Over recent decades, cosmological simulations of galaxy formation have been instrumental
in advancing our understanding of structure and galaxy formation in the Universe. These …

Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

ABSTRACT We determine the Milky Way (MW) mass profile inferred from fitting physically
motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various …

This review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …

We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

Cosmological models in which dark matter consists of cold elementary particles predict that
the dark halo population should extend to masses many orders of magnitude below those at …

The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

Predicting structural properties of dark matter haloes is one of the fundamental goals of
modern cosmology. We use the suite of MultiDark cosmological simulations to study the …

We present new H i interferometric observations of the gas-rich ultra-diffuse galaxy AGC
114905, which previous work, based on low-resolution data, identified as an outlier of the …

The relation between halo mass, M, and concentration, c, is a critical component in our
understanding of the structure of dark matter halos. While numerous models for this relation …
