Ionizing Photon Production Efficiencies and Chemical Abundances at Cosmic Dawn Revealed by Ultra-Deep Rest-Frame Optical Spectroscopy of JADES-GS-z14-0
Jakob M. Helton, Jane E. Morrison, Kevin N. Hainline +40
JWST has discovered an early period of galaxy formation that was more vigorous than expected, which has challenged our understanding of the early Universe. In this work, we present…
The accretion of quasars at the epoch of reionisation: catches the primeval monsters slowly feasting
B. Trefoloni, E. Nardini, S. Carniani +8
Quasars (QSOs) emit an enormous amount of light as a result of the accretion of gas onto supermassive black holes (SMBHs). Thanks to their luminosity, the most distant known QSOs a…
GA-NIFS: the highest-redshift ring galaxy candidate from a head-on collision
Michele Perna, Santiago Arribas, Luca Costantin +18
Collisional ring galaxies are a rare class of interacting systems, making up only ~0.01% of galaxies in the local Universe. Their formation is typically attributed to a head-on col…
Signatures of star formation inside galactic outflows
Dily Duan Yi Ong, Francesco D'Eugenio, Roberto Maiolino +13
Observations have suggested that galactic outflows contain substantial amounts of dense and clumpy molecular gas, creating favourable conditions for igniting star formation. Indeed…

Probing Infrared eXcess to Investigate Early-Universe Dust (PIXIEDust)
Tom J. L. C. Bakx, Hiddo S. B. Algera, Jean-Baptiste Jolly +25
Despite the implied presence of dust through reddened UV emission in high-redshift galaxies, no dust emission has been detected in the (sub)millimetre regime beyond . This…
Doubling NIRSpec/IFS capability to calibrate the single-epoch black hole mass relation at high redshifts
Eleonora Parlanti, Bartolomeo Trefoloni, Stefano Carniani +6
The recent discovery of a large population of overmassive black holes (BHs) in the early Universe challenges the validity of the BH-host galaxy coevolution framework. However, the…
Cosmic Duets I. High-spatial resolution spectroscopy of dual and lensed AGN with MUSE-NFM
M. Scialpi, F. Mannucci, Q. D'Amato +34
We present the first-year results of the MUSE Large Program "Cosmic Duets", whose goal is to obtain adaptive-optics assisted MUSE observations with an angular resolution of 0.1"-0.…
GA-NIFS: Powerful and frequent outflows in moderate-luminosity active galactic nuclei at
Giacomo Venturi, Stefano Carniani, Elena Bertola +18
The period between z ~ 3-6, a key transformational phase in galaxy evolution preceding 'cosmic noon' (z ~ 1-3), is very poorly explored in terms of feedback from AGN acting through…
A warm ultra-luminous infrared galaxy just 600 million years after the Big Bang
T. J. L. C. Bakx, Laura Sommovigo, Yoichi Tamura +24
We present an Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 continuum detection () of MACS0416_Y1 that confirms the suspected warm dust (91 K) of…
A deep X-ray look to the most obscured quasar at z~3.6 and its environment
I. Villani, L. Zappacosta, E. Piconcelli +17
The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…
Mergers lighting the early Universe: modest star formation enhancement without evidence for AGN or Ly triggering
Dávid Puskás, Sandro Tacchella, Charlotte Simmonds +16
Galaxy mergers and interactions are often invoked to explain enhanced star formation, black hole growth, and mass build-up of galaxies at later cosmic times, but their effect is po…
Possible photometric signatures of nebular-dominated emission in JADES galaxies
James A. A. Trussler, Alex J. Cameron, Daniel J. Eisenstein +21
The discovery of high-redshift galaxies exhibiting a steep spectral UV downturn potentially indicative of two-photon continuum emission marks a turning point in our search for sign…
Beyond the stars: Linking H sizes, kinematics, and star formation in galaxies at with JWST grism surveys and
A. Lola Danhaive, Sandro Tacchella, William McClymont +15
Understanding how galaxies assemble their mass during the first billion years of cosmic time is a central goal of extragalactic astrophysics, yet joint constraints on their sizes a…
