QUOTE {}In the currently available JWST data, this criterion is met by three galaxies in the Cycle 4 programme SPectroscopic Ultra-deep Reionization-era Survey (SPURS; PID 9214), all of which have rest-frame ultraviolet continuum detected near 1...
QUOTE {}At the spectral resolution of these data (R ≈ 1,000), the fitted profiles and measured EWs should be interpreted as effective, unresolved representations of potentially multiple narrow components.
QUOTE {}Velocity information alone does not uniquely distinguish between compact outflowing material and gas distributed over larger circumgalactic scales, as both scenarios can produce blueshifted absorption depending on geometry and driving me...
