Gravitational lensing around Kehagias–Sfetsos compact objects surrounded by plasma
We study the optical properties of the Kehagias–Sfetsos (KS) compact objects, characterized by the “Hořava” parameter $$\omega _{_{KS}}$$ ωKS , in the presence of plasma, considering its homogeneous or power-law density distribution.

Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Weak-lensing Mass Bias in Merging Galaxy Clusters
Although weak lensing (WL) is a powerful method to estimate a galaxy cluster mass without any dynamical assumptions, a model bias can arise when the cluster density profile departs from the assumed model profile. In a merging system, the bias is expected

Weak gravitational lensing Schwarzschild-MOG black hole in plasma
This paper is devoted to study weak gravitational lensing properties around black hole surrounded plasma medium in modified gravity (MOG). We have investigated the effects of the MOG-parametr and plasma medium on the deflection angle and total ...

Cluster Weak Gravitational Lensing
Weak gravitational lensing of background galaxies is a unique, direct probe of the distribution of matter in clusters of galaxies. We review several important aspects of cluster weak gravitational lensing together with recent advances in weak lensing techniques for measuring cluster lensing profiles and constraining cluster structure parameters.

Microlensing timescales and flux magnification probabilities of a sample of 204 lensed quasars
Context. Quasar microlensing is a very useful tool in cosmology and astrophysics, as well as a source of uncertainty in certain investigations, such as the determination of the Hubble constant from lensed quasars.

Beyond the Einstein–Maxwell model, electromagnetic field might couple with gravitational field through the Weyl tensor. In order to provide one of the missing puzzles of the whole physical picture, we investigate weak deflection lensing for photons ...

Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.
