanghai ...

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...
