    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 origin of magnetic driven winds and the structure of the galactic dynamo in isolated galaxies
    We investigate the build-up of the galactic dynamo and subsequently the origin of a magnetic driven outflow. We use a set-up of an isolated disc galaxy with a...

    On the Origin of the Type II Spicules: Dynamic Three-dimensional MHD Simulations
    Recent high temporal and spatial resolution observations of the chromosphere have forced the definition of a new type of spicule, "type II's," that are...
  • Publication
    On the Rapidly Cooling Interior of Supergalactic Winds
    Here we present the steady-state numerical solution and two-dimensional hydrodynamic calculations of supergalactic winds, taking into consideration strong...
  • Publication
    On the Reliability of Microvariability Tests in Quasars
    Microvariations probe the physics and internal structure of quasars. Unpredictability and small flux variations make this phenomenon elusive and difficult to...

    On the use of field RR Lyrae as Galactic probes: VII. Light curve templates in the LSST photometric system
    Context. The Vera C. Rubin Observatory will start operations in 2025. During its first two years, too few visits per target per band will be available, meaning...

    On the Variation of the Peak Asymmetry of Low-l Solar p Modes
    The resonant peaks of solar p modes show small amounts of asymmetry in frequency. Here, we use five independent sets of contemporaneous data, collected over a ~...

    On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
    The performance of adaptive optics systems is partially dependent on the algorithms used within the real-time control system to compute wavefront slope...

    Optical and near-infrared observations of the GRB 970616 error box
    We report on near-infrared and optical observations of the GRB 970616 error box and of the X-ray sources discovered by ASCA and ROSAT in the region. No optical...
