Galaxy Zoo: evidence for rapid, recent quenching within a population of AGN host galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We present a population study of the star formation history of 1244 Type 2 AGN host galaxies, compared to 6107 inactive galaxies. A Bayesian method is used to determine individual galaxy star formation histories, which are then collated to visualise the distribution for quenching and quenched galaxies within each population.

Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS

The Astrophysical Journal
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

Genomic Insights and Matrilineal Evolution Reveal Potential Dispersal Patterns of Chitala Species (Osteoglossomorpha: Notopteridae) in the Sundaland Biodiversity Hotspot

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study reports the first complete mitochondrial genome of Chitala borneensis and the re‐sequencing of Chitala lopis from Sundaland. Analyses of genetic structure, matrilineal phylogenies, and TimeTree‐based divergence estimates elucidate the evolutionary history and dispersal dynamics of extant Chitala species.

ELVES. III. Environmental Quenching by Milky Way–mass Hosts

The Astrophysical Journal, 2023
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.

ELUCID IV: Galaxy Quenching and its Relation to Halo Mass, Environment, and Assembly Bias

, 2017
We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large scale environment.

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

Integrative Zoology, Volume 21, Issue 2, Page 359-370, March 2026.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

On the Signature of Black Holes on the Quenched Stellar Mass Function

The Astrophysical Journal
As star-forming galaxies approach or exceed a stellar mass of around 10 ^11 M _⊙ , they are increasingly likely to be quenched in a process generically called mass quenching.

KNaCaSi4O10 Obtained From Crystallization Experiments in the Quaternary System K2O–Na2O–CaO–SiO2

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
The compound KNaCaSi4O10 has been identified in crystallization experiments of glasses in the quaternary system K2O–Na2O–CaO–SiO2 and has undergone structural characterization. Vibrational spectroscopic data have been acquired and interpreted using density functional theory (DFT) calculations.
