How molecular clouds survive the galaxy's harsh outskirts

a research team used the IRAM 30-meter telescope in Spain to observe a large number of molecular clouds at the Galactic edge with a Galactocentric distance of 14-22 kpc. In conjunction with the CO (1-0) data from the "Milky Way Imaging S...The outskirts of the Galaxy are ideal laboratory to study molecular clouds and star formation in a metal-poor environment. Different from the inner Galaxy (such as solar neighborhood), the molecular gas environment in this region lacks a...

Study Uncovers Magnetic Properties in Spider Pulsar Eclipse Regions

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), the researchers conducted high-sensitivity observations of some spider pulsars. By measuring the shift of the linear polarization position angle, the study successfu...Spider pulsars are a unique class of millisecond pulsar binary systems, characterized by eclipses observed in the radio band. In such systems, the pulsar's radiation and high-energy particle winds irradiate the companion star, gradually ...
