New MeerKAT Image Reveals Radio-Emitting Filaments in Milky Way’s Center astronomy space science
“Those observations showed linear, magnetized features running mainly perpendicular to the Galactic plane,” Professor Yusef-Zadeh and his colleagues explained.
The new MeerKAT image shows 10 times more such filaments than previously discovered, enabling the astronomers to conduct statistical studies across a broad population of filaments for the first time. The new MeerKAT image of the Milky Way’s center is shown with the Galactic plane running horizontally across the image. Many new and previously-known radio features are evident, including supernova remnants, compact star-forming regions, and the large population of mysterious radio filaments. The broad feature running vertically through the image is the inner part of the radio bubbles, spanning 1,400 light-years across the center of the Galaxy.
And, while they already knew the filaments are magnetized, now they can say magnetic fields are amplified along the filaments, a primary characteristic all the filaments share. Filaments within clusters are separated from one another at perfectly equal distances — about the distance from Earth to the Sun.

A Supercomputer Gives Better Focus to Blurry Radio Images - Universe TodayWith better computers comes more battery imagery. Or at least that’s true most of the time. Supercomputers are extraordinarily good at image processing, so it’s normally worth it when a new algorithm comes along that they can turn their attention to. That’s exactly what happened with an algorithm recently developed by Ph.D. student Frits Sweijen … Continue reading 'A Supercomputer Gives Better Focus to Blurry Radio Images'
