Potential Black Hole Seeding of the Spiral Galaxy NGC 4424 via an Infalling Star Cluster
Alister W. Graham, Roberto Soria, Bogdan C. Ciambur +2
Galaxies can grow through their mutual gravitational attraction and subsequent union. While orbiting a regular high-surface-brightness galaxy, the body of a low-mass galaxy can be…
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…
Searching for Intermediate Mass Black Holes in galaxies with Low Luminosity AGN: A multiple-method approach
Filippos Koliopanos, Bogdan C. Ciambur, Alister W. Graham +7
Aims: This work is the first stage of a campaign to search for IMBHs, in low luminosity AGN (LLAGN) and dwarf galaxies. An additional, and equally important, aim of this pilot stud…
Disky elliptical galaxies and the allegedly over-massive black hole in the compact massive `ES' galaxy NGC 1271
Alister W. Graham, Bogdan C. Ciambur, Giulia A. D. Savorgnan
While spiral and lenticular galaxies have large-scale disks extending beyond their bulges, and most local early-type galaxies with 10^{10} < M_*/M_Sun < 2x10^{11} contain a disk (e…
- A Fast and Versatile New Program for Decomposing Galaxy Light Profiles
Bogdan C. Ciambur
I introduce , a new, user-friendly program written in and designed to analyse the radial surface brightness profiles of galaxies. With an intuitive graphical use…
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…
Does the intermediate mass black hole in LEDA 87300 (RGG 118) follow the near-quadratic (M_bh)-(M_spheroid) relation?
Alister W. Graham, Bogdan C. Ciambur, Roberto Soria
The mass scaling relation between supermassive black holes and their host spheroids has previously been described by a quadratic or steeper relation at low masses (10^5 < M_bh/M_su…
Beyond Ellipse(s): Accurately Modelling the Isophotal Structure of Galaxies with and
Bogdan C. Ciambur
This work introduces a new fitting formalism for isophotes which enables more accurate modelling of galaxies with non-elliptical shapes, such as disk galaxies viewed edge-on or gal…
On the Evolution of the Bi-Modal Distribution of Galaxies in the Plane of Specific Star Formation Rate versus Stellar Mass
Bogdan C. Ciambur, Guinevere Kauffmann, Stijn Wuyts
We have compared the observed distribution of galaxies in the plane of specific star formation rate versus stellar mass with the predictions of the Garching semi-analytic model at…
