Little Red Dots are Direct-Collapse Black Hole-Forming Galaxies
Daniel J. Whalen, Muhammad A. Latif, Konstantinos Topalakis +3
"Little Red Dots" (LRDs) at are one of the most challenging discoveries by JWST to date because their distinctive V-shaped spectra and compact morphologies (100 - 200 p…
How Overmassive Black Holes Formed at Cosmic Dawn
Muhammad A. Latif, Daniel J. Whalen, Sadegh Khochfar +1
Overmassive black hole galaxies (OBGs) at redshifts 10, or 450 Myr after the Big Bang, are one of the most puzzling discoveries by the James Webb Space Telescope to date b…
Self-Consistent Direct Method for Chemical Abundances in High-z Galaxies with JWST
Karla Z. Arellano-Córdova, J. Eduardo Méndez-Delgado, Sophia R. Flury +10
The unprecedented rest-frame UV and optical coverage provided by JWST enables simultaneous constraints on the electron density (n) and temperature (T) of ionize…
PRIMER & JADES reveal an abundance of massive quiescent galaxies at 2 < z < 5
Struan D. Stevenson, Adam C. Carnall, Ho-Hin Leung +22
We select a mass-complete sample of 225 quiescent galaxies at with from PRIMER and JADES photometry spanning a total area of sq.…
MARTA: The connection between chemical enrichment, feedback, and dust in a Wolf-Rayet galaxy at z2
Mirko Curti, Elisa Cataldi, Francesco Belfiore +17
We present the analysis of the stellar and interstellar medium (ISM) properties of MARTA-4327, a star-forming galaxy at z=2.224 observed by means of deep JWST/NIRSpec spectroscopy…
A Metal-Free Galaxy at ? Evidence of Late Population III Star Formation at Cosmic Noon
Sijia Cai, Mingyu Li, Zheng Cai +10
Star formation from metal-free gas, the hallmark of the first generation of Population III stars, was long assumed to occur only in the very early Universe. We report the discovery…
Novel auroral line measurements extend the gradual offset of the FMR deep into the first Gyr of cosmic time
Clara L. Pollock, Rashmi Gottumukkala, Kasper E. Heintz +15
The mass assembly and chemical enrichment of the first galaxies provide key insights into their star-formation histories and the earliest stellar populations at cosmic dawn. Here w…
MARTA: Temperature-temperature relationships and strong-line metallicity calibrations from multiple auroral-line detections at cosmic noon
E. Cataldi, F. Belfiore, M. Curti +22
We present the first results from MARTA (Measuring Abundances at high Redshift with the T Approach), a programme leveraging ultra-deep, medium-resolution JWST/NIRSpec spectrosc…
