It was found that the width of the SPS of the received radiation for sufficiently strong absorption in the plasma is greater than in the collisionless plasma; the spectral maximum is substantially displaced with respect to the direction to the source.

The graduate textbook explains the theory of charged particle motion in weakly inhomogeneous electric and magnetic fields, how the magnetic confinement of a collisionless plasma works at an individual particle level, the ensemble-averaged kinetic equation, and how fluid equations are obtained by taking low-order moments of the kinetic equation.
According to University of Warwick astrophysicist Khurom Kiyani, "The particles in this "collisionless plasma" may too spread out to collide with each other but this could indicate that they can, and do, interact with waves and surfing these ideal waves is what allows them to dissipate their energy."
Intergalactic space is believed to consist of a collisionless plasma mostly of hydrogen.
How do you heat an essentially collisionless plasma to the temperatures required for fusion and how do you accurately remotely diagnose the complex dynamics of the plasma at both large and small scales to test your understanding of the system?
It is a common knowledge that an incident EM wave can propagate in a collisionless plasma above electron plasma frequency [[omega].sub.p]/2[pi].
