Constraining the formation of inner bars. Photometry, kinematics and stellar populations in NGC 357
A. de Lorenzo-Cáceres, A. Vazdekis, J. A. L. Aguerri +2
Double-barred galaxies are common in the local Universe, with approximately one third of barred spirals hosting an smaller, inner bar. Nested bars have been proposed as a mechanism…
Radial Migration in Disk Galaxies I: Transient Spiral Structure and Dynamics
R. Roškar, V. P. Debattista, T. R. Quinn +1
We seek to understand the origin of radial migration in spiral galaxies by analyzing in detail the structure and evolution of an idealized, isolated galactic disk. To understand th…
Probing the shape and history of the Milky Way halo with orbital spectral analysis
Monica Valluri, Victor P. Debattista, Thomas R. Quinn +2
The phase space coordinates of individual halo stars obtained by Galactic surveys enable the computation of their full 3-dimensional orbits. Spectral analysis of halo orbits can be…
Constraining the role of star cluster mergers in nuclear cluster formation: Simulations confront integral-field data
Markus Hartmann, Victor P. Debattista, Anil Seth +2
We present observations and dynamical models of the stellar nuclear clusters (NCs) at the centres of NGC 4244 and M33. We then compare these to an extensive set of simulations test…
Implications of Radial Migration for Stellar Population Studies
R. Roškar, V. P. Debattista, S. R. Loebman +2
Recent theoretical work suggests that it may be common for stars in the disks of spiral galaxies to migrate radially across significant distances in the disk. Such migrations are a…
