Cosmic web dynamics: forces and strains

Monthly Notices of the Royal Astronomical Society
ABSTRACT This study concerns an inventory of the gravitational force and tidal field induced by filaments, walls, cluster nodes, and voids on megaparsec scales and how they assemble and shape the cosmic web. The study is based on an N$_{\rm Part}=512^3$ Lambda-cold dark matter dark matter only N-body simulation in a (300$h^{-1}$ Mpc)$^

Magnetic Fields in Galaxy Clusters and in the Large-Scale Structure of the Universe

Galaxies, 2018
The formation and history of cosmic magnetism is still widely unknown. Significant progress can be made through the study of magnetic fields properties in the large-scale structure of the Universe: galaxy clusters, filaments, and voids of the cosmic web.

Land, Gendered Labor, and Empire‐Making in Central Sudan

American Anthropologist, EarlyView.
ABSTRACT This article offers an ethnographic analysis of Gulf Arab empire‐making in central Sudan, focusing on an Emirati‐owned farm in the Gezira region as a key site of capitalist extraction and imperial ambition. Through three overlapping vantage points—farm, port, and body—it explores how Emirati investments in Sudanese land, infrastructure, and ...

Breathing in Plants and Chaos—Cosmic Tree Events in Cameroon and Beyond

Anthropology of Consciousness, EarlyView.
ABSTRACT Contemporary practices of tapping into the wisdom of ancestral trees are described through three entangled recent events lived within the context of Bantu practices in Cameroon. In the three instances, the steered or chance encounters with high potency trees were serendipitous telling moments which brought something new to the horizon.

Differentiable fuzzy cosmic web for field-level inference

Astronomy & Astrophysics
Context. A comprehensive analysis of the cosmological large-scale structure derived from galaxy surveys involves field-level inference, which requires a forward-modelling framework that simultaneously accounts for structure formation and tracer bias ...

AlpIce‐1: a database of geochronological and geomorphological constraints on Alps‐wide palaeoglacier fluctuations between the Last Glacial Maximum and the Holocene

Boreas, EarlyView.
The AlpIce‐1 database is the first compilation of published geomorphological and geochronological markers constraining build‐up, culmination and decay of glaciers from the Last Glacial Maximum through the Holocene across the entire European Alps. AlpIce‐1 integrates more than 4200 surface‐exposure and radiocarbon ages, homogenized, quality controlled ...

Liquid Biopsy and Multi‐Cancer Early Detection Tests for Cancer Screening: A Scoping Review

Clinical Genetics, EarlyView.
There is a large body of evidence on liquid biopsy and multi‐cancer detection tests for cancer screening. Most studies addressed test performance outcomes, while fewer addressed clinical outcomes, implementation, and cost‐effectiveness. No studies evaluated cancer mortality.

Cosmic strings and scalar tensor gravity [PDF]

, 1999
This thesis is concerned with the study of cosmic strings. We studied the values for the Higgs mass and string coupling for which the gravitational effect of an infinite cosmic string in the context of the Einstein theory is not only locally but also ...
