A new tidal scenario for double bar formation
Marcin Semczuk, Ewa L. Łokas, Adriana de Lorenzo-Cáceres +1
Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactions. We demonstrate the viability of…
Disc galaxies are still settling: The discovery of the smallest nuclear discs and their young stellar bars
Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +11
When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it to flow to the cent…
Composite Bulges -- III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
Aishwarya Ashok, Anil Seth, Peter Erwin +17
We present photometric and morphological analyses of nuclear star clusters (NSCs) -- very dense, massive star clusters present in the central regions of most galaxies -- in a sampl…
Deconstructing double-barred galaxies in 2D and 3D. I. Classical nature of the dominant bulges
A. de Lorenzo-Cáceres, J. Méndez-Abreu, B. Thorne +1
We present here a thorough photometric analysis of double-barred galaxies, consisting of i) two-dimensional photometric decompositions including a bulge, inner bar, outer bar, and…
Resolving the age bimodality of galaxy stellar populations on kpc scales
Stefano Zibetti, Anna R. Gallazzi, Y. Ascasibar +12
Galaxies in the local Universe are known to follow bimodal distributions in the global stellar populations properties. We analyze the distribution of the local average stellar-popu…
Orthogonal vertical velocity dispersion distributions produced by bars
Min Du, Juntai Shen, Victor P. Debattista +1
In barred galaxies, the contours of stellar velocity dispersions () are generally expected to be oval and aligned with the orientation of bars. However, many double-barred (S2B)…
