[O III] Imaging of Narrow Line Region Outflows in Nearby Active Galaxies ("NLR-AGN")

The ionizing radiation generated by accreting supermassive black holes (SMBHs) can drive powerful outflows of gas that play a key role in galaxy evolution. These outflows are observed on a variety of spatial scales, including in the narrow line regions (NLRs) of AGN on scales of parsecs to kiloparsecs from the SMBH. These outflows can be accurately characterized using the high spatial-resolution imaging and spectroscopy afforded by HST. The team provides new [O III] and continuum images of 12 Seyfert galaxies with existing long-slit HST STIS spectra. The sample spans a moderate range in luminosity, black hole mass, and Eddington ratio, allowing the dependence of outflow parameters on AGN properties to be explored. These High Level Science Products increase the legacy value of the archival STIS spectra by providing matching [O III] images for NLR studies. The products include science images with plate scales of 0.04 arcsec/pixel with north up and east to the left.
