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.
