TalkThe loopy Sun: resolving the small-scale solar magnetism
Solar magnetism may look deceptively boring (a rather common star with relatively low activity). As it turns out, even the most quiet areas of the Sun (away...

TalkThe stochastic, intermittent nature of quiet Sun magnetism
The quiet Sun (the 99%, or more, of the solar surface not covered by sunspots or active regions) is receiving increased attention in recent years; its role on...
