gravity theories in the Palatini Formalism constrained from strong lensing
Xin-Juan Yang, Da-Ming Chen
gravity, capable of driving the late-time acceleration of the universe, is emerging as a promising alternative to dark energy. Various gravity models have been intens…
Contradiction between strong lensing statistics and a feedback solution to the cusp/core problem
Da-Ming Chen, Stacy McGaugh
Standard cosmology has many successes on large scales, but faces some fundamental difficulties on small, galactic scales. One such difficulty is the cusp/core problem. High resolut…
Strong lensing probability in TeVeS theory
Da-Ming Chen
We recalculate 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 New…
Strong lensing probability for testing TeVeS theory
Da-Ming Chen, HongSheng Zhao
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…
Nonsingular density profiles of dark matter halos and Strong gravitational lensing
Da-Ming Chen
We use the statistics of strong gravitational lenses to investigate whether mass profiles with a flat density core are supported. The probability for lensing by halos modeled by a…
The amplitude of mass fluctuations and mass density of the Universe constrained by strong gravitational lensing
Da-Ming Chen
We investigate the linear amplitude of mass fluctuations in the universe, , and the present mass density parameter of the Universe, , from the statistical strong…
