Effects of the Hunga Tonga-Hunga Ha'apai Volcanic Eruption on Observations at Paranal Observatory
Robert J. De Rosa, Angel Otarola, Thomas Szeifert +8
The Hunga Tonga-Hunga Ha'apai volcano erupted on 15 January 2022 with an energy equivalent to around 61 megatons of TNT. The explosion was bigger than any other volcanic eruption s…
CRIRES on sky at the ESO Very Large Telescope
R. J. Dorn, P. Bristow, J. V. Smoker +49
The CRyogenic InfraRed Echelle Spectrograph (CRIRES) Upgrade project CRIRES extended the capabilities of CRIRES. It transformed this VLT instrument into a cross-dispersed spe…
Nowcasting the turbulence at the Paranal Observatory
J. Milli, R. Gonzalez, P. R. Fluxa +13
At Paranal Observatory, the least predictable parameter affecting the short-term scheduling of astronomical observations is the optical turbulence, especially the seeing, coherence…
Raman-scattered laser guide star photons to monitor the scatter of astronomical telescope mirrors
F. P. A. Vogt, J. L. Álvarez, D. Bonaccini Calia +26
The first observations of laser guide star photons Raman-scattered by air molecules above the Very Large Telescope (VLT) were reported in June 2017. The initial detection came from…
Regaining the FORS: making optical ground-based transmission spectroscopy of exoplanets with VLT+FORS2 possible again
Henri M. J. Boffin, Elyar Sedaghati, Guillaume Blanchard +10
Transmission spectroscopy facilitates the detection of molecules and/or clouds in the atmospheres of exoplanets. Such studies rely heavily on space-based or large ground-based obse…
Concept and optical design of the cross-disperser module for CRIRES+
E. Oliva, A. Tozzi, D. Ferruzzi +31
CRIRES, the ESO high resolution infrared spectrometer, is a unique instrument which allows astronomers to access a parameter space which up to now was largely uncharted. In its cur…
