BEACON: JWST NIRCam Pure-parallel Imaging Survey. II. Physical Properties of Galaxies

Yechi Zhang, Takahiro Morishita, Kimi C. Kreilgaard +23

We present photometric properties of 161 galaxy candidates at selected from the second data release (DR2) of BEACON, a JWST Cycle 2 pure-parallel NIRCam imaging program. C…

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…

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…

What can we learn from the Nitrogen abundance of High-z galaxies?

Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +9

We present measurements of the gas-phase Oxygen and Nitrogen abundances obtained by applying the direct method to JWST NIRspec spectroscopy for 6 galaxies at redshift g…

BEACON: JWST NIRCam Pure-parallel Imaging Survey. I. Survey Design and Initial Results

Takahiro Morishita, Charlotte A. Mason, Kimi C. Kreilgaard +32

We introduce the Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON) survey, a JWST Cycle2 program allocated up to 600 pure-parallel hours of observations. BEA…
