Stellar- and AGN-Driven Outflows in JWST Galaxies at z=3-9: More Frequent, Wider Opening Angles, and Mostly Bounded

Understand

We study outflows in 130 galaxies with -22<MUV<-16 at z=3-9 identified in JWST NIRSpec and NIRCam WFSS data taken by the ERO, CEERS, FRESCO, GLASS, and JADES programs.

• We identify 30 out of the 130 galaxies with broad components of FWHM~200-700 km s$^{-1}$ in the emission lines of H${\alpha}$ and [OIII] that trace ionized outflows, and find no excesses from the star-formation main sequence.
• Four out of the 30 outflowing galaxies are Type-1 AGN whose H${\alpha}$ emission lines include line profile components as broad as FWHM>1000 km s$^{-1}$ while one galaxy is identified as a Type-2 AGN by high ionization emission lines.
• With the velocity shift and line widths of the outflow broad lines, we obtain ~80-500 km s$^{-1}$ for the outflow velocities.
