    A Morphological and Statistical Analysis of Ansae in Barred Galaxies
    Many barred galaxies show a set of symmetric enhancements at the ends of the stellar bar, called ansae, or the "handles" of the bar. Ansa bars have been in the...

    A morphological study of galaxies in ZwCl0024+1652, a galaxy cluster at redshift z ˜ 0.4
    The well-known cluster of galaxies ZwCl0024+1652 at z ˜ 0.4 lacks an in-depth morphological classification of its central region. While previous studies provide...

    A Morphological Type Dependence in the μ0-log h Plane of Spiral Galaxy Disks
    We present observational evidence for a galaxy ``type'' dependence to the location of a spiral galaxy's disk parameters in the μ0-logh plane. With a sample of...

    A multi-wavelength analysis of M 81: insight on the nature of Arp's loop
    Context. The optical ring-like structure detected by Arp (1965) around M 81 (commonly referenced as “Arp's loop”) represents one of the most spectacular...

    A Multiwavelength Study of Narrow-Line Seyfert 1 Galaxies from the Second Byurakan Survey
    In this work we present a multiwavelength study of narrow-line Seyfert 1 galaxies (NLS1s) discovered in the Second Byurakan Survey (SBS). The sample consists of...

    A Multiwavelength Study of NLS1 Galaxies from the Second Byurakan Survey
    In this work we present some results of the multiwavelength study performed to a sample of 26 NLS1s discovered in the Second Byurakan Survey (SBS NLS1s). One of...

    A multiwavelength view of the galaxy cluster Abell 523 and its peculiar diffuse radio source
    We study the structure of the galaxy cluster Abell 523 (A523) at z = 0.104 using new spectroscopic data for 132 galaxies acquired at the Telescopio Nazionale...

    A MUSE study of the fast bar in the weakly-interacting galaxy NGC 4264
    We present surface photometry and stellar kinematics of NGC 4264, a lenticular galaxy in the region of the Virgo Cluster undergoing a tidal interaction with its...

    A Near-infrared Census of the Multicomponent Stellar Structure of Early-type Dwarf Galaxies in the Virgo Cluster
    The fraction of star-forming to quiescent dwarf galaxies varies from almost infinity in the field to zero in the centers of rich galaxy clusters. What is...
