Cause of chromospheric opposite polarity intrusions discovered in Sunrise III/SCIP data: MURaM-ChE simulations point to twisted flux ropes
Patrick A. Ondratschek, Damien F. Przybylski, Robert H. Cameron +33
The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) instrument onboard the balloon-borne Sunrise III observatory provided new high-resolution observations of the solar chr…
Ultrafast order-selective electron imaging and spectroscopy
Jan Philipp Bange, Till Domröse, Claus Ropers +3
Ultrafast pump-probe spectroscopies in energy and momentum have become indispensable for probing non-equilibrium dynamics in quantum materials, revealing pathways in ultrafast ener…
Second-Generation Fabry-Pérot Unit for CARMENES
Hanna Lina Pleteit, Michael Debus, Sebastian Schäfer +1
CARMENES consists of two high-resolution spectrographs located at the Calar Alto 3.5m telescope, covering the wavelength range from 520nm to 1710 nm. The original Fabry-Perot (FP)…
The MICADO first light imager for the ELT: eliminating vibrations and excessive earthquake-loads on specific subsystems
H. Nicklas, S. Schäfer, H. Anwand-Heerwart +3
Ensuring earthquake resilience is paramount for the upcoming Extremely Large Telescope (ELT). Instruments positioned on the ELT's Nasmyth platform are anticipated to endure substan…
Observing the integrated and spatially resolved Sun with ultra-high spectral resolution
S. Schäfer, K. Royen, A. Huster Zapke +2
The Institute for Astrophysics Göttingen operates a solar observatory that combines a 50\,cm siderostat with (1) a vacuum vertical telescope, (2) a very high resolution Fourier Tra…
Fiber-coupling of Fourier Transform Spectrographs
S. Schäfer, P. Huke, D. Meyer +1
Fourier Transform Spectrographs (FTS) are versatile tools for measuring accurate, high resolution spectra. They are internally calibrated by a reference laser that runs in parallel…
