ALMA Observation of a z ≳ 10 Galaxy Candidate Discovered with JWST

We report the ALMA observation of a $z\gtrsim10$ galaxy candidate (GHZ1) discovered from GLASS-JWST Early Release Science Program. Our program aims to detect [OIII] emission line at rest-frame 3393.0062 GHz ($88.36\mu$m) and far-IR continuum with spectral window setup seamlessly covering 26.125 frequency range ($10.10<z<11.14$). A total 7 hours on-source integration was employed, using four settings cover full (1.7 per setting), $0''.7$ angular resolution. No or is clearly detected, 5$\sigma$ upper limit 0.93 mJy beam$^{-1}$ 25 km s$^{-1}$ channel$^{-1}$ 30$\mu$Jy beam$^{-1}$. marginal (at 225 resolution) features ($4.1\sigma$ $2.6\sigma$ peak signal-to-noise ratio, respectively), within $0''.17$ JWST position GHZ1. This feature implies $z=10.38$ needs be verified further observations. Assuming that best photometric redshift estimate ($z=10.60^{+0.52}_{-0.60}$) correct, broadband energy distribution model for $3\sigma$ flux GHZ1 suggests has small amount dust ($M_d\lesssim10^4 M_{\odot}$) high temperature ($T_d\gtrsim90$K). The $5\sigma$ [OIII]$_{88\mu m}$ luminosity inferred star formation rate consistent properties low metallicity dwarf galaxies. also serendipitous clear detections six sources locations counterparts in field.
