    On the missing second generation AGB stars in NGC 6752
    In recent years the view of Galactic globular clusters as simple stellar populations has changed dramatically, it is now thought that basically all globular...

    On the morphology of dust lanes in galactic bars
    The aim of our study is to use dynamical simulations to explore the influence of two important dynamical bar parameters, bar strength and bar pattern speed on...

    On the morphology of sigma-drop galaxies
    Context: Local reductions of the stellar velocity dispersion in the central regions of galaxies are known as sigma-drops (σ-drops). Knowing the origin of these...

    On the multiplicity of ALMA Compact Array counterparts of far-infrared bright quasars
    We present ALMA Atacama Compact Array (ACA) 870 μm continuum maps of 28 infrared-bright SDSS quasars with Herschel/SPIRE detections at redshifts 2-4, the...

    On the nature of Hα emitters at z ˜ 2 from the HiZELS survey: physical properties, Lyα escape fraction and main sequence
    We present a detailed multiwavelength study (from rest-frame ultraviolet to far-infrared) of narrow-band selected, star-forming (SF) Hα emitters (HAEs) at z ˜ 2...

    On the nature of the extragalactic number counts in the K-band
    Context: The galaxy number counts has been traditionally used to test models of galaxy evolution. However, the origin of significant differences in the shape of...

    On the nature of the red, 2MASS-selected AGN in the local Universe I: an optical spectroscopic study
    We present optical spectra for a representative sample of 27 nearby (z 0.2) Two Micron All Sky Survey (2MASS)-selected active galactic nuclei (AGN) with red...

    On the observational diagnostics to separate classical and disk-like bulges
    Flattened bulges with disk-like properties are considered to be the end product of secular evolution processes at work in the inner regions of galaxies. On the...

    On the Ongoing Multiple Blowout in NGC 604
    Several facts regarding the structure of NGC 604 are examined here. The three main cavities produced by the mechanical energy from massive stars, which in NGC...
