Warm dark matter at small scales: peculiar velocities and phase space density
Warm dark matter small scales peculiar velocities phase space density
2010/11/12
We study the scale and redshift dependence of the power spectra for density perturbations and
peculiar velocities, and the evolution of a coarse grained phase space density for (WDM) particles that d...
Averting the magnetic braking catastrophe on small scales: disk formation due to Ohmic dissipation
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
We perform axisymmetric resistive MHD calculations that demonstrate that centrifugal disks can indeed form around Class 0 objects despite magnetic braking. We follow the evolution of a prestellar core...
