Double X/Peanut Structures in Barred Galaxies -- Insights from an --body Simulation
Bogdan C. Ciambur, Francesca Fragkoudi, Sergey Khoperskov +2
Boxy, peanut- or X-shaped "bulges" are observed in a large fraction of barred galaxies viewed in, or close to, edge-on projection, as well as in the Milky Way. They are the product…
The disc origin of the Milky Way bulge: On the necessity of the thick disc
P. Di Matteo, F. Fragkoudi, S. Khoperskov +4
In the MW bulge, metal-rich stars form a strong bar and are more peanut-shaped than metal-poor stars. It has been recently claimed that this behavior is driven by the initial in-pl…
Quantifying the (X/peanut)-shaped Structure of the Milky Way - New Constraints on the Bar Geometry
Bogdan C. Ciambur, Alister W. Graham, Joss Bland-Hawthorn
The nature, size and orientation of the dominant structural components in the Milky Way's inner ~4 kpc - specifically the bulge and bar - have been the subject of conflicting inter…
Implications for the origin of dwarf early-type galaxies: a detailed look at the isolated rotating dwarf early-type galaxy CG 611, with ramifications for the Fundamental Plane's (S_K)^2 kinematic scaling and the spin-ellipticity diagram
Alister W. Graham, Joachim Janz, Samantha J. Penny +4
Selected from a sample of nine, isolated, dwarf early-type galaxies (ETGs) having the same range of kinematic properties as dwarf ETGs in clusters, we use CG 611 (LEDA 2108986) to…
Quantifying the (X/Peanut)-Shaped Structure in Edge-on Disc Galaxies: Length, Strength, and Nested Peanuts
Bogdan C. Ciambur, Alister W. Graham
X-shaped or peanut-shaped (X/P) bulges are observed in more than 40% of (nearly) edge-on disc galaxies, though to date a robust method to quantify them is lacking. Using Fourier ha…
