Observational Evidence for Spin Alignment between Galaxy Groups and Their Central Galaxies
The Astrophysical Journal LettersWe present a systematic observational study of the spin alignment between galaxy groups and their central galaxies using a large spectroscopic sample from the Sloan Digital Sky Survey.

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 ...

Form flows function: Learner‐centered game Re‐design in a STEM classroom
British Educational Research Journal, EarlyView.Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

The properties of fossil groups of galaxies [PDF]
Astronomische Nachrichten, 2009 AbstractNumerical simulations as well as optical and X‐ray observations over the last few years have shown that poor groups of galaxies can evolve to what is called a fossil group. Dynamical friction as the driving process leads to the coalescence of individual galaxies in ordinary poor groups leaving behind nothing more than a central, massive ...

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
, 2006 In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...
