Ionized gaz outflows in AKARI local ULIRGs
Listed in IVOA Registry (Virtual Observatory)
We explore the properties of stellar kinematics and ionized gas in a sample of 1106 local (U)LIRGs from the AKARI telescope.
Description
We combine data from Wide-field Infrared Survey Explorer and Sloan Digital Sky Survey Data Release 13 to fit the spectral energy distribution (SED) of each source to constrain the contribution of active galactic nuclei (AGNs) to the total IR luminosity and estimate physical parameters such as stellar mass and star formation rate (SFR).
We split our sample into AGNs and weak/non-AGNs. We find that our sample is considerably above the main sequence. The highest SFRs and stellar masses are associated with ULIRGs.

We also fit the H{beta} and H{alpha} regions to characterize the outflows. We find that the incidence of ionized gas outflows in AGN (U)LIRGs (~72%) is much higher than that in weak/non- AGN ones (~39%). The AGN ULIRGs have extreme outflow velocities (up to ~2300km/s) and high mass-outflow rates (up to ~60M_{sun}_/yr).
Our results suggest that starbursts are insufficient to produce such powerful outflows. We explore the correlations of SFR and specific SFR (sSFR) with ionized gas outflows. We find that AGN hosts with the highest SFRs exhibit a negative correlation between outflow velocity and sSFR.
Therefore, in AGNs containing large amounts of gas, the negative feedback scenario might be suggested.
