Description
The results of a 2D numerical simulation of the rise of twisted magnetic flux tubes are sketched. The theoretical criterion for the minimum twist necessary to prevent the conversion of the tube into a pair of strong vortices is shown to be correct. The transition from a low-twist to a high-twist regime is exemplified. There is a sharp transition between the tube interior and the outside medium. A well-developed wake is formed, which however contains only a fraction of the original magnetic flux of the tube.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to
