Probing Dark Matter with Strong Gravitational Lensing through an Effective Density Slope [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Many dark matter (DM) models that are consistent with current cosmological data show differences in the predicted (sub)halo mass function, especially at sub-galactic scales, where observations are challenging due to the inefficiency of star formation ...

Strong gravitational lensing with the SKA [PDF]
New Astronomy Reviews, 2015 Strong gravitational lenses provide an important tool to measure masses in the distant Universe, thus testing models for galaxy formation and dark matter; to investigate structure at the Epoch of Reionization; and to measure the Hubble constant and possibly w as a function of redshift.

Strong gravitational lensing by rotating Simpson-Visser black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We investigate strong field gravitational lensing by rotating Simpson-Visser black hole, which has an additional parameter (0 ≤ l/2M ≤ 1), apart from mass (M) and rotation parameter (a).

Investigating strong gravitational lensing effects by supermassive black holes with Horndeski gravity [PDF]
The European Physical Journal C, 2021 We study gravitational lensing in strong-field limit by a static spherically symmetric black hole in quartic scalar field Horndeski gravity having additional hair parameter q, evading the no-hair theorem.

Gravitational Lensing of Acoustic Charged Black Holes
The Astrophysical Journal, 2023 We study the gravitational lensing of acoustic charged black holes in strong and weak field limit approximations. For this purpose, we first numerically obtain the deflection limit coefficients and deflection angle in the strong field limit.

Geometric Outlines of the Gravitational Lensing and Its Astronomic Applications
Universe, 2023 Gravitational lensing is a topic of great application value in the field of astronomy. The properties and research methods of gravitational lensing are closely related to the geometric and relativistic characteristics of the background universe.

A Highly Magnified Gravitationally Lensed Red QSO at z = 2.5 with a Significant Flux Ratio Anomaly
The Astrophysical Journal, 2023 We present the discovery of a gravitationally lensed dust-reddened QSO at z = 2.517, identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging reveals a quadruply lensed system in a cusp configuration, with a maximum image ...
