Beijing: Chinese astronomers and their international peers have refreshed the limits of galactic observation using the spherical spherical radiotelescope of the opening of five hundred meters of China (rapid) and the Metrekat networks of South Africa when they finished high precision observations of the globular clusters of the Milky Way.
The globular clusters, some of the oldest celestial bodies in the Milky Way, generally consist of millions of stars, including pulsar neutron stars. These highly magnetized pulsars emit regular electromagnetic pulses with exceptional precision, which transport precious information on interstellar and magnetic fields, traveling through a large space to reach the earth.
Fast is capable of capturing the weakest cosmic undulations, the signals of pulsars located for millions of light years, while the 64-year-old Meerkat network focuses on monitoring signals in a wider sky area.
The project led by the University of Tsinghua marks the first deep collaboration between these two advanced radio stations in the study of globular bunches.
Participating astronomers have attributed the accomplishment to synchronization between the telescopes of the two nations.
“By combining equipment from the southern and north hemispheres, which are of different capacities, we have more than doubled our observation sample,” said Professor Li Di of Tsinghua University.
This collaboration managed to obtain polarization rotation measures of 43 pulsars of eight globular clusters. These measured results are a key indicator of the cosmic magnetic field force. In particular, research revealed that seven of these globular bunches did not show detectable ionized gas, indicating an exceptionally “clean” environment, according to astronomers.
“We call it the” dustless kingdom “among the ancient celestial bodies of the Milky Way. Why did these globular clusters remained so clean after such a long process of evolution? This is a new question for us. Scientists now speculate that many smaller but highly active neutron stars, “hold” constant radiation stars “.
The two parties expect new collaborations on pulsar mutations and interstellar turbulence, and even the exploration of possible signals of extraterrestrial civilizations.
