    Bar Evolution over the Last 8 Billion Years: A Constant Fraction of Strong Bars in the GEMS Survey
    One-third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve...

    Bar pattern speed and position of the circumnuclear ring in NGC 1097
    We present the first galactic-scale model of the gas dynamics of the prototype barred Seyfert 1 galaxy NGC 1097. We use large-scale FaNTOmM Fabry-Perot...

    Bar pattern speed at z∼1-2 to explore challenges of the Standard Cosmology
    Stellar bars drive the galaxy secular evolution. While rotating around the galaxy centre with a given angular frequency, the bar pattern speed, they sweep...

    Bar pattern speed evolution over the last 7 Gyr
    Context. The tumbling pattern of a bar is the main parameter characterising its dynamics. From numerical simulations, its evolution since bar formation is...

    Bar pattern speeds in CALIFA galaxies. I. Fast bars across the Hubble sequence
    Context. The bar pattern speed (Ωb) is defined as the rotational frequency of the bar, and it determines the bar dynamics. Several methods have been proposed...

    Bar pattern speeds in CALIFA galaxies. II. The case of weakly barred galaxies
    Context. About 35% of the nearby disc galaxies host a weak bar for which different formation scenarios, including the weakening of a strong bar and tidal...

    Bar pattern speeds in CALIFA galaxies. III. Solving the puzzle of ultrafast bars
    Context. More than 10% of barred galaxies with a direct measurement of the bar pattern speed host an ultrafast bar. These bars extend well beyond the corotation...

    Bar properties as a function of wavelength: a local baseline with S<SUP>4</SUP>G for high-redshift studies
    The redshift evolution of bars is an important signpost of the dynamic maturity of disc galaxies. To characterize the intrinsic evolution safe from band...
