Researchers propose new method for pulsar timing and RFI mitigation

There are several common challenges in the task of radio-frequency interference ( RFI ) mitigation for pulsar signals .Dr . SHAN Hao from the Xinjiang Astronomical Observatory ( XAO ) of Chinese Academy of Sciences conducted a study on R...Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency radio signals. Subsequent astrophysical ...

Researchers use correlation analysis method to find evidence of OJ 287 jet precession

YUAN Qi, a doctoral student from the Galaxy cosmology research group of Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, under the guidance of Prof. LIU Xiang and Prof. ZHANG Ming, analyzed the cross-correlation betw...OJ 287 is a typical blazar with relativistic jets, and because the jet point very close to the observer's line of sight, they show a strong beaming effect. At present, flares of about 12 years period have been observed in the optical ban...

Advances in Chemical Models for Prebiotic Molecules: Investigating Cyanamide and Its Isomers in the Interstellar Medium

Researchers from the Astrochemistry Group of Xinjiang Astronomical Observatory, Chinese Academy of Sciences, along with their collaborators, have published a study in the Monthly Notices of the Royal Astronomical Society, which outlines ...Prebiotic molecules are the building blocks of life, or the raw materials from which these building blocks formed, and are believed to have been delivered to Earth by comet-like objects. These molecules can develop within stars or planet...

Nocturnal Terrestrial Cloud Cover Monitoring at the Muztagh-ata Site

Since the beginning of site testing in January 2017, the ground-based cloud detection has been carried out at the Muztagh-ata site. XU Jing, a senior engineer from Xinjiang Astronomical Observatory, Chinese Academy of Sciences, along wit...For optical astronomical observatories, the cloud coverage during nighttime directly determines the available observing time (AOT) of telescope, which is the most basic parameter in astronomical observations. And using the ground-based ...
