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 dramatic transition of the extreme Red Supergiant WOH G64 to a Yellow Hypergiant
G. Munoz-Sanchez, M. Kalitsounaki, S. de Wit +8
Red Supergiants (RSGs) are cool, evolved massive stars in their final evolutionary stage before exploding as a supernova. However, the evolution and fate of the most luminous RSGs…
Chasing passive galaxies in the early Universe: a critical analysis in CANDELS GOODS-South
E. Merlin, A. Fontana, M. Castellano +12
We search for passive galaxies at in the GOODS-South field, using different techniques based on photometric data, and paying attention to develop methods that are sensitive t…
Variability-selected active galactic nuclei from supernova search in the Chandra deep field south
D. Trevese, K. Boutsia, F. Vagnetti +2
Variability is a property shared by virtually all active galactic nuclei (AGNs), and was adopted as a criterion for their selection using data from multi epoch surveys. Low Luminos…
Optical Spectroscopy of Active Galactic Nuclei in SA57
D. Trevese, V. Zitelli, F. Vagnetti +2
The cosmological evolution of X-ray-selected and optically selected Active Galactic Nuclei (AGNs) show different behaviours interpreted in terms of two different populations. The d…
