Reionization in Protocluster Environments at with JWST/NIRSpec
Qiong Li, Christopher J. Conselice, Duncan Austin +4
Understanding the role of high-redshift protoclusters in cosmic reionization is essential to unveiling the early stages of structure formation. Using deep imaging and spectroscopy…
Probing the origin of the kilonova candidate GRB 230307A: analysis of host galaxy and offset
Clecio R. Bom, Davi C. Rodrigues, Arianna Cortesi +12
We investigate the host galaxy of the long gamma-ray burst GRB 230307A, which is associated with a kilonova candidate likely produced by a binary neutron-star (BNS) merger. The tra…
Galaxy-scale lens search in the PEARLS NEP TDF and CEERS JWST fields
Giovanni Ferrami, Nathan J. Adams, Lewi Westcott +14
We present four galaxy scale lenses discovered in two JWST blank-fields: the ~ 54 arcmin^2 of the PEARLS North-Ecliptic-Pole Time-Domain Field (NEP TDF) and in the ~ 90 arcmin^2 of…
A nuclear disc at Cosmic Noon: evidence of early bar-driven galaxy evolution
Zoe A. Le Conte, Dimitri A. Gadotti, Thomas Harvey +7
Recent studies have revealed that bars can form as early as a few billion years after the Big Bang, already displaying characteristics similar to those of evolved bars in the Local…
Resolving the ionizing photon budget crisis with JWST/NIRCam HII clumping constraints at z=6
Duncan Austin, Thomas Harvey, Christopher J. Conselice +18
We present a comprehensive study of the ionizing properties of 1721 galaxies at using deep JWST/NIRCam photometric imaging from the NEP, JADES, and PRIMER surveys spann…
Dissecting Reionisation with the Cosmic Star Formation and Active Galactic Nuclei Luminosity History
Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +23
The combination of the cosmic star formation history and active galactic nuclei (AGN) luminosity history as inferred by the James Webb Space Telescope is connected to th…
