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…

JWST Lensed Quasar Dark Matter Survey III: Dark Matter Sensitive Flux Ratios and Warm Dark Matter Constraint from the Full Sample

R. E. Keeley, A. M. Nierenberg, D. Gilman +24

We present the full sample of measurements of the warm dust emission of 31 strongly-lensed, multiply imaged quasars, observed with JWST MIRI multiband imaging, which we use to cons…

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…

TDCOSMO 2025: Cosmological constraints from strong lensing time delays

TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30

We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…

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…

Metallicity Scatter Originating from Sub-kiloparsec Starbursting Clumps in the Core of a Protocluster at z=7.88

Takahiro Morishita, Massimo Stiavelli, Eros Vanzella +9

We present new JWST NIRSpec integral field unit (IFU) G395H/F290LP observations of a merging galaxy system at , part of A2744-z7p9, the most distant protocluster to date. T…
