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

The 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.

GLASS: Generator for Large Scale Structure

The Open Journal of Astrophysics, 2023
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 ...

Intuition–Driven Prospection and Uncertainty Misalignment: Sources of Entrepreneurial Agency Problems in Ventures

Strategic Change, EarlyView.
ABSTRACT Start‐up CEOs are usually more aligned with the interests of the venture board compared to CEOs in legacy firms, and therefore it is usual to conclude that the traditional agency problem is lower in ventures. In this article, it is argued that this is only half of the story, and that the agency problem is reversed in early ventures such that ...

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

Nano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Weak lensing of large scale structure in the presence of screening

, 2015
A number of alternatives to general relativity exhibit gravitational screening in the non-linear regime of structure formation. We describe a set of algorithms that can produce weak lensing maps of large scale structure in such theories and can be used ...

The Measurement‐Impact Gap: A Bibliometric Diagnosis of Development Finance Institutions and SDG Research

Sustainable Development, EarlyView.
ABSTRACT The role of Development Finance Institutions (DFIs) in achieving the Sustainable Development Goals (SDGs) is a topic of growing scholarly importance. While existing literature has mapped the thematic scope of this field, a critical diagnosis of its intellectual structure and inherent biases is missing.

Forecasting the Detection of Lyman-alpha Forest Weak Lensing from the Dark Energy Spectroscopic Instrument and Other Future Surveys

The Open Journal of Astrophysics
The apparent angular positions of quasars are deflected on the sky by the gravitational field sourced by foreground matter. This weak lensing effect is measurable through the distortions it introduces in the lensed quasar spectra.

Probing a regular non-minimal Einstein-Yang-Mills black hole with gravitational lensings

Physics Letters B, 2019
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.

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

Systems 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.
