The cosmic microwave background (CMB) represents a unique source for the study of gravitational lensing. It is extended across the entire sky, partially polarized, located at the extreme distance of z=1100, and is thought to have the simple, underlying ...

Current status of weak gravitational lensing
Weak gravitational lensing of distant galaxies by foreground structures has proven to be a powerful tool to study the mass distribution in the universe. Nowadays, attention has shifted from clusters of galaxies to the statistical properties of the large scale structures and the halos of (field) galaxies. These applications have become feasible with the

Weak gravitational lensing with CO galaxies [PDF]
Optical weak lensing surveys have become a powerful tool for precision cosmology, but remain subject to systematic effects that can severely bias cosmological parameter estimates if not carefully removed. We discuss the possibility of performing complementary weak lensing surveys at radio/microwave frequencies, using detections of CO-emitting galaxies ...

Biased Dark Energy Constraints from Neglecting Reduced Shear in Weak Lensing Surveys [PDF]
The weak gravitational lensing of distant galaxies by large-scale structure is expected to become a powerful probe of dark energy. By measuring the ellipticities of large numbers of background galaxies, the subtle gravitational distortion called "cosmic ...

A Methodological Framework to Study Change in Team Cognition Under the Dynamical Hypothesis
Abstract The dynamical hypothesis claims that cognitive systems, such as teams, are dynamical systems (i.e., an interdependent collection of individuals and their technology that change together over time). Following this hypothesis, team researchers have adopted dynamical approaches to better understand the team cognitive processes and states that ...

GLASS: Generator for Large Scale Structure
We present GLASS, the Generator for Large Scale Structure, a new code for the simulation of galaxy surveys for cosmology, which iteratively builds a light cone with matter, galaxies, and weak gravitational lensing signals as a sequence of nested shells ...

Inverted PAINT for Material‐Specific Super‐Resolution Fluorescence Imaging of Semiconductors
This study presents Inverted PAINT, a label‐free super‐resolution fluorescence imaging method optimized for thick and non‐transparent semiconductor materials. By employing electrostatic dye–surface interactions in an inverted geometry, the technique enables material‐specific, multicolor, and 3D nanoscale imaging, with applications in semiconductor ...

In this paper, we theoretically investigate gravitational lensing within the space-time framework of traversable wormholes, focusing on the combined effects of a global monopole and a cosmic string.

Probing a regular non-minimal Einstein-Yang-Mills black hole with gravitational lensings
We investigate weak and strong deflection gravitational lensings of the regular black hole predicted by a non-minimal Einstein–Yang–Mills theory. We find that its weak deflection lensing is the same as a Reissner–Nordström black hole's.
