Dynamics of the disks of nearby galaxies [PDF]
Astronomische Nachrichten, 2008 AbstractI describe how the dynamics of galactic disks can be inferred by imaging and spectroscopy. Next I demonstrate that the decomposition of the rotation curves of spiral galaxies into the contributions by the various components of the galaxies is highly degenerate.

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies
Astronomische Nachrichten, EarlyView.ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

, 2007 We present our new scheme for the classification of radial stellar surface brightness profiles for disk galaxies. We summarize the current theoretical attempts to understand their origin and give an example of an application by comparing local galaxies with their counterparts at high redshift (z~1).

INTERLOCKING RESONANCE PATTERNS IN GALAXY DISKS [PDF]
The Astrophysical Journal Supplement Series, 2013 We have developed a method for finding dynamical resonances in disk galaxies using the change in sense of the radial component of the in-plane velocity at a resonance radius. Using simulations we show that we would expect to find these changes at corotation radii, with a weaker effect at the ILR and a small effect at the OLR. The method works well with

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping
Computer Graphics Forum, EarlyView.Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Disney's Auteur Problem: Framing Corporate Creativity in a Galaxy Far, Far Away
The Journal of Popular Culture, EarlyView.ABSTRACT At its core, Star Wars is a franchise George Lucas has led via his auteur vision. Since Lucas handed over the franchise reins to Disney, the company has courted several other auteurs to direct new entries in the series—each of those endeavors ended problematically.

New Phytologist, EarlyView.A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...
