Cluster Lensing Mass Inversion (CLUMI+): Combining Dynamics and Weak Lensing around Galaxy Clusters

open access: yesThe Astrophysical Journal
We present clumi+ , a self-consistent, multiprobe methodology for reconstructing the mass distribution in and around galaxy clusters by combining gravitational lensing and dynamical observations. Building on the joint likelihood framework of K.

Gravitational lensing phenomena of Ellis-Bronnikov-Morris-Thorne wormhole with global monopole and cosmic string

open access: yesPhysics Letters B
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.

Gravitational Lenses

open access: yes, 1999
The purpose of these lecture notes is to describe the gravitational lens effects in different astrophysical contexts. These notes are voluntarily focused on the fundamental mechanisms and the basic concepts that are useful to describe these effects. The observational consequences are presented in more details in accompanying notes by Y. Mellier.

Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting

open access: yesSmall, EarlyView.
A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.

Using Convolutional Neural Networks to Search for Strongly Lensed Quasars in KiDS DR5

open access: yesThe Astrophysical Journal
Gravitationally strongly lensed quasars (SL-QSO) offer invaluable insights into cosmological and astrophysical phenomena. With the data from ongoing and next-generation surveys, thousands of SL-QSO systems can be discovered expectedly, leading to ...

Gravitational Lenses [PDF]

open access: yesSymposium - International Astronomical Union, 1988
The gravitational lensing phenomenon is a new observational tool in cosmology. It appears to occur reasonably frequently; several thousand examples probably are observable with current radio and optical telescopes. A dozen or so reasonable candidates have been proposed, but it has become clear that one must apply strong tests to distinguish between ...

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

open access: yesSmall, EarlyView.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

The Biased Interaction Game: A System Theoretic Approach to the Emergence of Inequality, Hierarchy, and the Implications for the Likelihood of Cooperation

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT The emergence of cooperation in natural selection has been successfully studied using game theory and, despite the underlying selfish nature of the evolutionary process, a spectrum of plausible mechanisms have been proposed to determine the conditions under which cooperative behaviour is likely to occur.
