    Integral field spectroscopy based Hα sizes of local luminous and ultraluminous infrared galaxies. A direct comparison with high-z massive star-forming galaxies
    Aims: We study the analogy between local luminous and ultraluminous infrared galaxies (U/LIRGs) and high-z massive star forming galaxies (SFGs) by comparing...

    Integral field spectroscopy of nearby quasi-stellar objects - II. Molecular gas content and conditions for star formation
    We present single-dish 12CO(1-0) and 12CO(2-1) observations for 14 low-redshift quasi-stellar objects (QSOs). In combination with optical integral field...

    Ionized gas kinematics of galaxies in the CALIFA survey. I. Velocity fields, kinematic parameters of the dominant component, and presence of kinematically distinct gaseous systems
    Context. Ionized gas kinematics provide important clues to the dynamical structure of galaxies and hold constraints to the processes driving their evolution...

    IR images of N159 in the LMC.
    The authors obtained near infrared images in J, H, and K filters of the H II region N159 in the LMC with the IR Imager on the 1.5 m telescope of CTIO. Some 50...

    IRAS 06562-0337 - Final mass-loss episodes before the formation of a planetary nebula?
    The onset of forbidden line emission in the spectrum of a proto-planetary nebula has been detected for the first time in the lapse of only two years. IRAS 06562...

    Is star formation a stochastic or a regulated process?
    The stellar initial mass function (IMF) is usually assumed to be a probability density distribution function. Recent data appear to question this interpretation...

    Isolated galaxies in the Local Group .
    Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their...
