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…
The Profiles of Bars in Spiral Galaxies
Peter Erwin, Victor P. Debattista, Stuart Robert Anderson
We present an analysis of major-axis surface-brightness profiles of bars in a volume-limited sample of 182 barred spiral galaxies, using Spitzer 3.6 micron images. Unlike most prev…
Composite Bulges -- IV. Detecting Signatures of Gas Inflows in the IFU data: The MUSE View of Ionized Gas Kinematics in NGC 1097
Tutku Kolcu, Witold Maciejewski, Dimitri A. Gadotti +8
Using VLT/MUSE integral-field spectroscopic data for the barred spiral galaxy NGC 1097, we explore techniques that can be used to search for extended coherent shocks that can drive…
Orbital support and evolution of flat profiles of bars (shoulders)
Leandro Beraldo e Silva, Victor P. Debattista, Stuart R. Anderson +4
Many barred galaxies exhibit upturns (shoulders) in their bar major-axis density profile. Simulation studies have suggested that shoulders are supported by looped orbits, occ…
The interplay between accretion, galaxy downsizing and the formation of box/peanut bulges in TNG50
Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista +6
From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass at . We search for box/peanut bulges (BPs…
Testing for relics of past strong buckling events in edge-on galaxies: Simulation predictions and data from SG
V. Cuomo, V. P. Debattista, S. Racz +7
The short-lived buckling instability is responsible for the formation of at least some box/peanut (B/P) shaped bulges, which are observed in most massive, , barred galaxies. N…
