DOI: 10.1093/mnras/stad1014

Abstract: We have derived luminosity functions, and set constraints on the UV luminosity and SFR density from z ∼ 17 to z ∼ 8, using the three most-studied JWST/NIRCam data sets, the SMACS0723, GLASS Parallel, and… read more here.

DOI: 10.1093/mnras/stad1408

Abstract: We present an interstellar medium and stellar population analysis of three spectroscopically confirmed z > 7 galaxies in the ERO JWST/NIRCam and JWST/NIRSpec data of the SMACS J0723.3-7327 cluster. We use the Bayesian spectral energy… read more here.

DOI: 10.1093/mnras/stae1891

Abstract: Combining the public JWST/NIRCam imaging programs CEERS, PRIMER and JADES, spanning a total area of ∼500 arcmin2, we obtain a sample of >30,000 galaxies at zphot ∼ 4 − 9 that allows us to perform a… read more here.

DOI: 10.1093/mnras/staf031

Abstract: Resolved stellar morphology of z > 1 galaxies was inaccessible before JWST. This limitation, due to the impact of dust on rest-frame UV light, had withheld major observational conclusions required to understand the importance of… read more here.
