We use a compilation of disc galaxy rotation curves to assess the role of the luminous component (‘baryons’) in the rotation curve diversity problem. As in earlier work, we find that rotation curve shape correlates with baryonic surface density: high surface density galaxies have rapidly rising rotation curves consistent with cuspy cold dark matter haloes; slowly rising rotation curves (characteristic of galaxies with inner mass deficits or ‘cores’) occur only in low surface density galaxies… 
From dwarf galaxies to galaxy clusters: Self-Interacting Dark Matter over 7 orders of magnitude in halo mass
In this paper we study the density profiles of self-interacting dark matter (SIDM) haloes spanning the full observable mass range, from dwarf galaxies to galaxy clusters. Using realistic simulations
Baryonic solutions and challenges for cosmological models of dwarf galaxies
Galaxies and their dark-matter halos have posed several challenges to the Dark Energy plus Cold Dark Matter (ΛCDM) cosmological model. These discrepancies between observations and theory intensify
A critical assessment of solutions to the galaxy diversity problem
Galactic rotation curves exhibit a diverse range of inner slopes. Observational data indicates that explaining this diversity may require a mechanism that correlates a galaxy's surface brightness
Active galactic nucleus and dwarf galaxy gas kinematics
We present spatially resolved kinematic measurements of stellar and ionized gas components of dwarf galaxies in the stellar mass range $10^{8.5} - 10^{10} M_{\odot}$, selected from SDSS DR7 and DR8
Dark Matters on the Scale of Galaxies
The cold dark matter model successfully explains both the emergence and evolution of cosmic structures on large scales and, when we include a cosmological constant, the properties of the homogeneous
Dark Matter Deficient Galaxies Produced via High-velocity Galaxy Collisions in High-resolution Numerical Simulations
The recent discovery of diffuse dwarf galaxies that are deficient in dark matter appears to challenge the current paradigm of structure formation in our universe. We describe numerical experiments to
On the radial acceleration of disc galaxies
The physical processes defining the dynamics of disc galaxies are still poorly understood. Hundreds of articles have appeared in the literature over the last decades without arriving at an
Observational constraints on the slope of the radial acceleration relation at low accelerations
The radial acceleration relation (RAR) locally relates the `observed' acceleration inferred from the dynamics of a system to the acceleration implied by its baryonic matter distribution. The relation
The Dekel-Zhao profile: a mass-dependent dark-matter density profile with flexible inner slope and analytic potential, velocity dispersion, and lensing properties
We explore a function with two shape parameters for the dark-matter halo density profile subject to baryonic effects, which is a special case of the general Zhao family of models applied to
To β or not to β: can higher order Jeans analysis break the mass–anisotropy degeneracy in simulated dwarfs?
We test a non-parametric higher-order Jeans analysis method, GravSphere, on 32 simulated dwarf galaxies comparable to classical Local Group dwarfs like Fornax. The galaxies are selected from the


The low-mass end of the baryonic Tully-Fisher relation
The scaling of disc galaxy rotation velocity with baryonic mass (the ‘baryonic Tully–Fisher’ relation, BTF) has long confounded galaxy formation models. It is steeper than the M ∝ V3 scaling relating
The unexpected diversity of dwarf galaxy rotation curves
We examine the circular velocity profiles of galaxies in A cold dark matter (CDM) cosmological hydrodynamical simulations from the EAGLE and LOCAL GROUPS projects and compare them with a compilation
The Link between the Baryonic Mass Distribution and the Rotation Curve Shape
The observed rotation curves of disc galaxies, ranging from late-type dwarf galaxies to early-type spirals, can be fit remarkably well simply by scal ing up the contributions of the stellar and H I
Self-Interacting Dark Matter Can Explain Diverse Galactic Rotation Curves.
The results demonstrate that the impact of the baryons on the SIDM halo profile and the scatter from the assembly history of halos as encoded in the concentration-mass relation can explain the diverse rotation curves of spiral galaxies.
MaGICC discs: matching observed galaxy relationships over a wide stellar mass range
We use the same physical model to simulate four galaxies that match the relation between stellar and total mass, over a mass range that includes the vast majority of disc galaxies. The resultant
Dark matter–baryon scaling relations from Einasto halo fits to SPARC galaxy rotation curves
Dark matter–baryon scaling relations in galaxies are important in order to constrain galaxy formation models. Here, we provide a modern quantitative assessment of these relations by modelling the
Bars in dark-matter-dominated dwarf galaxy discs.
We study the shape and kinematics of simulated dwarf galaxy discs in the APOSTLE suite of Lambda cold dark matter (Lambda CDM) cosmological hydrodynamical simulations. We find that a large fraction
Mass-Discrepancy Acceleration Relation: A Natural Outcome of Galaxy Formation in Cold Dark Matter Halos.
Analysis of the total and baryonic acceleration profiles of a set of well-resolved galaxies identified in the eagle suite of hydrodynamic simulations finds that galaxies exhibit a characteristic acceleration g_{†}, above which baryons dominate the mass budget, as observed.
The removal of cusps from galaxy centres by stellar feedback in the early Universe
Numerical simulations show that random bulk motions of gas in small primordial galaxies will result in a flattening of the central dark matter cusp on relatively short timescales (∼108 years), which would have operated in all star-forming galaxies at redshifts z ≥ 10.
We present new constraints on the density profiles of dark matter (DM) halos in seven nearby dwarf galaxies from measurements of their integrated stellar light and gas kinematics. The gas kinematics
