Powerful, galactic outflows driven by Active Galactic Nuclei (AGNs) are commonly considered as a main mechanism to regulate star formation in massive galaxies. Ultra- and hyper-luminous IR galaxies (U/HyLIRGs) are thought to represent a transition phase of galaxies from a rapidly growing period to a quiescent status as gas swept out by outflows, providing a laboratory to investigate outflows and their feedback effects on the hosts. In this paper we report recent Gemini and ALMA observations of a HyLIRG, J1126 at z=0.46842, which has been identified with a puzzling co-existence of a fast ionized outflow (>2000 km s⁻¹) and an intense starburst (star formation rate of 800 M_⊙ yr⁻¹). The Gemini observation shows the fast ionized outflow is extended to several kpc with a mass-loss rate of 180 M_⊙ yr⁻¹. A massive molecular outflow with a high mass-loss rate (2500 M_⊙ yr⁻¹) is revealed by ALMA. The multi-phase outflows show large factors of momentum boost and loading of kinetic power, indicating a driving by thermal pressure of a nuclear hot wind and/or radiation pressure of a highly obscured AGN. In addition to ejection of kinetic energy, it is also found that the powerful outflow can induce an ionizing shock in the galaxy disk and enhance the excitation and dissociation of molecular gas. The powerful outflow probably results in an instantaneous negative feedback and shows potential to regulate the host growth in a long term.
