    On the Compact H II Galaxy UM 408 as Seen by GMOS-IFU: Physical Conditions
    We present Integral Field Unit GMOS-IFU data of the compact H II galaxy UM 408, obtained at the Gemini South telescope, in order to derive the spatial...

    On the Connection Between Shape and Stellar Population in Early-type Galaxies
    We report on the discovery of a relation between the stellar mass M* of early-type galaxies (hereafter ETGs), their shape, as parameterized by the Sersic index...

    On the Connection of the Apparent Proper Motion and the VLBI Structure of Compact Radio Sources
    Many of the compact extragalactic radio sources that are used as fiducial points to define the celestial reference frame are known to have proper motions...

    On the Curvature of Dust Lanes in Galactic Bars
    We test the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of...

    On the dearth of C-enhanced metal-poor stars in the galactic bulge
    The chemical fingerprints of the first stars are retained within the photospheres of ancient unevolved metal-poor stars. A significant fraction of these stellar...

    On the Dearth of Ultra-faint Extremely Metal-poor Galaxies
    Local extremely metal-poor galaxies (XMPs) are of particular astrophysical interest since they allow us to look into physical processes characteristic of the...

    On the Distance and Reddening of the Starburst Galaxy IC 10
    We present deep and accurate optical photometry of the Local Group starburst galaxy IC 10. The photometry is based on two sets of images collected with the...

    On the dust content of galaxy clusters
    Context. Most of the contribution to dust emission in clusters of galaxies comes from late-type galaxies. However, several ejection processes of material from...

    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...
