New Milky Way mosaic reveals nearly 1,000 strange 'filaments' at the heart of our galaxy
publishedThis MeerKAT image shows the complex emission from the galactic center super bubble, which is is traversed by many parallel radio filaments. The bright dot near the center of this region is the black hole Sagittarius A*.
Radio waves penetrate the intervening dust that obscures the view of this region at other wavelengths of light.
The new mosaic has also revealed nearly 1,000 mysterious strands that stretch up to 150 light-years long and possess strong magnetic fields. These filaments are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. These new findings confirm that all these strands each possess a magnetic field"much higher than what we usually expect from the galaxy," Yusuf-Zadeh told Space.com. Now"we need a theoretical model to explain how the magnetic field is amplified to such high values."
"This is the first time we have been able to study statistical characteristics of the filaments," Yusef-Zadeh said in the statement."By studying the statistics, we can learn more about the properties of these unusual sources.
