Halo expansion in cosmological hydro simulations: toward a baryonic solution of the cusp/core problem in massive spirals

Gibson, Brad K.; Maccio, A. V.; Stinson, G.; Brook, C. B.; Wadsley, J.; Couchman, H. M. P.; Shen, S.; Quinn, T. (American Astronomical SocietyIOP Publishing, 2012-01-01)

A clear prediction of the cold dark matter (CDM) model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging ...
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 ...
MaGICC baryon cycle: the enrichment history of simulated disc galaxies

Brook, C. B.; Stinson, G.; Gibson, Brad K.; Shen, S.; Maccio, A. V.; Obreja, A.; Wadsley, J.; Quinn, T. (Oxford University Press, 2014-10-01)

Using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a Cosmological Context) project, spanning stellar mass from ∼10⁷ to 3 × 10¹⁰ M_☉, we trace the ...
MAGICC haloes: confronting simulations with observations of the circumgalactic medium at z = 0

Stinson, G. S.; Brook, C.; Prochaska, J. Xavier; Hennawi, Joe; Shen, Sijing; Wadsley, J.; Pontzen, Andrew; Couchman, H. M. P.; Quinn, T.; Maccio, Andrea V.; Gibson, Brad K. (Wiley-Blackwell, 2012-09)

We explore the circumgalactic medium (CGM) of two simulated star-forming galaxies with luminosities L ≈ 0.1 and 1 L^★ generated using the smooth particle hydrodynamic code GASOLINE. These simulations are ...
