Core Insights - Tsinghua University, in collaboration with astronomers from Italy, Australia, Germany, and other countries, has conducted high-precision observations of globular clusters in the Milky Way using the Chinese FAST and South African MeerKAT telescopes, providing the most comprehensive measurements of magnetic field gradients and ionized gas upper limits to date [1] Group 1 - The research offers a clearer magnetic field map of the Milky Way, contributing to the understanding of cluster evolution and the galactic magnetic field [1]

Group 1 - The research conducted by Tsinghua University and international astronomers utilized the FAST and MeerKAT telescopes to perform a high-precision pulsar polarization survey of globular clusters, providing the most comprehensive measurements of magnetic field gradients and ionized gas limits to date [1] - The study observed 43 pulsars across 8 globular clusters, doubling the global sample size and creating a clearer map of the Milky Way's magnetic field [1] - The findings were published as a cover article in the journal "Science Bulletin" on May 20 [1] Group 2 - The research revealed that, apart from 47 Tucanae, other globular clusters lacked detectable ionized gas, contradicting theoretical models that predicted significant gas presence [2] - This unexpected finding suggests the existence of effective gas-clearing mechanisms within globular clusters, potentially driven by strong radiation winds from white dwarfs and young stars [2] - The results challenge existing theories of globular cluster evolution, prompting a reevaluation of current models [2]

Core Insights - A collaborative team from the University of Toronto, Princeton University, and the Australian National University has developed an innovative computer simulation technology that explores the interstellar medium (ISM) with unprecedented precision and scale [1][2] - The new model provides insights into astrophysical phenomena such as ISM, galactic magnetic fields, star formation, and cosmic ray propagation, and has been published in the latest issue of Nature Astronomy [1] Group 1: Model Capabilities - The new model achieves significant breakthroughs in size and detail, capable of simulating a spatial volume approximately 30 light-years across, with the smallest version reduced to about 1/5000 of that size [2] - It offers higher resolution and scalability, allowing for the simulation of dynamic changes in ISM density, which previous models could not account for [2] Group 2: Scientific Implications - The model utilizes observational data from the solar-Earth system to validate simulation results, indicating a better understanding of space weather and its effects on Earth [2] - Turbulence is a common phenomenon in various natural and engineering contexts, and the model enhances understanding of how magnetic fields influence gas flow and star formation, as well as the impact of cosmic weather events like solar storms on Earth [2]
