We investigate the gravitational lensing properties of dark matter halos with Burkert profiles. We derive an analytic expression for the lens equation and use it to compute the magnification, impact parameter, and image separations for strong lensing. For the scaling relation that provides the best fits to spiral galaxy rotation curve data, Burkert halos will not produce strong lensing, even if this scaling relation extends up to masses of galaxy clusters. Tests of a simple model of an…

Cusp-core problem and strong gravitational lensing
Cosmological numerical simulations of galaxy formation have led to the cuspy density profile of a pure cold dark matter halo toward the center, which is in sharp contradiction with the observations
Strong Gravitational Lensing by Wave Dark Matter Halos
Wave Dark Matter (WaveDM) has recently gained attention as a viable candidate to account for the dark matter content of the Universe. In this paper we explore the extent to which dark matter halos in
Dark matter scaling relations in intermediate z haloes
We investigate scaling relations between the dark matter (DM) halo model parameters for a sample of intermediate-redshift early-type galaxies (ETGs) resorting to a combined analysis of Einstein radii
Wave dark matter as a gravitational lens for electromagnetic and gravitational waves
The majority of the matter in the known universe is believed to be in the form of Dark Matter, and its widely accepted description is done by Cold Dark Matter (CDM). Nevertheless, its exact
Scalar field haloes as gravitational lenses
A non-topological soliton model with a repulsive scalar self-interaction of the Emden type provides a constant-density core, similarly as the empirical Burkert profile of dark matter (DM) haloes. As
Astrophysics in 2003
Five coherent sections appear this year, addressing solar physics, cosmology (with WMAP highlights), gamma-ray bursters (and their association with Type Ia supernovae), extra-solar-system planets,


Dark Matter Scaling Relations
We investigate the structure of dark matter halos by means of the kinematics of a very large sample of spiral galaxies of all luminosities. The observed rotation curves show a universal profile which
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. Regardless
Cold Dark Matter and Strong Gravitational Lensing: Concord or Conflict?
Using the number and sizes of observed gravitational lenses, I derive upper limits on the dark matter content of elliptical galaxies. On average, dark matter can account for no more than 33% of the
Constraints on dark matter physics from dwarf galaxies through galaxy cluster haloes
One of the predictions of the standard cold dark matter model is that dark haloes have centrally divergent density profiles. An extensive body of rotation curve observations of dwarf and low surface
The dark matter distribution in disc galaxies
We use high-quality optical rotation curves of nine low-luminosity disc galaxies to obtain the velocity profiles of the surrounding dark matter haloes. We find that they increase linearly with radius
CDM and Strong Lensing: Concord or Conflict?
(Abridged) Using the number and sizes of observed gravitational lenses, I derive upper limits on the dark matter content of elliptical galaxies. Galaxies built from Cold Dark Matter (CDM) mass
The Dark Matter Density Profile of the Lensing Cluster MS 2137–23: A Test of the Cold Dark Matter Paradigm*
We present new spectroscopic observations of the gravitational arcs and the brightest cluster galaxy (BCG) in the cluster MS 2137-23 (z = 0.313) obtained with the Echelle Spectrograph and Imager on
On the Radial Density Profile of Intracluster Gas Tracing the Isothermal Dark Halo with a Finite Core
The cusped Navarro, Frenk, & White (NFW) universal density profile suggested by typical cold dark matter (CDM) models has been challenged in recent years by the discovery of soft cores with finite
Hα Rotation Curves: The Soft Core Question
We present high-resolution Hα rotation curves of four late-type dwarf galaxies and two low surface brightness (LSB) galaxies, for which accurate H I rotation curves are available from the literature.
A Spectroscopic Redshift for the Cl 0024+16 Multiple Arc System: Implications for the Central Mass Distribution.
A spectroscopic redshift of z=1.675 is presented for the well-known multiply lensed system of arcs seen in the z=0.39 cluster Cl 0024+16.39, suggesting that the most significant minima of the cluster potential are not dynamically erased.
