Brightness, Colour, Polarisation: A Multi-Instrument Observation Campaign of the Gorizont-6 Satellite
Robert J. S Airey, Paul Chote, Klaas Wiersema +15
We present a coordinated multi-instrument photometric and polarimetric study of the defunct geosynchronous satellite, Gorizont-6. This observation campaign combined wide-field mult…
The gas streamer G1-2-3 in the Galactic Center
S. Gillessen, F. Eisenhauer, J. Cuadra +61
The black hole in the Galactic Center, Sgr A*, is prototypical for ultra-low-fed galactic nuclei. The discovery of a hand-full of gas clumps in the realm of a few Earth masses in i…
Polarization resolved hyperspectral imaging of the beetle Protaetia speciosa jousselini
Peyman Soltani, Milan ten Hacken, Arie van der Meijden +2
Understanding and classifying chiral structural color of scarab beetles across the phylogenetic tree is an important scientific tool to explore the origins of the homochiral optica…
High-contrast spectroscopy with the new VLT/ERIS instrument: Molecular maps and radial velocity of the gas giant AF Lep b
Jean Hayoz, Markus Johannes Bonse, Felix Dannert +66
The Enhanced Resolution Imager and Spectrograph (ERIS) is the new Adaptive-Optics (AO) assisted Infrared instrument at the Very Large Telescope (VLT). Its refurbished Integral Fiel…
Polarization aberrations in next-generation Giant Segmented Mirror Telescopes (GSMTs). II. Influence of segment-to-segment coating variations on high-contrast imaging and polarimetry
Jaren N. Ashcraft, Ramya M. Anche, Sebastiaan Y. Haffert +8
Direct exo-Earth imaging is a key science goal for astronomy in the next decade. This ambitious task imposes a target contrast of ~10^-7 at wavelengths from I to J-band. In our pri…
Deep imaging of three accelerating stars using SHARK-NIR and LMIRCam at LBT
D. Mesa, R. Gratton, V. D'Orazi +29
The combination of detection techniques enhances our ability to identify companions orbiting nearby stars. We employed high-contrast imaging to constrain mass and separation of pos…
