PI: Dr. Michael J Koss Eidgenossiche Technische Hochschule (ETH) Y CoI: Dr. Richard Mushotzky University of Maryland N CoI: Prof. Sylvain Veilleux University of Maryland N CoI: Dr. Ezequiel Treister Universidad de Concepcion N CoI: Prof. Kevin Schawinski Eidgenossiche Technische Hochschule (ETH) N CoI: Philipp Bernhard ETH Zurich N ------------------------------------------------------------------------------------ Abstract During the process of merging, close dual AGN, with two growing SMBHs hosted by a pair of merging galaxies, are predicted. Simulations further suggest that the highest levels of merger induced dual AGN activity occur on kpc scales where the high resolution of HST is required. While the theoretical model is clear, recent observational studies testing the merger driven AGN model have dramatically different scenarios and contradictory results. We have recently found a very high fraction of narrow line BAT detected QSOs (21%) showing hidden mergers (< 3 kpc) only visible in adaptive optics. We propose HST STIS spectroscopic observations of a sample of four very close mergers (0.2-1.9 kpc) to study dual AGN triggering in this final stage of galaxy mergers. Our goals are to 1) confirm the nuclei as dual AGN and 2) measure the kinematics and ionization with high resolution along the slit to understand the merger. These observations will form part of a well-characterized legacy study of all 57 X-ray selected nearby AGN from the sky Swift-BAT in close major mergers (<30 kpc, z<0.075). ------------------------------------------------------------------------------------ Observations Description ------------------------ Using adaptive optics we have identified a sample of very small separation mergers that are hidden to ground based imaging. We propose to use the high spatial resolution of HST along with STIS spectroscopy to measure emission lines in the two nuclei to 1) confirm the nuclei as dual AGN using emission line diagnostics or high ionization lines (e.g. Ne V) and 2) measure the kinematics and ionization with to understand the merger. We will use setups to cover the two emission line complexes (G430L for OIII/Hbeta and G750M for NII/Halpha). The orientation of the slit is chosen to cover the two nuclei. Our program requires specific slit orientations (ORIENT) which affects the scheduling. The slit is quite tightly constrained in order to capture the centroid of both galaxies +/-1 degrees. The tolerance is set by our desire for nuclear spectra of both galaxy nuclei. The angular separation of the two nuclei is between (at minimum 0.32'' for MCG-02-21-013 and at maximum 2.72'' for 2MASXJ0843). 14248( 2) - 22-Jul-2015 13:25:33 - [ 2] Most of the sources can be done in a single setup in 750M to cover all the emission lines, however, 2MAS0139 is at a somewhat higher redshift that requires two setups. We have chosen to do a 2 step dither and CR-split 2 for all observations because of the limit of 2 orbits. ------------------------------------------------------------------------------------ 14248( 2) -
