spelling Extended high-ionization [Mg iv] emission tracing widespread shocks in starbursts seen by JWST/NIRSpecPereira-Santaella, MiguelGarcía-Bernete, I.González-Alfonso, E.Alonso-Herrero, A.Colina, L.García-Burillo, SantiagoRigopoulou, D.Arribas-Mocoroa, SantiagoPerna, M.Galaxies: activeGalaxies: evolutionGalaxies: starburstInfrared: ISM15 pags., 16 figs., 1 tab.We report the detection of extended (>0.5–1 kpc) high-ionization [Mg iv] 4.487 µm (80 eV) emission in four local luminous infrared galaxies observed with JWST/NIRSpec. Excluding the nucleus and outflow of the Type 1 active galactic nucleus (AGN) in the sample, we find that the [Mg iv] luminosity is well correlated with that of H recombination lines, which mainly trace star-forming clumps in these objects, and that the [Ar vi] 4.530 µm (75 eV), usually seen in AGN, is undetected. On 100–400 pc scales, the [Mg iv] line profiles are broader (σ([Mg iv]) = 90 ± 25 km s) and shifted (∆v up to ±50 km s) compared to those of the H recombination lines and lower ionization transitions (e.g., σ(Hu-12) = 57 ± 15 km s). The [Mg iv] kinematics follow the large-scale rotating velocity field of these galaxies, and the broad [Mg iv] profiles are compatible with the broad wings detected in the H recombination lines. Based on these observational results, extended highly ionized gas more turbulent than the ambient interstellar medium, possibly a result of ionizing shocks associated with star formation, is the most likely origin of the [Mg iv] emission. We also computed new grids of photoionization and shock models to investigate where the [Mg iv] line originates. Shocks with velocities of 100–130 km s reproduce the observed line ratios and the [Mg iv] luminosity agrees with that expected from the mechanical energy released by supernove (SNe) in these regions. Therefore, these models support shocks induced by SNe as the origin of the [Mg iv] line. Future studies on the stellar feedback from SNe will benefit from the [Mg iv] line that is little affected by obscuration and, in the absence of an AGN, can only be produced by shocks due to its high ionization-potential.The authors acknowledge the GOALS ERS team for developing their observing program.
