We present the Hi data for 5 spiral galaxies that, along with their Hα rotation curves, are used to derive the distribution of dark matter within these objects. A new method for extracting rotation curves from Hi data cubes is presented; this takes into account the existence of a warp and minimises projection effects. The rotation curves obtained are tested by taking them as input to construct model data cubes that are compared to the observed ones: the agreement is excellent. On the contrary… Expand
NGC 3741: the dark halo profile from the most extended rotation curve
We present new H i observations of the nearby dwarf galaxy NGC 3741. This galaxy has an extremely extended H i disc, which allows us to trace the rotation curve out to unprecedented distances inExpand
Radial dependence of the dark matter distribution in M33
The stellar and gaseous mass distributions, as well as the extended rotation curve in the nearby galaxy M33 are used to derive the radial distribution of dark matter density in the halo and to testExpand
A wide-field H I mosaic of Messier 31 - II. The disk warp, rotation, and the dark matter halo
Aims. We test cosmological models of structure formation using the rotation curve of the nearest spiral galaxy, M 31, determined using a recent deep, full-disk 21-cm imaging survey smoothed to 466 pcExpand
The distribution of dark and luminous matter inferred from extended rotation curves
A better understanding of the formation of mass structures in the Universe can be obtained by determining the amount and distribution of dark and luminous matter in spiral galaxies. To investigateExpand
The density profiles of Dark Matter halos in Spiral Galaxies
In spiral galaxies, we explain their nonKeplerian rotation curves (RCs) by means of a non-luminous component embedding their stellar-gaseous disks. Understanding the detailed properties of thisExpand

Density profiles of dark matter haloes on galactic and cluster scales
Aims. In the present paper, we improve the “extended secondary infall model” (ESIM) of Williams and collaborators to obtain further insights into the cusp/core problem. Methods. A secondary infallExpand
Cores of dark matter haloes correlate with stellar scalelengths
We investigate in detail the mass distribution obtained by means of high-resolution rotation curves of 25 galaxies of different morphological types. The dark matter contribution to the circularExpand
Disk galaxy rotation curves and dark matter distribution
The methods used to determine the rotation curves of the authors' Galaxy and other spiral galaxies in their outer parts, and the results of applying these methods are recapitulate, as well as the essential Newtonian theory of (disk) galaxy rotation curves. Expand
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


Dwarf galaxy rotation curves and the core problem of dark matter haloes
ABSTRA C T The standard cold dark matter (CDM) model has recently been challenged by the claim that dwarf galaxies have dark matter haloes with constant-density cores, whereas CDM predicts haloesExpand
Constraints on the structure of dark matter halos from the rotation curves of low surface brightness galaxies
We reexamine the disk-halo decompositions of the rotation curves of low surface brightness (LSB) galaxies with Vmax ≥ 80 km s-1, taking full account of the effects of beam smearing. We show that theExpand
Extended rotation curves of spiral galaxies: dark haloes and modified dynamics
Strict criteria are applied to the sample of spiral galaxies with measured rotation curves in order to select those objects for which the observed rotation curve is an accurate tracer of the radialExpand
The Cores of dark matter dominated galaxies: Theory versus observations
We use the rotation curves of a sample of dark matter-dominated dwarf and low surface brightness (LSB) late-type galaxies to study their radial mass distributions. We find that the shapes of theExpand
Simulating observations of dark matter dominated galaxies: towards the optimal halo profile
Low surface brightness galaxies are dominated by dark matter, and their rotation curves thus reflect their dark matter distribution. Recent high-resolution rotation curves suggest that their darkExpand
The extended rotation curve and the dark matter halo of M33
We present the 21-cm rotation curve of the nearby galaxy M33 out to a galactocentric distance of 16 kpc (13 disk scale-lengths). The rotation curve keeps rising out to the last measured point andExpand
Dark Baryons and Rotation Curves
The best measured rotation curve for any galaxy is that of the dwarf spiral DDO 154, which extends out to about 20 disk scale lengths. It provides an ideal laboratory for testing the universalExpand
