Probing neutral outflows in z  ∼  2 galaxies using JWST observations of Ca II H and K absorption lines

Using deep JWST/NIRSpec spectra from the Blue Jay survey, we performed the first systematic investigation of neutral gas content in massive galaxies at Cosmic Noon based on the Ca II H, K absorption lines. We analyzed a sample of nine galaxies at 1.8 < z < 2.8 with log M*/M⊙ > 10.6, for which we det...
