High-ionization coronal lines trace quasar-like activity in recently quenched galaxies at high redshift
F. Valentino, K. Ito, M. Farcy +31
We report the detection of the high-ionization line [NeV]3427 in the JWST/NIRSpec archival spectra of 6 massive quenched galaxies at , identified from a parent…
First Light and Reionization Epoch Simulations (FLARES) XXII: UV-dust spatial offsets at the Epoch of Reionisation
Paurush Punyasheel, Aswin P. Vijayan, William J. Roper +8
Recent observations have revealed intriguing offsets between the UV and FIR emission in high redshift galaxies. In this study, we use the First Light And Reionisation Epoch Simulat…
The ALPINE-CRISTAL-JWST Survey: Gas-phase abundance gradients of main sequence star-forming galaxies and their kinematics at
Lilian L. Lee, Natascha M. Förster Schreiber, Seiji Fujimoto +50
We present gas-phase radial metallicity profiles for 20 main-sequence galaxies at , primarily based on JWST NIRSpec IFU observations obtained as part of the JWST-ALPINE-CRIS…
Spatially resolved metallicity and ionization in the merging system Gz9p3 at z=9.3
Arjan Bik, Javier Ãlvarez-Márquez, Alejandro Crespo Gómez +26
Studying the interstellar medium (ISM) in merging high-redshift galaxies is crucial for understanding early galaxy assembly, star formation, and black hole growth, predicted by hie…
Extending the ALMA survey of the SCUBA-2 CLS UDS field: Tracing the obscured formation of spheroids across z~1-4
Ian Smail, Steven Gillman, Ugne Dudzeviciute +1
We investigate the properties of 870-um selected galaxies at z~1-4 with FIR luminosities of LIR~1e11-1e13Lo, encompassing systems that dominate obscured activity at the peak of cos…
The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities
Steven Gillman, Kei Ito, Francesco Valentino +24
We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-…
