Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr

Roberta Tripodi, Nicholas Martis, Vladan Markov +29

The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…

Resolved mass assembly and star formation in Milky Way Progenitors since from JWST/CANUCS: From clumps and mergers to well-ordered disks

Vivian Yun Yan Tan, Adam Muzzin, Ghassan T. E. Sarrouh +17

We present a resolved study of 877 progenitors of Milky Way Analogs (MWAs) at selected with abundance matching in the ten fields of the Canadian NIRISS Unbiased Cluster S…

Molecular gas and dust properties in quasar hosts

Francesco Salvestrini, Chiara Feruglio, Roberta Tripodi +12

Observational campaigns hunting the elusive reservoirs of cold gas in the host galaxies of quasars at the epoch of reionization (EoR) are crucial for studying the formation and evo…

HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe

I. Saccheo, A. Bongiorno, E. Piconcelli +41

We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…

Multi-phase black-hole feedback and a bright [CII] halo in a Lo-BAL quasar at

Manuela Bischetti, Hyunseop Choi, Fabrizio Fiore +18

Although the mass growth of supermassive black holes during the Epoch of Reionisation is expected to play a role in shaping the concurrent growth of their host-galaxies, observatio…
