TL;DR: In this article, the spatial distribution of dwarf satellites in galactic dark matter halos using dissipationless cosmological simulations of the concordance flat cold dark matter (CDM) model with vacuum energy is studied.

TL;DR: In this article, the authors used the rotation curves of a sample of dark matter dominated dwarf and low surface brightness (LSB) late-type galaxies to study their radial mass distributions, and they found that the shape of the rotation curve is remarkably similar for all (both dwarf and LSB) galaxies in the sample, suggesting a self-similar density distribution of their dark matter (DM) halos.

TL;DR: In this article, the authors developed a much more realistic prescription for modeling the feedback of galaxy formation, which minimizes any ad hoc subgrid physics, and found that this can be achieved only by doing what the real universe does: formation of dense (>10 H atoms cm-3), cold (T ≈ 100 K) molecular phase, where the star formation happens, and which young stars disrup.

TL;DR: In this article, the authors used a modern compilation of observational data along with the best available large-scale cosmological simulation of dark matter (DM) and found that 1 fits all basic statistics of galaxies with circular velocities Vcirc > 80 km s − calculated at a radius of ∼10 kpc.

TL;DR: In this article, a new dynamical classification of the cosmic web is proposed, which is based on counting the number of eigenvalues above a certain threshold, λth, at each grid point, where the case of zero, one, two or three such eigen values corresponds to void, sheet, filament or a knot grid point.
