"Understanding the nature of the vast halos of gas surrounding galaxies is extremely important," explained co-researcher Samantha Barak of Yale University. "This reservoir of gas will serve as fuel for future star formation within the galaxy. It also absorbs gas remnants from supernova explosions"
Tracking the exact locations of the edge states allowed scientists to construct spatial maps of the local twist angles with unprecedented resolution and accuracy. These maps reveal a complex landscape pattern of valleys, peaks and saddle points

"The electrical properties of the material depend to a large extent on the exact twist angle. In other words, areas with different twist angles should be treated as different materials connected to each other, says Prof. Eli Zeldov
