Critical analysis of solar hard X-ray observations

The impulsive phase of a solar flare hard X-rays emission is a rich source of information to understand the physics processes acting during the flare phenomenon. Particularly, in some cases, it shows the superposition of many intensity variations with time scales of tens to tenths of seconds. Lookin...
