The Nature of Dwarf Elliptical Galaxies: An Observing Project for OSIRIS
Although dwarf elliptical galaxies are the dominant galaxy population in nearby clusters, their origin and nature remain a mystery. The main aim of this project...
The Nature of Galactic Bulges from SAURON Absorption Line Strength Maps
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H$eta$, Mg b and Fe 5015 we derive SSP...
The Nature of Kink MHD Waves in Magnetic Flux Tubes
We examine the nature of MHD kink waves. This is done by determining the frequency, the damping rate and the eigenfunctions of MHD kink waves for three widely...
The Nature of Low-Ionization Microstructures in Planetary Nebulae
We present a gallery with some of the most interesting microstructures of low-ionization found in planetary nebulae (PNe). A rich zoo of knots, filaments, jets...
