Radio Emission from the Milky Way

摘要

In the last 5-10 years, wide-field imaging capabilities and effective mosaicing algorithms have made possible a variety of ambitious interferometric surveys of the Galaxy, resulting in images of unprecedented sensitivity and resolution. Here I discuss some of the highlights from these new surveys. Amongst the new results are the identification of many new supernova remnants in confused regions, spectacular low frequency images of the inner Galaxy with the VLA, and some remarkable new insights into the structure of the Galactic magnetic field from linear polarization.
