UV-Optical Colors as Probes of Early-Type Galaxy Evolution
... Cold Gas found in many early-type galaxies CMRs (Ferraras and Silk 2000) for early-types in cluster A851 (tobs= ~4.5 Ga) consistent with 10% of galaxy SF less than 500Ma UV-Upturn studies find blue colors in some early types can not be fully explained by old (EHB and later) stars ...

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.
