Determination of resonance locations in NGC 613 from morphological arguments
Marc Seigar, Amber Harrington, Patrick Treuthardt
In this paper, we present BVRI imaging data of NGC 613. We use these data to determine the corotation radius of the bar, using the photometric phase crossing method. This method us…
The Illustris Simulation: Supermassive Black Hole - Galaxy Connection Beyond the Bulge
Burçin Mutlu-Pakdil, Marc S. Seigar, Ian B. Hewitt +3
We study the spiral arm morphology of a sample of the local spiral galaxies in the Illustris simulation and explore the supermassive black hole - galaxy connection beyond the bulge…
A photometric study of the peculiar and potentially double ringed, non-barred galaxy: PGC 1000714
Burcin Mutlu Pakdil, Mithila Mangedarage, Marc S. Seigar +1
We present a photometric study of PGC 1000714, a galaxy resembling Hoag's Object with a complete detached outer ring, that has not yet been described in the literature. Since the H…
Determination of resonance locations in barred spiral galaxies using multiband photometry
Amber D. Sierra, Marc S. Seigar, Patrick Treuthardt +1
In this paper, we apply a method identified by Puerari & Dottori (1997) to find the corotation radii (CR) in spiral galaxies. We apply our method to 57 galaxies, 17 of which have a…
On the Link Between Central Black Holes, Bar Dynamics, and Dark Matter Halos in Spiral Galaxies
Patrick Treuthardt, Marc S. Seigar, Amber D. Sierra +5
The discovery of a relationship between supermassive black hole (SMBH) mass and spiral arm pitch angle (P) is evidence that SMBHs are tied to the overall secular evolution of a gal…
Dynamical Simulations of NGC 2523 and NGC 4245
P. Treuthardt, H. Salo, R. Buta
We present dynamical simulations of NGC 2523 and NGC 4245, two barred galaxies (types SB(r)b and SB(r)0/a, respectively) with prominent inner rings. Our goal is to estimate the bar…
