We observed the Seyfert 1 galaxy NGC 4593 with the Chandra high-energy transmission gratings and present a detailed analysis of the soft X-ray spectrum. We measure strong absorption lines from He-like O, Ne, Mg, Si, H-like N, O, Ne, Mg, Si, and highly ionized Fe XIX-Fe XXV. The weighted mean of the offset velocity of the strongest absorption profiles is -140 ± 35 km s-1. However, the individual profiles are consistent with the systemic velocity of NGC 4593, and many profiles hint at the…
