NuSTAR view of the black hole wind in the galaxy merger IRAS F11119$+$3257

摘要: Galactic winds driven by active galactic nuclei (AGN) have been invoked to play a fundamental role in the co-evolution between supermassive black holes and their host galaxies. Finding observational evidence of such feedback mechanisms is crucial importance it requires multi-wavelength approach order compare at different scales phases. In Tombesi et al. (2015) we reported detection powerful ultra-fast outflow (UFO) Suzaku X-ray spectrum ultra-luminous infrared galaxy IRAS F11119$+$3257. The comparison with galaxy-scale OH molecular observed Herschel same source supported energy-conserving scenario for AGN feedback. main objective this work perform an independent check results using higher sensitivity wider continuum coverage NuSTAR. We clearly detect highly ionized Fe K UFO 100ks NuSTAR parameters $N_H = (3.2\pm1.5)\times 10^{24}$ cm$^{-2}$, log$\xi$$=$$4.0^{+1.2}_{-0.3}$ erg s$^{-1}$ cm, $v_{\text{out}} 0.253^{+0.061}_{-0.118}$ c. launching radius likely distance $r \ge 16$ $r_s$ from hole. mass rate range $\dot{M}_{out}$$\simeq$0.5-2 $M_{\odot}$ yr$^{-1}$. momentum power are $\dot{P}_{out} \simeq$0.5-2 $L_{AGN}/c$ $\dot{E}_{out} \simeq$7-27\% $L_{AGN}$, respectively. consistent 2013 2015 observations. Only column density found be variable, possibly suggesting clumpy wind. energetics outflows estimated millimeter wavelengths support connection nuclear luminous AGN.
