    Outer edges of face-on spiral galaxies. Deep optical imaging of NGC 5923, UGC 9837 and NGC 5434
    We present deep optical imaging of three face-on disk galaxies together with a detailed description of the reduction and calibration methods used, in order to...

    Outflows from Active Galactic Nuclei: Kinematics of the Narrow-line and Coronal-line Regions in Seyfert Galaxies
    As part of an extensive study of the physical properties of active galactic nuclei (AGNs) we report high spatial resolution near-IR integral-field spectroscopy...
  • Publication
    Outflows from starburst galaxies with various driving mechanisms and their X-ray properties
    Outflows in starburst galaxies driven by thermal-mechanical energy, cosmic rays, and their mix are investigated with 1D and 2D hydrodynamic simulations. We show...
  • Publication
    Outflows of Low and High Ionization Gas in Nearby AGN
    We present results from a survey of nearby AGN using the adaptive optics assisted integral-field spectrometer SINFONI on the VLT. These data enable us to study...

    Outflows of Very Ionized Gas in the Centers of Seyfert Galaxies: Kinematics and Physical Conditions
    Mid-resolution spectra are used to deduce the size and kinematics of the coronal region in a sample of Seyfert galaxies by means of observations of the [Fe XI]...

    Outside-In Disk Evolution in the Large Magellanic Cloud
    From the analysis of the color-magnitude diagrams and color functions of four wide LMC fields located from ~=2 to 6 kpc from the kinematic center of the LMC we...

    Outskirts of spiral galaxies: result of a secular evolution process?.
    We present our recent results on the properties of the outskirts of disk galaxies. In particular, we focus on spiral galaxies with stellar disk truncations in...
  • Publication
    Overdensity of galaxies in the environment of quasar pairs
    We report on a study of the galaxy environments of low redshift physical quasars pairs. We selected 20 pairs having projected separation 0.5 Mpc and difference...

    Overview of the SDSS-IV MaNGA Survey: Mapping nearby Galaxies at Apache Point Observatory
    We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core...
