Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars
Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20
The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…
Euclid: Discovery of 31 new quasars at
D. Yang, J. F. Hennawi, F. Guarneri +211
We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…
Euclid: A UV-faint quasar in a highly luminous star-forming host galaxy at
S. Belladitta, R. Decarli, E. Bañados +180
Constraining the co-evolution of supermassive black holes and their host galaxies in the first billion years after the Big Bang is essential for understanding the formation of the…
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…
