We develop and apply new techniques in order to uncover galaxy rotation curves (RC) systematics. Considering that an ideal dark matter (DM) profile should yield RCs that have no bias towards any particular radius, we find that the Burkert DM profile satisfies the test, while the Navarro-Frenk-While (NFW) profile has a tendency of better fitting the region between one and two disc scale lengths than the inner disc scale length region. Our sample indicates that this behaviour happens to more than… Expand

Novel constraints on fermionic dark matter from galactic observables II: Galaxy scaling relations
We have recently introduced a new model for the distribution of dark matter (DM) in galaxies, the Ruffini-Arg\"uelles-Rueda (RAR) model, based on a self-gravitating system of massive fermions atExpand
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 homogeneousExpand
Stellar-to-Halo Mass Ratio and Dark Matter Profiles
This paper seeks to verify if the inner halo density profile depends on the ratio between stellar and halo mass. The work follows the previous one by Del Popolo and Pace (2016), in which we studiedExpand
Galactic rotation curves versus ultralight dark matter: Implications of the soliton-host halo relation
Bosonic ultra-light dark matter (ULDM) would form cored density distributions at the center of galaxies. These cores, seen in numerical simulations, admit analytic description as the lowest energyExpand
Fifth force constraints from galaxy warps
Intragalaxy signals contain a wealth of information on fundamental physics, both the dark sector and the nature of gravity. While so far largely unexplored, such probes are set to rise dramaticallyExpand
Can light dark matter solve the core-cusp problem?
Recently, there has been much interest in light dark matter, especially ultralight axions, as they may provide a solution to the core-cusp problem at the center of galaxies. Since very light bosonsExpand
Absence of a fundamental acceleration scale in galaxies
Dark matter is currently one of the main mysteries of the Universe. There is much strong indirect evidence that supports its existence, but there is yet no sign of a direct detection1–3. Moreover, atExpand
Gravitational Lensing by a Massive Object in a Dark Matter Halo. I. Critical Curves and Caustics
We study the gravitational lensing properties of a massive object in a dark matter halo, concentrating on the critical curves and caustics of the combined lens. We model the system in the simplestExpand
Background Simulations and WIMP Search with Galactic Signature Dark Matter Experiments
There is now compelling evidence that ordinary baryonic matter only represents 15% of the matter content of the Universe. Observational results suggest that the remaining 85% may be constituted ofExpand
Fifth force constraints from the separation of galaxy mass components
One of the most common consequences of extensions to the standard models of particle physics or cosmology is the emergence of a fifth force. While generic fifth forces are tightly constrained atExpand


Modified gravity models and the central cusp of dark matter haloes in galaxies
The N-body dark matter (DM) simulations point that DM density profiles, e.g. the Navarro Frenk White (NFW) halo, should be cuspy in its centre, but observations disfavour this kind of DM profile.Expand
Surface density of dark matter haloes on galactic and cluster scales
In this paper, in the framework of the secondary infall model, the correlation between the central surface density and the halo core radius of galaxy, and cluster of galaxies, dark matter haloes wasExpand
The Structure of cold dark matter halos
High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile. RegardlessExpand
Low-mass disc galaxies and the issue of stability: MOND versus dark matter
We analyse the rotation curves and gravitational stability of a sample of six bulgeless galaxies for which detailed images reveal no evidence for strong bars. We explore two scenarios: Newtonian darkExpand
The distribution of dark matter around galactic or cluster halos has usually been assumed to be approximately isothermal with a non-zero core radius, which is expected to be of the order of the sizeExpand
Missing dark matter in dwarf galaxies
We use cosmological hydrodynamical simulations of the APOSTLE project to examine the fraction of baryons in CDM haloes that collect into galaxies. This ‘galaxy formation efficiency’ correlatesExpand
Accurate Determination of the Mass Distribution in Spiral Galaxies. II. Testing the Shape of Dark Halos
New high-resolution Fabry-Perot data at the Canada-France-Hawaii Telescope combined with published VLA 21 cm observations are used to determine the mass distribution of NGC 3109 and IC 2574. TheExpand
We derive rotation curves for four nearby, low-mass spiral galaxies and use them to constrain the shapes of their dark matter density profiles. This analysis is based on high-resolutionExpand
A constant dark matter halo surface density in galaxies
The recent finding that the central surface density � 0Dr0ρ0 of galaxy dark matter halos, where r0 and ρ0 are the halo core radius and central density, is nearly constant and independent of galaxy luminosity is confirmed. Expand
