A dichotomy in satellite quenching around L* galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We examine the star formation properties of bright (~0.1 L*) satellites around isolated ~L* hosts in the local Universe using spectroscopically confirmed systems in the Sloan Digital Sky Survey DR7. Our selection method is carefully designed with the aid of N-body simulations to avoid groups and clusters.

The Astrophysical JournalWe present the star-forming properties of 378 satellite galaxies around 101 Milky Way analogs in the Satellites Around Galactic Analogs (SAGA) Survey, focusing on the environmental processes that suppress or quench star formation.

The Astrophysical Journal, 2023 In recent years, increasing attention has been devoted to semi-empirical, data-driven models to tackle some aspects of the complex and still largely debated topic of galaxy formation and evolution. We here present a new semi-empirical model whose marking

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

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.

Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time
The Astrophysical JournalIn a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar ...

Analytical Science Advances, Volume 6, Issue 2, December 2025.ABSTRACT A novel micro‐array was developed to a colorimetric detection of some amines, including histamine (HT), cadaverine (CAD), 1,4‐diaminobutane (putrescine), 2‐phenylethylamine (2‐PEA), spermidine (SD) and ethylenediamine (EA) using silver nanoparticle (silver nanoprisms [AgNPrs]) as optical nanoprobe.

Galaxy quenching in various environments
, 2023 Already early studies of the morphology-density relation of galaxies showed that early-type galaxies lie in the centres of rich clusters, and in small groups in filaments between clusters, where they are located closer to filament axis than late-type galaxies. This means that galaxies are indeed pre-processed in groups. In our present study we searched

Ecography, Volume 2025, Issue 12, December 2025.Developing species distribution models (SDMs) requires high‐quality species occurrence records. These records, stemming from various sources with different sampling procedures, are often archived in open‐access databases, making automated data quality checks inevitable.
