VERY ISOLATED EARLY-TYPE GALAXIES

, 2003
We use the Karachentseva Catalogue of Very Isolated Galaxies to investigate a candidate list of more than 100 very isolated early-type galaxies. Broadband imaging and low-resolution spectroscopy are available for a large fraction of these candidates and ...

Minor-merger-induced Star Formation Rejuvenation in an Elliptical Radio-loud Quasar Host, 3C 59

The Astrophysical Journal
We report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies.

An Integrated Transient Expression and UPLC‐PDA Approach for Functional Genomics and Metabolic Analysis of Cannabis sativa

Biotechnology Journal, Volume 21, Issue 10, October 2026.
Graphical Abstract and Lay Summary Cannabis research is limited by a lack of efficient tools for studying gene function and metabolism. We developed two rapid, high‐efficiency methods for transient gene expression in high‐THC Cannabis and a simple, cost‐effective method to measure cannabinoids and cannflavins.

Luminosity Evolution of the Hot Gas in Normal Galaxies from the Near Universe to z = 0.5

The Astrophysical Journal
We explore the evolution of the ∼10 ^7 K hot gas in normal galaxies out to redshift = 0.5 (lookback time = 5 Gyr), using X-ray luminosity functions (XLFs) built from a sample of 575 normal galaxies with z < 0.6 detected in five high-galactic-latitude ...

The Correlation Luminosity-Velocity Dispersion of Galaxies and Active Galactic Nuclei

Universe
In this work we discuss the correlation between luminosity L and velocity dispersion σ observed in different astrophysical contexts, in particular that of early-type galaxies (ETGs; Faber–Jackson (FJ) law) and that of active galactic nuclei (AGN).

High‐Quality Annotated ZZ Male Genome Assembly of Eulimnadia texana

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Androdioecious crustaceans in the genus Eulimnadia have a unique sex‐determining system that allows examination of evolutionary models of early sex chromosome evolution. Although there is a high‐quality assembly of WW hermaphrodites, there is no complementary high‐quality male (ZZ) genome assembly yet for E. texana.

The Genome of an Ocean Wanderer: A High‐Quality Long‐Read Reference Genome for the Trindade Petrel (Pterodroma arminjoniana)

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We present the first whole‐genome assembly for the Trindade petrel (Pterodroma arminjoniana), a wide‐ranging procellariiform seabird of conservation and eco‐evolutionary importance. These resources provide a reference‐quality genome for future studies of taxonomy and systematics, morphology, hybridisation, gene flow, population structure, conservation ...

The nature of early-type galaxies

, 2018
I will give a personal view of the development of our understanding of the nature of early-type galaxies over the last 40 years, focusing particularly on the dynamics and highlighting the role played by Tim de ...

Trp53 Deficiency Increases the Frequency of Hprt Mutant T Lymphocytes Following High‐LET Iron Particle Irradiation of Mice

Environmental and Molecular Mutagenesis, Volume 67, Issue 8-9, October-November 2026.
ABSTRACT Charged particles like iron‐56 ions impose health risks in long‐term manned space exploration. This study was designed to define the impact of Trp53 status upon the manifestation of mutations in the hypoxanthine‐guanine phosphoribosyltransferase (Hprt) gene in splenic T‐cells following exposure of Trp53 wild‐type, hemizygous, and nullizygous ...
