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…
GA-NIFS: Understanding the ionization nature of EGSY8p7/CEERS-1019. Evidence for a star formation-driven outflow at z = 8.6
Sandra Zamora, Stefano Carniani, Elena Bertola +16
Understanding the physical conditions and feedback mechanisms in early massive galaxies is essential to uncover how they formed and evolved during the first billion years of the Un…
High-Redshift Galactic Outflows: Orientation Effects, Kinematics, and Metallicity in TNG50 and SERRA
Ivan Kostyuk, Stefano Carniani, Mahsa Kohandel +1
Context: Recently, JWST/NIRSpec observations have provided the first detections of warm ionised outflows in low-mass galaxies at high redshifts (z>3), revealing an occurrence rate…
