The Way to Quench: Galaxy Evolution in A2142

Research in Astronomy and Astrophysics, 2023
Abstract We show how the star formation activity of galaxies is progressively inhibited from the outer region to the center of the massive cluster A2142. From an extended spectroscopic redshift survey of 2239 galaxies covering a circular area of radius ∼11 Mpc from the cluster center, we extract a sample of 333 galaxies with known ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

THE MASS DEPENDENCE OF DWARF SATELLITE GALAXY QUENCHING [PDF]

The Astrophysical Journal, 2014
We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low mass dwarf spheroidals and dwarf irregulars to more massive dwarfs similar to the Magellanic clouds.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

The Distribution of Quenched Galaxies in the Massive z = 0.87 Galaxy Cluster El Gordo

The Astrophysical Journal
El Gordo (ACT-CL J0102−4915) is a massive galaxy cluster with two major mass components at redshift z = 0.87. Using spectral energy distribution fitting results from JWST/NIRCam photometry, the fraction of quenched galaxies in this cluster was measured ...

Dynamical Hotness, Star Formation Quenching, and Growth of Supermassive Black Holes

The Astrophysical Journal, 2023
A stellar system is dynamically hot when its kinetic energy is dominated by random motion represented by the velocity dispersion σ _hot . We use MaNGA data to obtain the inner and outer dispersion of a galaxy, σ _in and σ _out , to characterize its ...

‘A Sort of Armed Argument’: Ireland's Civil War of Words

History, EarlyView.
Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

Machine Learning Classification of COSMOS2020 Galaxies: Quiescent versus Star-forming

The Astrophysical Journal
Accurately distinguishing between quiescent and star-forming galaxies is essential for understanding galaxy evolution. Traditional methods, such as spectral energy distribution (SED) fitting, can be computationally expensive and may struggle to capture ...

Effectiveness of Virtual Reality for Pain Relief in Procedures Related to Obstetrics and Gynaecology: A Systematic Review and Meta‐Analysis of Randomised Controlled Trials

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Immersive virtual reality (VR) technology offers a non‐invasive, non‐pharmacological approach to reduce pain perception in patients undergoing diagnostic or interventional procedures. Objective To systematically evaluate the efficacy of immersive VR technology in reducing pain perception during obstetric and gynaecological ...

Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy–Halo Connection in Simulations

The Astrophysical Journal
Star formation quenching in galaxies plays a crucial role in galaxy evolution and is believed to be driven primarily by galaxy mass and environment.
