A Nitrogen-rich AGN Powering a Large Ionizing Bubble at z=8.63
Takahiro Morishita, Massimo Stiavelli, Charlotte A. Mason +5
We report the detection of Ly in CANUCS-LRD-z8.6, a recently discovered AGN at z = 8.63 by Tripodi et al. (2024), in new NIRSpec/MSA G140H/F070LP observations. We detect broad L…
Pristine Massive Star Formation Caught at the Break of Cosmic Dawn
Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +3
The existence of galaxies with no heavy elements is a key prediction of cosmological models. So far no "zero-metallicity", or Population~III, galaxies have been identified. Here, w…
The GLASS-JWST Early Release Science Programme: The NIRISS Spectroscopic Catalogue
Peter J. Watson, Benedetta Vulcani, Tommaso Treu +18
We present a spectroscopic redshift catalogue of sources in the Abell 2744 cluster field, derived from JWST/NIRISS observations taken as part of the GLASS-JWST Early Release Scienc…
Potential Nitrogen Enrichment via Direct-Collapse Wolf-Rayet Stars in a Star-Forming Galaxy
Yechi Zhang, Takahiro Morishita, Massimo Stiavelli
We present analyses of a nitrogen-enriched star-forming galaxy, ID60001, at based on JWST/NIRSpec MSA spectroscopy and NIRCam photometry. From rest-frame optical emissio…
