Characterization of the K2-38 planetary system. Unraveling one of the densest planets known to date
B. Toledo-Padrón, C. Lovis, A. Suárez Mascareño +90
We characterized the transiting planetary system orbiting the G2V star K2-38 using the new-generation echelle spectrograph ESPRESSO. We carried out a photometric analysis of the av…
A precise architecture characterization of the Men planetary system
M. Damasso, A. Sozzetti, C. Lovis +97
The bright star Men was chosen as the first target for a radial velocity follow-up to test the performance of ESPRESSO, the new high-resolution spectrograph at the ESO's Very-…
MACAO-CRIRES, a step towards high-resolution spectroscopy
J. Paufique, P. Biereichel, R. Donaldson +14
High resolution spectroscopy made an important step ahead 10 years ago, leading for example to the discovery of numerous exoplanets. But the IR did not benefit from this improvemen…
ESPRESSO@VLT -- On-sky performance and first results
F. Pepe, S. Cristiani, R. Rebolo +97
ESPRESSO is the new high-resolution spectrograph of ESO's Very-Large Telescope (VLT). It was designed for ultra-high radial-velocity precision and extreme spectral fidelity with th…
Challenges in optics for Extremely Large Telescope instrumentation
P. Spanò, F. M. Zerbi, C. J. Norrie +15
We describe and summarize the optical challenges for future instrumentation for Extremely Large Telescopes (ELTs). Knowing the complex instrumental requirements is crucial for the…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
The ESO Spectroscopic facility
Luca Pasquini, B. Delabre, R. S. Ellis +3
We present the concept of a novel facility dedicated to massively-multiplexed spectroscopy. The telescope has a very wide field Cassegrain focus optimised for fibre feeding. With a…
SINFONI - Integral Field Spectroscopy at 50 milli-arcsecond resolution with the ESO VLT
F. Eisenhauer, H. Bonnet, R. Abuter +21
SINFONI is an adaptive optics assisted near-infrared integral field spectrometer for the ESO VLT. The Adaptive Optics Module (built by the ESO Adaptive Optics Group) is a 60-elemen…
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…
The CODEX-ESPRESSO experiment: cosmic dynamics, fundamental physics, planets and much more..
S. Cristiani, G. Avila, P. Bonifacio +36
CODEX, a high resolution, super-stable spectrograph to be fed by the E-ELT, the most powerful telescope ever conceived, will for the first time provide the possibility of directly…
On-sky results of the adaptive optics MACAO for the new IR-spectrograph CRIRES at VLT
J. Paufique, P. Biereichel, B. Delabre +16
The adaptive optics MACAO has been implemented in 6 focii of the VLT observatory, in three different flavors. We present in this paper the results obtained during the commissioning…
ESPRESSO: The next European exoplanet hunter
F. Pepe, P. Molaro, S. Cristiani +55
The acronym ESPRESSO stems for Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations; this instrument will be the next VLT high resolution spectrograph. T…
Tachoastrometry: astrometry with radial velocities
L. Pasquini, C. Cortés, M. Lombardi +3
Spectra of composite systems (e.g., spectroscopic binaries) contain spatial information that can be retrieved by measuring the radial velocities (i.e., Doppler shifts) of the compo…
Revisiting Proxima with ESPRESSO
A. Suárez Mascareño, J. P. Faria, P. Figueira +88
We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…
Probing unexplored territories with MUSE: a second generation instrument for the VLT
R. Bacon, S. Bauer, P. Boehm +57

New telescope designs suitable for massively-multiplexed spectroscopy
L. Pasquini, B. Delabre, R. Ellis +1
We present two novel designs for a telescope suitable for massively-multiplexed spectroscopy. The first is a very wide field Cassegrain telescope optimised for fibre feeding. It pr…
Cosmic dynamics in the era of Extremely Large Telescopes
J. Liske, A. Grazian, E. Vanzella +24
