Feeding the Dead: Neutral Gas Inflow in a Long-quenched Ancient Massive Galaxy at z ∼ 2.7 Observed with JWST/NIRSpec

We report the spectroscopic detection of neutral gas inflow into a massive ( M _*  ≃ 4 × 10 ^10 M _⊙ ) quiescent galaxy observed at z _spec  = 2.6576 with the James Webb Space Telescope (JWST). From the redshifted absorption of the Na I doublet at λλ 5890, 5896, we estimate an inflow velocity $v=27{...
