Dynamos, the drivers of solar and stellar activity
Following Cowling's anti-dynamo theorem of 1933, there was a long period during which the very existence of dynamos was unclear. Even with the emergence of...

PublicationMultidimensional energy transfer by radiation in the solar atmosphere
Both linear and nonlinear analysis are used to gain a better understanding of the effects of multi-dimensional transfer of energy by radiation in spatially...

PublicationNo Evidence for Critical Balance in Field-aligned Alfvénic Solar Wind Turbulence
The properties of Alfvénic solar wind turbulence have been studied for decades using spacecraft measurements. In particular, the observation of spectral...

PublicationQuiet Sun Magnetic Fields
The seemingly un-magnetized part of the solar surface is not really un-magnetized. It is occupied by magnetic structures producing low polarization which...

TalkSolar-terrestrial relations – combined remote sensing and in-situ data
The Sun is an active star that influences the Earth as well as the entire solar system. Most dynamic phenomena on the Sun are observed as coronal mass ejections...

PublicationThe Magnetic Landscape of the Sun's Polar Region
We present observations of the magnetic landscape of the polar region of the Sun that are unprecedented in terms of spatial resolution, field of view, and...

PublicationThe profuse optically-thin irregularities of the photospheric magnetic fields
The highly irregular nature of most photospheric magnetic fields is analyzed here, trying to emphasize the connection between photospheric fluctuations and...
