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 ...

New algorithm proposed for pulsar baseband data

Recently, senior engineer ZHANG Hailong, PhD student ZHANG Yazhou at the Xinjiang Astronomical Observatory, Chinese Academy of Sciences and their collaborators have developed a coherent dedispersion algorithm for pulsar baseband data.During the signal propagation, the pulsar signal is affected by the interstellar medium, so the pulse profile will be broadened and distorted, and the high-frequency signal will reach the Earth before the low-frequency signal. This pheno...

New method developed for layered structure detection in open clusters

The morphological study of open clusters can provide observational evidence for tracing the formation mechanism of star clusters and help to explore the evolution of star clusters. The morphology of open clusters on the two-dimensional p...The morphological study of open clusters can provide observational evidence for tracing the formation mechanism of star clusters and help to explore the evolution of star clusters.
