Planetary system around LTT 1445A unveiled by ESPRESSO: Multiple planets in a triple M-dwarf system
B. Lavie, F. Bouchy, C. Lovis +32
We present radial velocity follow-up obtained with ESPRESSO of the M-type star LTT 1445A (TOI-455), for which a transiting planet b with an orbital period of~5.4 days was detected…
The probabilistic random forest applied to the QUBRICS survey: improving the selection of high-redshift quasars with synthetic data
Francesco Guarneri, Giorgio Calderone, Stefano Cristiani +10
Several recent works have focused on the search for bright, high-z quasars (QSOs) in the South. Among them, the QUasars as BRIght beacons for Cosmology in the Southern hemisphere (…
The CUBES Science Case
Chris Evans, Stefano Cristiani, Cyrielle Opitom +51
We introduce the scientific motivations for the development of the Cassegrain U-Band Efficient Spectrograph (CUBES) that is now in construction for the Very Large Telescope. The as…
Automatic model-based telluric correction for the ESPRESSO data reduction software. Model description and application to radial velocity computation
R. Allart, C. Lovis, J. Faria +21
Ground-based high-resolution spectrographs are key instruments for several astrophysical domains. Unfortunately, the observed spectra are contaminated by the Earth's atmosphere. Wh…
CUBES, the Cassegrain U-Band Efficient Spectrograph
S. Cristiani, J. M. Alcalá, S. H. P. Alencar +74
In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at ground-UV wavelengths for the foreseeable future. The Casse…
The black hole and host galaxy growth in an isolated QSO observed with ALMA
R. Tripodi, C. Feruglio, F. Fiore +11
The outstanding mass growth of supermassive black holes (SMBHs) at the Reionisation Epoch and how it is related to the concurrent growth of their host galaxies, poses challenges to…
