Description
We analyze the observed properties of nested and single stellar bar systems in disk galaxies. Our sample consists of 56 Seyfert and 56 non-Seyfert galaxies. We use HST H-band images of the central parts and ground-based images of the outer parts with ellipse fitting to find bars. Our main result is a clear division between the secondary and primary bars in terms of bar length. We show that single bars have different properties from nested bars. We also confirm a statistically significant prevalence of bars among the Seyfert galaxies when compared to non-Seyfert galaxies.

    Confronting Dark Matter Models with Nearby Dwarf Irregular Galaxies
    Dwarf irregular galaxies, due to their lower masses, relative isolation, and high-quality data availability, are ideal laboratories to test various models of dark matter. In particular, the existence, morphology and formation of central cores in dwarf galaxies has been a contentious issue in the literature in light of apparent tensions with the

    Quantifying the typical scale of star formation in the spiral arms through their young stellar clusters
    Star formation is a vital phenomenon across all fields of astronomy, shaping our universe in all its vastness, from the small scale of exoplanets to the large scales of galaxies and beyond. There are nevertheless still many unknowns surrounding star formation because of its complexity. Spiral arms are important sites of star formation, yet in spite

    A new era in galaxy edge characterisation with ultra-deep imaging
    For the first time, the LIGHTS survey is routinely imaging galaxies at a depth and spatial resolution comparable to what LSST will produce in 10 years (i.e. ~31 mag/arcsec^2). This opens up the possibility of probing the edge of galaxies with a precision that we have not been able to achieve in the past. While we have been limited to one
