Data pubblicazione: | 2018 | Rivista: | THE ASTROPHYSICAL JOURNAL LETTERS | Numero: | 866 | Fascicolo: | 1 | Da pagina:: | L9 | Abstract: | We report spatially resolved [C II] λ158 μm observations of HE 0433-1028, which is the first detection of a nearby luminous active galactic nucleus (AGN; redshift 0.0355) with the Field-Imaging Far-Infrared Line Spectrometer (FIFI-LS) on board the airborne Stratospheric Observatory For Infrared Astronomy (SOFIA). We compare the spatially resolved star formation tracers [C II], as provided by our SOFIA observations, and Hα from the Multi Unit Spectroscopic Explorer (MUSE) optical integral-field spectroscopy. We find that the [C II] emission is mainly matching the extended star formation as traced by the extinction-corrected Hα line emission but some additional flux is present. While a larger sample is needed to statistically confirm our findings and investigate possible dependencies on AGN luminosity and star formation rate, our study underlines the necessity of collecting a spatially resolved optical-far-infrared data set for nearby AGNs, and shows that it is technically feasible to collect such data sets with FIFI-LS on board SOFIA. | URI: | http://hdl.handle.net/20.500.12386/29234 | URL: | https://iopscience.iop.org/article/10.3847/2041-8213/aae25d | ISSN: | 2041-8205 | DOI: | 10.3847/2041-8213/aae25d | Bibcode ADS: | 2018ApJ...866L...9B | Fulltext: | open |
