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…
Unveiling the Cosmic Dawn with SHARP: Probing extended Lyman- nebulae in a Universe less than 600 Myr old
Susanna Bisogni, Giustina Vietri, Enrico Piconcelli +5
The existence of luminous quasars just a few hundred million years after the Big Bang challenges our understanding of both black hole growth and galaxy formation and evolution. The…
AGN Feedback: The impact of galactic-scale radio jets on the interstellar medium in starbursting obscured AGN
M. Polletta, C. J. Lonsdale, P. Pallavi +3
A highly star-forming galaxy at z ~ 2 hosting an obscured, luminous active galactic nucleus (AGN) and a relativistic radio jet sets the stage for a cosmic crime scene. The victim i…
SUNRISE-3D: Sharp UNveiling of AGN feedback Regulation and its Impact on Star-formation at the cosmic noon Epoch
G. Vietri, S. Bisogni, E. Piconcelli +4
To better understand the role of AGN-driven outflows as a mechanism for heating or sweeping up gas over distances comparable to the size of the galaxy in its evolution, and to expl…
A SHARP Look at Quenching and Bulge-Disk Growth in Massive Galaxies at Cosmic Noon
Chiara Mancini, Adriana Gargiulo, Alvio Renzini +11
The physical mechanisms that quench star formation in massive galaxies remain poorly understood. At cosmic noon (1<z<3), when star formation and AGN activity peak, galaxies rapidly…
