BlackTHUNDER Reveals a Massive Filament around a Compact AGN at

Giulia Tozzi, Hannah Übler, Eleonora Parlanti +27

Despite the growing number of compact active galactic nuclei (AGN) at discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the…

Little Red and Blue Dots: AGN-excited narrow lines, Lyman- emission, and resemblance to standard quasars

Sophia Geris, Roberto Maiolino, Xihan Ji +35

We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at , identified by JWST in the GOODS fields. While both categories are selected to ha…

JADES: the mass-metallicity relation at . New calibrations, extremely metal-poor galaxies, and chemical diversity

Yuki Isobe, Mirko Curti, Roberto Maiolino +28

We present gas-phase metallicities of star-forming galaxies at -10 with deep JWST/NIRSpec spectra from the JADES full data release, Dark Horse, and OASIS programmes. We stack…

BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy

Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41

We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…

JADES Data Release 4 Paper I: Sample Selection, Observing Strategy and Redshifts of the complete spectroscopic sample

Emma Curtis-Lake, Alex J. Cameron, Andrew J. Bunker +34

This paper accompanies Data Release 4 of the JWST Deep Extragalactic Survey (JADES), which presents the full NIRSpec spectroscopy of the survey. We provide spectra of 5190 targets…

Intense and extended CIII] emission suggests a strong outflow in JADES-GS-z14-0

Stefano Carniani, Peter Jakobsen, Giacomo Venturi +31

JWST has revealed an overabundance of very bright, blue galaxies at z>10, raising fundamental questions about how star formation and feedback operate at Cosmic Dawn. We present new…
