New Methods Unlock Blazar Secrets

The researchers have applied the advanced time-series analysis methods to the one-year long Transiting Exoplanet Survey Satellite (TESS) of the radio blazar 3C 371. Blazars are the special class of active galactic nuclei (AGN) which are known to have very high variability that can be used extensively to study these compact systems and is determined by characteristic timescales. The real observationa...

Astronomers confounded by a mysterious million solar-mass dark object whose inner structure defies explanation

An international team of astronomers have uncovered what may be a new type of unseen dark object in the distant Universe that doesn’t seem to resemble anything observed before. The object, which has a mass of about one million times tha...

Peering into AI "Black Box": Interpretable Neural Networks Help Reveal the Nature of Dark Matter

The researchers developed an interpretable artificial intelligence framework named the Convolutional Kolmogorov–Arnold Network (CKAN) for studying the properties of dark matter on galaxy-cluster scales. HUANG Zhenyang, a master’s student at the Xinjiang Astronomical Observatory (XAO), Chinese Academy of Sciences, under the supervision of Prof. WANG Na and Senior Engineer LIU Zhiyong,developed an interpretable artificial intelligence fr...

Study Unveils Secrets of Interstellar Scintillation in Millisecond Pulsar

The researchers revealed detailed scintillation characteristics of the millisecond pulsar B1937+21. Pulsars, often called “cosmic lighthouses”, emit regular radio pulses. As these signals traverse the turbulent interstellar space, they experience scintillation - similar to the twinkling of starlight. This phenomenon serves as a power...

Unveiling Sibling Star Clusters in the Milky Way: New Advances in Systematic Identification and Classification

Researchers have carried out a large, systematic study of binary open clusters in the Milky Way.Stars usually form in clusters, and such clusters can also form in pairs or groups. Binary clusters (BCs), defined as pairs of open clusters closely associated both in position and kinematics. Their formation records how stars arise with...

Researchers reveal significant role of interstellar PAHs in molecular clouds

Researchers have made new progress in the study of polycyclic aromatic hydrocarbons (PAHs) in molecular clouds.Polycyclic aromatic hydrocarbons (PAHs) are important carriers of organic matter in the universe. They, as organic molecules, not only play a central role in interstellar chemistry but are also closely related to the origin of prebiotic ...
