    Observational evidence for triaxiality, and for relatively recent star formation in the bulge of NGC 4736
    CCD maps are presented of the inner 1.4 kpc of NGC 4736 in the B, V, R, I and Z bands, along with an ellipticity analysis of these, in which the ellipticities...

    Observational evidence for triggering in spirals.
    The authors discuss recent evidence that the massive star formation in the grand-design spiral galaxy M51 is triggered. Studying the symmetry of the Hα...

    Observations of [OI]63-=μm line emission in main-sequence galaxies at z ∼ 1.5
    We present Herschel-PACS spectroscopy of four main-sequence star-forming galaxies at z ∼ 1.5. We detect [OI]63-=μm line emission in BzK-21000 at z = 1.5213, and...

    OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2 - I. Survey description, data analysis, and star formation and AGN activity in the highest density regions
    We present an overview of and first results from the OMEGA (OSIRIS Mapping of Emission-line Galaxies in the multicluster system A901/2) survey. The ultimate...

    On the accretion of a new group of galaxies on to Virgo - II. The effect of pre-processing on the stellar population content of dEs
    Using MUSE spectra, we investigate how pre-processing and accretion on to a galaxy cluster affect the integrated stellar population properties of dwarf early...

    On the dust properties of the UV galaxies in the redshift range z 0.6-1.2
    Far-infrared observations from the Herschel Space Observatory are used to estimate the infrared (IR) properties of ultraviolet-selected galaxies. We stack the...

    On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback
    According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before z = 2...

    On the evolutionary status of two very active visual binaries
    HD 36705 (AB Doradus) and HD 155555 (V824 Ara) are two nearby very active cool stars. Both have strong Li I (lambda)6708 resonance lines, implying high surface...

    On the massive star-forming capacity of molecular clouds
    Assuming that photoionization is the self-limiting process for continued star formation, we estimate the maximum number of massive (OB) stars that can form...
