    CEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3-9 with JWST
    We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3-9 using early James...

    Colors and color gradients in bulges of galaxies
    We have obtained surface photometry in U, B, R, and I for a complete optically selected sample of 45 early-type spiral galaxies, to investigate the colors and...

    Composite Bulges. III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
    We present photometric and morphological analyses of nuclear star clusters (NSCs)-very dense, massive star clusters present in the central regions of most...

    Deep HST Imaging Favors the Bulgeless Edge-on Galaxy Explanation for the Hypothetical Stellar Wake Created by a Runaway Supermassive Black Hole
    A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a...

    Dynamical simulations of the interacting galaxies in the NGC 520/UGC 957 system
    Numerical simulations of the interacting galaxies in the NGC 520/UGC 957 system are presented. Two sets of models were produced to investigate the postulated...

    Extragalactic Magnetism with SOFIA (SALSA Legacy Program). V. First Results on the Magnetic Field Orientation of Galaxies
    We present the analysis of the magnetic field (B-field) structure of galaxies measured with far-infrared (FIR) and radio (3 and 6 cm) polarimetric observations...

    Flares, Warps, Truncations, and Satellite: The Ultra-thin Galaxy UGC 11859
    The structure of the outskirts of galaxies provides valuable information about their past and evolution. Due to their projected orientation, edge-on isolated...

    From Naked Spheroids to Disky Galaxies: How Do Massive Disk Galaxies Shape Their Morphology?
    We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we...

    Further evidence of continuity between elliptical and disc galaxies
    The behavior of the isophotes of the E galaxies in a new photometric sample of 33 early-type galaxies belonging to the Virgo cluster (Caon) is compared to that...
