“Hunting for Treasures” with AI: Astronomers Detected Rare Neutral Atomic-carbon Absorbers with A Deep Neural Network

This study highlights a groundbreaking discovery of weak neutral carbon absorption lines in quasar spectra from early galaxies, observed through the Sloan Digital Sky Survey with the aid of an AI-driven deep neural network. This marks the first time such technology has been employed to detect these features. The study of these abso...

Researchers Reveal Dynamic View of Massive Protocluster Evolution by ALMA

The origin of stellar clusters is the key mystery in astronomy. Now with the best submillimeter interferometry telescope ALMA, scientists are tracing back their baby stage—protostellar clusters, depicting their complete and dynamic formation and evolution scenario.

Researchers Prove Validity of Black Hole Jet Formation Model

An international team led by Dr. YUAN Feng from Shanghai Astronomical Observatory, CAS investigated the validity of the two main models of black hole jets by calculating the radiation predicted by these models and comparing it with observations of the M87 jet, and found that the "extraction of black hole rotational energy" model ac...

Researchers Discover Emission from Secondary Black Hole in Binary System of Blazar OJ 287

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...
