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…
