Draft version July 30, 2007 A Preprint typ eset using L TEX style emulateap j v. 12/01/06 DARK-ENERGY DYNAMICS REQUIRED TO SOLVE THE COSMIC COINCIDENCE Chas A. Egan 1 ,2 & Charles H. Lineweaver 2 Draft version July 30, 2007 ABSTRACT Many exotic dark energy models are designed to solve the cosmic coincidence (why, just now is de m ?) by guaranteeing de m for significant fractions of the age of the universe. ... The first of these problems is concerned with the smallness of the dark energy density. ...

... The agreement between the simulated and observed gas kinematics permitted us to conclude that the galaxies with the highest rotation velocities tend to possess very massive stellar disks that dominate the gasdynamics within the optical radius. In less massive galaxies, with a maximal rotation velocity of less than 200 km sР1, the mass of the dark halo at least equals the stellar mass within 2-3 disk scale lengths. ... The most massive galaxies tend to possess disks with high mass fractions, fd . ...

... The resulting morphology and kinematics with different assumed pattern speeds, disc vertical thicknesses and dark halo contributions are compared with observations. Our models reproduce the main morphological features of this galaxy: the four-armed spiral, and the inner and nuclear rings. ... Thus, fast rotating bars could imply that the halo contribution is negligible in the inner parts of the disc. ... Quite often, the spiral arms emerge from an inner ring that surrounds the bar. ...

... But a small fraction of the light falls down the slit. This light is then dispersed by a prism or grating, and lands on the detector. ... Fibre Spectrographs. ... Most low/moderate dispersion spectrographs (such as the double beam spectrograph on the 2.3m) use blaized gratings such as these, and are typically run in first order. ... Working together, they cause dispersion, but the prism and grating bend light in opposite ways, so that at the central wavelength the light passes straight through. ...
