"Perfect" spectra for ESO's HARPS spectrograph
Dinko Milaković, Guido Cupani, Bruce A. Bassett +2
HARPERFECT is the first application of "spectral perfectionism" to a high-resolution echelle spectrograph, reconstructing 1D spectra from 2D detector data via a forward model built…
Test of a 34 GHz EOM laser frequency comb at ESPRESSO
Tobias M. Schmidt, Ewelina Obrzud, François Bouchy +18
Laser frequency combs (LFCs) are a promising technology for wavelength calibration of astronomical high-resolution spectrographs requiring utmost accuracy and stability, since they…
The ESPRESSO Redshift Drift Experiment III -- The Third Epoch of QSO J052915.80-435152.0
Andrea Trost, Catarina M. J. Marques, S. Cristiani +25
The Sandage-Loeb test probes cosmic expansion directly by measuring the redshift drift in quasar absorption features in a model-independent way. In this series of papers, we have l…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period
Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148
We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…
From the Intergalactic to the Interstellar Scales -- EQUALS: a High-resolution Legacy Survey of Gas in the Distant Universe Using ESPRESSO
Trystyn Berg, Valentina D'Odorico, Elisa Boera +14
Understanding how the Universe evolved from diffuse primordial gas into the rich cosmic web we observe today is one of the great challenges of modern astrophysics. Quasar absorptio…
Quantifying thermal water dissociation in the dayside photosphere of WASP-121 b using NIRPS
Luc Bazinet, Romain Allart, Björn Benneke +119
The intense stellar irradiation of ultra-hot Jupiters results in some of the most extreme atmospheric environments in the planetary regime. On their daysides, temperatures can be s…
NIRPS joining HARPS at ESO 3.6 m. On-sky performance and science objectives
Francois Bouchy, Rene Doyon, Francesco Pepe +131
The Near-InfraRed Planet Searcher (NIRPS) is a high-resolution, high-stability near-infrared (NIR) spectrograph equipped with an AO system. Installed on the ESO 3.6-m telescope, it…
Diving into the planetary system of Proxima with NIRPS -- Breaking the metre per second barrier in the infrared
Alejandro Suárez Mascareño, Étienne Artigau, Lucile Mignon +138
We obtained 420 high-resolution spectra of Proxima, over 159 nights, using the Near Infra Red Planet Searcher (NIRPS). We derived 149 nightly binned radial velocity measurements wi…
NIRPS detection of delayed atmospheric escape from the warm and misaligned Saturn-mass exoplanet WASP-69b
Romain Allart, Yann Carteret, Vincent Bourrier +119
Near-infrared high-resolution echelle spectrographs unlock access to fundamental properties of exoplanets, from their atmospheric escape and composition to their orbital architectu…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
The ESPRESSO Redshift Drift Experiment I -- High-resolution spectra of the Lyman- forest of QSO J052915.80-435152.0
Andrea Trost, Catarina M. J. Marques, Stefano Cristiani +25
The measurement of the temporal evolution in the redshift of distant objects, the redshift drift, is a probe of universal expansion and cosmology. We perform the first steps toward…
