JADES: A large population of obscured, narrow line AGN at high redshift

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jan Scholtz, Roberto Maiolino, Francesco D’Eugenio, Emma Curtis-Lake, Stefano Carniani | Summary: We present the identification of 42 narrow-line active galactic nuclei (type-2 AGN) candidates in the two deepest observations of the JADES spectroscopic survey with JWST/NIRSpec. The spectral coverage and the depth of our observations allow […]

Dynamics and spin alignment in massive, gravito-turbulent circumbinary discs around supermassive black hole binaries

Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin A. Bourne, Davide Fiacconi, Debora Sijacki, Joanna M. Piotrowska, Sophie Koudmani | Summary: Parsec-scale separation supermassive black hole binaries in the centre of gas-rich galaxy merger remnants could be surrounded by massive circumbinary discs (CBDs). Black hole mass and spin evolution during the gas-rich binary inspiral […]

Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Valentina D’Odorico, James S. Bolton, Lise Christensen, Annalisa De Cia, Erik Zackrisson | Summary: High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium and the reionisation of the Universe. However, these studies are […]

The galaxies missed by Hubble and ALMA: the contribution of extremely red galaxies to the cosmic census at 3<z<8

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Christina C. Williams, Stacey Alberts, Zhiyuan Ji, Kevin N. Hainline, Jianwei Lyu | Summary: Using deep JWST imaging from JADES, JEMS and SMILES, we characterize optically-faint and extremely red galaxies at $z>3$ that were previously missing from galaxy census estimates. The data indicate the existence of abundant, […]
