... These graphs allow us to see where a positive slope in velocity space develops in relation to the required minimum velocity for Type III radio emission and hence at what distance along the field line a wave resulting in this sort of emission is created. Thus we can postulate where Type III emission ...

Ion-supported tori: a thermal bremsstrahlung model for the X
... The spectrum of the XRB, with its ~ 30-keV rollover, requires some spectral uniformity in its constituent sources. Since it resembles thermal bremsstrahlung in the 3-60 keV range, a mechanism which produces such radiation in galaxy nuclei would be particularly appealing. A way of standardizing the t ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
