Constraining the density distribution of the cold Circumgalactic Medium of quasars at z>2 through Lya, HeII and Ha emission
Andrea Travascio, Sebastiano Cantalupo, Titouan Lazeyras +16
Extended Lya emission is routinely detected around high-redshift quasars, revealing large reservoirs of cool circumgalactic medium (CGM). Its resonant nature complicates interpreta…
Resolving the physics of Quasar Ly Nebulae (RePhyNe): II. The dense and clumpy CGM of Quasars at 3.5
Titouan Lazeyras, Sebastiano Cantalupo, Andrea Travascio +10
The small scale density distribution of the cold circumgalactic medium (CGM) plays a central role in galaxy evolution, yet it is still poorly understood. We provide new constraints…
Multi-tracer constraints on quasar outflows. Acceleration from BLR to galactic scales
M. Brazzini, M. Bischetti, S. Hagen +14
Black hole-driven outflows are a fundamental component of the Active Galactic Nuclei (AGN) paradigm, and may play a major role in regulating the evolution of both supermassive blac…
The Multiphase CGM in the Epoch of Reionization: CII and CIV absorbers around [OIII] Emitters
C. Piscitelli, V. D'Odorico, M. Galbiati +17
We investigate the multiphase circumgalactic medium (CGM) during the Epoch of Reionization (EoR, ) by cross-correlating cool- CII and warm-ionized CIV absorption systems with…
The WISSH quasars project XIII. A multi-epoch study of ultra-fast broad absorption line outflows at cosmic noon
A. Deconto-Machado, G. Vietri, E. Piconcelli +22
Ultra-fast broad absorption line outflows (uBAL, ~0.1-0.2c) represent some of the most extreme manifestations of quasar-driven winds. We aim to investigate the variability of uBALs…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
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…
The galaxy-halo connection and the dynamical evolution of a giant disc in a massive node of the Cosmic Web at z~3
G. Quadri, S. Cantalupo, C. Bacchini +9
Recent JWST observations revealed the surprising presence of a giant and massive disc galaxy in a Cosmic Web node at z. This galaxy, named the Big Wheel, has a size almost t…
A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at
Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +20
Gas flows between galaxies and the circumgalactic medium (CGM) play a central role in galaxy evolution and can become observable as giant nebulae when illuminated by the quasars. W…
The hydrodynamical response of cold circumgalactic clouds to quasar radiation
Nicolas Ledos, Sebastiano Cantalupo, Titouan Lazeyras +8
Recent simulations increasingly resolve the small-scale structure of the circumgalactic medium (CGM), but the dynamical impact of ionising radiation on its cold K component…
Resolving circumgalactic gas flows around a z3.6 quasar using MUSE and ALMA
M. Galbiati, A. Pensabene, S. Cantalupo +10
The formation and evolution of galaxies is regulated by the exchange of gas with the surrounding large-scale structures on circum- and intergalactic scales. Yet, little is known ab…
A quiescent galaxy in a gas-rich cosmic web node at z~3
Weichen Wang, Sebastiano Cantalupo, Marta Galbiati +11
Recent JWST observations have unveiled a large number of quiescent galaxies at , bringing potential challenges to current galaxy formation models. Since star formation i…
