BL Lac host galaxies: how to systematically characterise them in optical-NIR spectroscopy
Gaia Delucchi, Tullia Sbarrato, Giorgio Calderone +3
Host galaxies of Active Galactic Nuclei give crucial information on the interaction between accreting Supermassive Black Holes and their surroundings, and on their common evolution…
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…
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…
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…
