Isolated and Interacting Galaxies : Simulations with GRAPE
I present N-body simulations of isolated and interacting galaxies, made on GRAPE machines. In particular I discuss the formation and evolution of N-body bars and compare their properties to those of bars in early-type and late-type galactic discs. I argue that the halo can help the bar grow, contrary to previous beliefs, by taking positive angular momentum from it via its resonant stars. I then...
متن کاملLaguerre approximation of stable manifolds with application to connecting orbits
We present an algorithm, based on approximation by Laguerre polynomials, for computing a point on the stable manifold of a stationary solution of an autonomous system. A superconvergence phenomenon means that the accuracy of our results is much higher than the usual spectral accuracy. Both the theory and the implementation of the method are considered. Finally, as an application of the algorith...
متن کاملEngaging, interacting and connecting with our learners and teachers
In the first editorial of this year’s issue of Perspectives on Medical Education, Jan Borleffs [1] wrote about medical education being and becoming future proof: ‘Definitely, educational concepts based on previous approaches with proven effectiveness should be preserved, but the content of the programme needs to change in concurrence with the changes in society and the requirements for good hea...
متن کاملOf Interacting and Merging Galaxies
Gravitational interactions and mergers affect the morphologies and dynamics of galaxies from our Local Group to the limits of the observable universe. Observations of interacting galaxies at low redshifts (z ∼< 0.2) yield detailed information about many of the processes at work. I briefly review these processes and the growing evidence that mergers play a major role in the delayed formation of ...
متن کاملInteracting galaxies and cosmological parameters
We propose a (physical)-geometrical method to measure Ωm◦ and ΩΛ◦, the present rates of the density cosmological parameters for a Friedmann-Lemâıtre universe. The distribution of linear separations between two interacting galaxies, when both of them undergo a first massive starburst, is used as a standard of length. Statistical properties of the linear separations of such pairs of “interactivat...
