Estimating the completeness of the QUBRICS Survey with 3501 QSO redshifts from Gaia DR3 spectra
Matteo Porru, Stefano Cristiani, Francesco Guarneri +9
QSOs are essential for investigating the structure and evolution of the Universe. Historically, their identification has been concentrated in the northern hemisphere, primarily due…
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…
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…
CUBES, the Cassegrain U-Band Efficient Spectrograph: towards final design review
Matteo Genoni, Hans Dekker, Stefano Covino +39
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…
