An upper limit on [OIII] 88 $\mu$m and 1.2 mm continuum emission from a JWST $z \approx 12-13$ galaxy candidate with ALMA

Understand

A number of new $z>11$ galaxy candidates have recently been identified based on public James Webb Space Telescope (JWST) NIRCam observations.

• Spectroscopic confirmation of these candidates is necessary to robustly measure their redshift and put them in the context of our understanding of the buildup of galaxies in the early Universe.
• GLASS-z13 is one of these candidates, with a reported photometric redshift $z>11.9$.
• I present publicly available Atacama Large Millimeter/submillimeter Array (ALMA) band 6 Director's Discretionary Time observations (project 2021.A.00020.S; PI T.
