Weak gravitational lensing by Bocharova–Bronnikov–Melnikov–Bekenstein black holes using Gauss–Bonnet theorem [PDF]
The European Physical Journal Plus, 2020 In this article, we demonstrate the weak gravitational lensing in the context of Bocharova–Bronnikov–Melnikov–Bekenstein (BBMB) black hole. To this desire, we derive the deflection angle of light in a plasma medium by BBMB black hole using the Gibbons ...

Weak gravitational lensing in fourth order gravity [PDF]
Physical Review D, 2012 For a general class of analytic $f(R,R_{αβ}R^{αβ},R_{αβγδ}R^{αβγδ})$ we discuss the gravitational lensing in the Newtonian Limit of theory. From the properties of Gauss Bonnet invariant it is successful to consider only two curvature invariants between the Ricci and Riemann tensor.

Radio weak gravitational lensing with VLA and MERLIN [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We carry out an exploratory weak gravitational lensing analysis on a combined VLA and MERLIN radio data set: a deep (3.3 micro-Jy beam^-1 rms noise) 1.4 GHz image of the Hubble Deep Field North. We measure the shear estimator distribution at this radio sensitivity for the first time, finding a similar distribution to that of optical shear estimators ...

Periodontology 2000, EarlyView., 2023 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.

Cluster Weak Gravitational Lensing
International School of Physics “Enrico Fermi”, 2010 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.

, 2010 The galaxy intrinsic alignment is a severe challenge to precision cosmic shear measurement. We propose self-calibrating the induced gravitational shear-galaxy intrinsic ellipticity correlation (the GI correlation) in weak lensing surveys with photometric
