    Nested and Single Bars in Seyfert and Non-Seyfert Galaxies
    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...

    Nested Bars with Different Pattern Speeds: NGC 2950
    We studied the SB0 galaxy NGC 2950, which hosts two nested stellar bars. We used the Tremaine-Weinberg method to measure the pattern speed of the primary bar...

    Neutral and ionized gas dynamics in Blue Compact Dwarf Galaxies
    We propose to carry out full-synthesis (12-h) HI ATCA observations of 6 bright Blue Compact Dwarf Galaxies (BCDGs). The HIPASS data of these objects indicate...
