ReveaLLAGN 0: JWST MIRI obs. of NGC4594 and NGC1052
Listed in IVOA Registry (Virtual Observatory)
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGNs.
Description
We focus on two observations with the Mid-Infrared Instrument (MIRI)'s Medium-Resolution Spectrometer of the nuclei of NGC 1052 and Sombrero (NGC 4594/M104). We also compare these data to public JWST data of higher-luminosity AGNs, NGC 7319 and NGC 7469.
JWST clearly separates the AGN spectrum from the galaxy light even in Sombrero, the faintest target in our survey; the AGN components have very red spectra. We find that the emission-line widths in both NGC 1052 and Sombrero increase with increasing ionization potential, with FWHM>1000km/s for lines with ionization potential >~50eV. These lines are also significantly blueshifted in both LLAGNs.

The high-ionization-potential lines in NGC 7319 show neither broad widths nor significant blueshifts. Many of the lower-ionization-potential emission lines in Sombrero show significant blue wings extending >1000km/s. These features and the emission-line maps in both galaxies are consistent with outflows along the jet direction.
Sombrero has the lowest-luminosity high-ionization-potential lines ([NeV] and [OIV]) ever measured in the mid-infrared, but the relative strengths of these lines are consistent with higher-luminosity AGNs. On the other hand, the [NeV] emission is much weaker relative to the [NeIII] and [NeII] lines of higher-luminosity AGNs. These initial results show the great promise that JWST holds for identifying and studying the physical nature of LLAGNs.
