Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

When interpreted within the standard framework of Newtonian gravity and dynamics, the
kinematics of stars and gas in dwarf galaxies reveals that most of these systems are …

Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that
the mass of the dark matter halo and the total stellar mass are coupled through a function …

We study the link between baryons and dark matter (DM) in 240 galaxies with spatially
resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all …

We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular
galaxies (dIrrs), and we show that dIrrs obey the same mass–metallicity relation as the dwarf …

The cold dark matter (CDM) cosmological model has been remarkably successful in
explaining cosmic structure over an enormous span of redshift, but it has faced persistent …

Well-motivated elementary particle candidates for the dark matter, such as the sterile
neutrino, behave as warm dark matter (WDM). For particle masses of the order of a keV, free …

We present an all-sky catalog of 869 nearby galaxies having individual distance estimates
within 11 Mpc or corrected radial velocities V LG< 600 km s− 1. The catalog is a renewed …

We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations
that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and …

Dwarf satellite galaxies are thought to be the remnants of the population of primordial
structures that coalesced to form giant galaxies like the Milky Way. It has previously been …
