Soft Cores in Late-Type Dwarf and LSB Galaxies from HαObservations
D. Marchesini, E. D'Onghia, G. Chincarini +4
We present high spatial resolution Hαrotation curves of late-type dwarf and LSB galaxies. From our analysis we find good agreement between our Hαdata and the HI observations taken…

Dark Matter in the center of galaxies and galaxy clusters: ruling out the CDM scenario?
E. D'Onghia, G. Chincarini, C. Firmani +1
This work is focused on the preliminary results of the observations of Hαrotation curves for some of the late type dwarf and LSB galaxies carried out at the TNG telescope. In light…

Shallow cores in the dark matter halos: self-interaction in action?
V. Avila-Reese, C. Firmani, E. D'Onghia +1
Using observational data for a sample of dark matter dominated galaxies and two cluster of galaxies, we have found that the central halo density does not depend on its mass, and th…
