The ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its
maturity. It is clearly able to describe the universe at large scale, even if some issues remain …

The Milky Way's dwarf spheroidal satellites include the nearest, smallest and least luminous
galaxies known. They also exhibit the largest discrepancies between dynamical and …

We introduce a mass-dependent density profile to describe the distribution of dark matter
within galaxies, which takes into account the stellar-to-halo mass dependence of the …

Aims. We constrain the mass, velocity-anisotropy, and pseudo-phase-space density profiles
of the z= 0.44 CLASH cluster MACS J1206. 2-0847, using the projected phase-space …

This paper is based on lectures given at the IX Mexican School on Gravitation and
Mathematical Physics. The lectures (as the paper) were a broad-band review of the current …

This review aims at proposing to the field an overview of the Cusp-core problem, including a
discussion of its advocated solutions, assessing how each can satisfactorily provide a …

The inner slope (γ DM) of the dark matter (DM) density profile of cosmological halos carries
information about the properties of DM and/or baryonic processes affecting the halo …

Abstract We apply the Jeans Anisotropic Multi-Gaussian Expansion dynamical modelling
method to SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey data of early …

In the present paper, we compare the predictions of two well known mechanisms considered
able to solve the cusp/core problem (a. supernova feedback; b. baryonic clumps-DM …

A century ago, in 1911 and 1913, Plummer and then Reynolds introduced their models to
describe the radial distribution of stars innebulae'. This article reviews the progress since …
