Title: Anisotropies in Compressible MHD Turbulence: Probing Magnetic Fields and Measuring Magnetization Authors: Yue Hu, Siyao Xu, and A. LazarianFirst Author’s Institution: Department of Physics, University of Wisconsin-Madison, Madison, WI, USADepartment of Astronomy, University of Wisconsin-Madison, Madison, WI, USAStatus: Accepted to ApJ [closed access]Horace Lamb, who was a British applied mathematician and author of several influential texts on fluid dynamics, once said: “I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former, I am rather optimistic.” In fluid dynamics, turbulence refers to irregular flows in which eddies, swirls, and flow instabilities occur. Turbulence is considered one of the most challenging problems in physics. Now, can you imagine how much more challenging it becomes if we add magnetic fields into the fluid? And now, move it all many light-years away into space. It becomes almost impossible to study! However, the authors of today’s paper manage to successfully deal with this problem.
Magnetic fields rule the structureMagnetic fields are one of the key factors that regulate dynamical processes in molecular clouds ...
