In the standard flat cosmological constant (A) cold dark matter (CDM) cosmology, a model of two populations of lens halos for strong gravitational lensing can reproduce the results of the Jodrell-Bank VLA Astrometric Survey (JVAS) and the Cosmic Lens All-Sky Survey (CLASS) radio survey. In such a model, lensing probabilities are sensitive to three parameters: the concentration parameter c 1 , the cooling mass scale M c and the value of the CDM power spectrum normalization parameter σ 8 .

Gravitational lensing effects on submillimetre galaxy counts
We study the effects on the number counts of submillimetre galaxies due to gravitational lensing. We explore the effects on the magnification cross-section due to halo density profiles, ellipticity
Strong Lensing Probability for Testing TeVeS Theory
We calculate the strong lensing probability as a function of the image separation ?? in TeVeS (tensor-vector-scalar) cosmology, which is a relativistic version of MOND (MOdified Newtonian Dynamics).

Concordance of Kinematics and Lensing of Elliptical Galaxies with WMAP Cosmology
We explore degeneracies in strong lensing model so to make time de- lay data consistent with the WMAP (Wilkinson Microwave Anisotropy Probe) cos- mology. Previous models using a singular isothermal
Observational constraints on low redshift evolution of dark energy: How consistent are different observations?
The dark energy component of the Universe is often interpreted either in terms of a cosmological constant or as a scalar field. A generic feature of the scalar field models is that the equation of
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

Properties of wide‐separation lensed quasars by clusters of galaxies in the Sloan Digital Sky Survey
We use high-resolution N-body numerical simulations to study the number of predicted large-separation multiply imaged systems produced by clusters of galaxies in the Sloan Digital Sky Survey (SDSS)
Generalized Chaplygin gas as a unified scenario of dark matter/energy: Observational constraints
Although various cosmological observations congruously suggest that our universe is dominated by two dark com- ponents, the cold dark matter without pressure and the dark energy with negative
f(R) gravity theories in the Palatini formalism constrained from strong lensing
f(R) gravity, capable of driving the late-time acceleration of the universe, is emerging as a promising alternative to dark energy. Various f(R) gravity models have been intensively tested against


Strong gravitational lensing and dark energy
We investigate the statistics of gravitational lenses in flat, low-density cosmological models with different cosmic equations of state ω. We compute the lensing probabilities as a function of image

The lensing probabilities of quasars with image separations greater than Δθ and flux density ratios less than qr are calculated by foreground dark matter halos in a flat, cosmological

We use the semianalytical approach to analyze gravitational lensing of remote quasars by foreground dark halos in various cold dark matter (CDM) cosmologies in order to determine the sensitivity of
Gravitational Lensing by a Compound Population of Halos: Standard Models
Based on observed rotation curves of galaxies and theoretical simulations of dark matter halos, there are reasons for believing that at least three different types of dark matter halos exist in the

The statistics of wide-separation (6'' < θ < 15'') gravitational lenses constrain the amount of mass in the cores of dark matter halos on group and cluster mass scales. For a family of halo models
Gravitational Lensing of Distant Supernovae in Cold Dark Matter Universes
Ongoing searches for supernovae (SNe) at cosmological distances have recently started to provide large numbers of events with measured redshifts and apparent brightnesses. Compared to quasars or

We investigate how central black holes (BHs) in galactic dark halos could affect strong gravitational lensing. The distribution of integral lensing probability with image separations are calculated

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 the Inner Mass Profiles of Lensing Galaxies from Missing Odd Images
Most gravitational lens systems consist of two or four observable images. The absence of detectable odd images allows us to place a lower limit on the power-law slope of the inner mass profile of
Constraints on the Baryonic Compression and Implications for the Fraction of Dark Halo Lenses
We predict the fraction of dark halo lenses, that is, the fraction of lens systems produced by the gravitational potential of dark halos, on the basis of a simple parametric model of baryonic
