Hierarchical formation of bulgeless galaxies – II. Redistribution of angular momentum via galactic fountains

Gibson, Brad K.; Brook, C. B.; Stinson, G.; Roskar, R.; Wadsley, J.; Quinn, T. (Oxford University Press, 2012-01)

Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 km s[superscript −1], and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We ...
The VVV Survey reveals classical Cepheids tracing a young and thin stellar disk across the Galaxy's bulge
