X-ray, Ly-alpha and H-alpha Emission from Simulated Disk Galaxies
Jesper Sommer-Larsen, Sune Toft, Jesper Rasmussen +3
The X-ray properties of the haloes of disk galaxies formed in fully cosmological, hydro/gravity simulations are discussed. The results are found to be consistent with observational…
The Mass to Light ratio and the Initial Mass Function in galactic discs
L. Portinari, J. Sommer-Larsen, R. Tantalo
A low mass-to-light ratio for the baryonic component of spiral galaxies is advocated by a number of dynamical studies and by cosmological simulations of galaxy formation. We discus…
Galaxy Formation: Warm Dark Matter, Missing Satellites, and the Angular Momentum Problem
Martin Goetz, Jesper Sommer-Larsen
We present warm dark matter (WDM) as a possible solution to the missing satellites and angular momentum problem in galaxy formation and introduce improved initial conditions for nu…
CDM, Feedback and the Hubble Sequence
Jesper Sommer-Larsen, Martin Gotz, Laura Portinari
We have performed TreeSPH simulations of galaxy formation in a standard LCDM cosmology, including effects of star formation, energetic stellar feedback processes and a meta-galacti…
The Density Profile of Cluster-scale Dark Matter Halos
Haakon Dahle, Steen Hannestad, Jesper Sommer-Larsen
We measure the average gravitational shear profile of 6 massive clusters (M_vir ~ 10^15 M_sun) at z=0.3 out to a radius ~2h^-1 Mpc. The measurements are fitted to a generalized NFW…
Galaxy Formation: CDM, Feedback and the Hubble Sequence
Jesper Sommer-Larsen, Martin Gotz, Laura Portinari
TreeSPH simulations of galaxy formation in a LCDM cosmology, with star formation, energetic stellar feedback and a meta-galactic UV field have been performed, resulting in realisti…
