Title: X-ray and EUV observations as diagnostic of accelerated electrons and atmospheric response in solar flares by Dr. Marina Battaglia (FHNW, Windish) Abstract: The signatures of solar flare accelerated electrons and atmospheric response to flare energy input are most readily observed in X-ray and EUV wavelengths. Modern observatories such as RHESSI, SDO, and IRIS provide …

Title: Structure of sunspot light bridges in the chromosphere and transition region by Dr. Reza Rezaei, Abstract: Light bridges are elongated structures with enhanced intensity embedded in sunspot umbra and pores. Using IRIS spectral data, we study properties of a sample of 60 light bridges in the chromosphere and transition region. Traces of photospheric light …

Title: The study of Active Galactic Nuclei variability on multiple timescales by Lia Sartori (ETH Zurich) Abstract: The study of Active Galactic Nuclei (AGN) variability on multiple timescales can provide important information about supermassive black hole accretion physics, as well as the black hole – host galaxy interaction and coevolution. AGN variability on human timescales …

Title: Solar surface magnetism without feature tracking. by: Andrei Gorobets (KIS, Freiburg) Abstract: The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behavior. Although feature-tracking algorithms have allowed us to deepen our understanding of this behavior, subjectivity plays an important role in the identification and tracking of …
