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…
A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase
Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12
We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…
The impact of hot mode accretion and angular momentum conservation on metallicity gradients of galactic discs
Jennifer K. S. Friske, Filippo Fraternali, Gabriele Pezzulli
The hot circumgalactic medium (CGM) of a galaxy inevitably rotates more slowly than the cold gas in the disc it surrounds, due to a higher pressure support against gravity. If it a…
Misaligned or chaotic? A strong break of axial symmetry in the local LRD J1025 revealed with VLT/FORS2 spectropolarimetry
Francesco D'Eugenio, Gabriele Pezzulli, Roberto Maiolino +18
Little Red Dots (LRDs) are compact active galactic nuclei (AGN) with unusual spectral energy distributions and broad Balmer emission, candidate signposts of rapid black-hole growth…
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…
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…
The assembly and fate of a giant disc galaxy in a protocluster at
Francesca Rizzo, Pavel E. Mancera Piña, Gabriele Pezzulli +1
Recent JWST observations revealed two massive (), unexpectedly large spiral galaxies at , both in overdense environments. We focus o…
Holes in the BH? AGN signatures in the FUV spectrum of a black-hole dominated Little Red Dot at
Xihan Ji, Gabriele Pezzulli, Francesco D'Eugenio +15
It has been suggested that "Little Red Dots" (LRDs) might be accreting black holes enshrouded by dense gas in a nearly closed geometry, which completely covers the central black ho…
The Engine and its Flows: Little Red Dot spectra are shaped by the column densities of their gas envelopes
Jorryt Matthee, Alberto Torralba, Gabriele Pezzulli +23
JWST data have enabled the abundant identification of compact broad Balmer line sources nicknamed the Little Red Dots. While they share broad lines with active galactic nuclei, the…
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…
