From galaxy formation theory we expect galaxies to be embedded in massive dark matter haloes. For spiral and dwarf galaxies this has indeed been observationally...
The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology...
Dark Matter in Spiral Galaxies: dynamical constraints
Dark Matter in Galaxies is an important subject of current astrophysical research. I will concentrate on spiral galaxies, and first give an overview of the...
Density distribution of the cosmological matter field
The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...
Detailed Theoretical Predictions for the Outskirts of Dark Matter Halos
In the present work we describe the formalism necessary to derive the properties of dark matter halos beyond 2 virial radii using the spherical collapse model...
Detection of satellite remnants in the Galactic halo with Gaia- III. Detection limits for ultrafaint dwarf galaxies
We present a method to identify ultrafaint dwarf galaxies (UFDGs) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its...
