METIS: The Mid-infrared ELT Imager and Spectrograph
Bernhard Brandl, Felix Bettonvil, Roy van Boekel +13
The Mid-infrared ELT Imager and Spectrograph (METIS) will provide the Extremely Large Telescope (ELT) with a unique window to the thermal- and mid-infrared (3 - 13 microns). Its si…
Detecting habitable exoplanet atmospheres with LIFE, the Large Interferometer for Exoplanets
Sarah Rugheimer, Aiden Weatherbee, James Fecanin +21
A key goal of astronomers with the next generation telescopes is to detect signs of life in exoplanet atmospheres. NASA's next flagship is the Habitable Worlds Observatory (HWO). I…
PCS -- A Roadmap for Exoearth Imaging with the ELT
Markus Kasper, Nelly Cerpa Urra, Prashant Pathak +22
The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will be dedicated to detecting and characterising nearby exoplanets with sizes from sub-Neptune…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
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…
MIRI-LRS spectrum of a cold exoplanet around a white dwarf: water, ammonia, and methane measurements
Maël Voyer, Quentin Changeat, Pierre-Olivier Lagage +21
The study of the atmosphere of exoplanets orbiting white dwarfs is a largely unexplored field. With WD\,0806-661\,b, we present the first deep dive into the atmospheric physics and…
Atmospheric characterization of terrestrial exoplanets in the mid-infrared: biosignatures, habitability & diversity
Sascha P. Quanz, Olivier Absil, Daniel Angerhausen +45
Exoplanet science is one of the most thriving fields of modern astrophysics. A major goal is the atmospheric characterization of dozens of small, terrestrial exoplanets in order to…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
Beam calibration of radio telescopes with drones
Chihway Chang, Christian Monstein, Alexandre Refregier +3
We present a multi-frequency far-field beam map for the 5m dish telescope at the Bleien Observatory measured using a commercially available drone. We describe the hexacopter drone…
The nature of point source fringes in mid-infrared spectra acquired with the James Webb Space Telescope
Ioannis Argyriou, Martyn Wells, Alistair Glasse +10
The constructive and destructive interference in different layers of the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) detector arrays modulate the detected sign…
An Integrated System at the Bleien Observatory for Mapping the Galaxy
Chihway Chang, Christian Monstein, Joel Akeret +5
We describe the design and performance of the hardware system at the Bleien Observatory. The system is designed to deliver a map of the Galaxy for studying the foreground contamina…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
The GPU-based High-order adaptive OpticS Testbench
Byron Engler, Markus Kasper, Serban Leveratto +12
The GPU-based High-order adaptive OpticS Testbench (GHOST) at the European Southern Observatory (ESO) is a new 2-stage extreme adaptive optics (XAO) testbench at ESO. The GHOST is…
