Sleeping or Dead? Probing the Quenching Mechanism of JWST Dormant Galaxies at z > 3 with ALMA
Mengyuan Xiao, Songnan Qi, Pascal A. Oesch +16
JWST has revealed a population of "dormant'' galaxies at z>3 with strong Balmer breaks and weak emission lines, whose star formation appears to have declined only recently. Whether…

Search for High-Ionization Nebular Emission (SHINE). I. A Systematically Selected [Ne V] Sample at z > 3 with JWST/NIRSpec PRISM
Shobita Satyapal, Sara Doan, Daniel Schaerer +8
We conduct the first systematic Search for High-Ionization Nebular Emission (SHINE) using [Ne V] in JWST/NIRSpec PRISM spectroscopy at . From more than 9,000 gala…

A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26
Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…
