A single picture for solar coronal outflows and radio noise storms
... radio noise storms. Noise storms are broadband emissions lasting for hours or days at frequencies between roughly 100 and 500 MHz. They are associated with active regions, but not directly with flares (for reviews, see Elgarøy 1977; Kai et al. 1985; Klein 1998). Noise storm observations were present ...

Frequency comb generation by CW laser injection
... Frequency comb lasers [1,2] have been around since the early 2000’s, enabling highly-accurate optical time and frequency measurements resulting in many applications [3–6]. Integrated optical frequency comb lasers would pave the way to an even broader application of comb technology because of low fab ...
