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.

Comparative Analysis of Lavandula Dentata Rhizosphere Microbiota Across Different Developmental Stages in a Semi‐Arid Area

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This study aims to give deeper insight into the relationship between the dynamics of the rhizospheric microbiota and the developmental stages of L. dentata growing spontaneously in a semi‐arid environment. To achieve this objective, we examined and monitored the biomass (using phospholipid fatty acid, PLFA analysis), diversity and network complexity of

Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

SDSS-IV MaNGA: faint quenched galaxies – I. Sample selection and evidence for environmental quenching [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched galaxies exhibit coherent rotation in their stellar kinematics. Our sample includes all 39 quenched low-mass galaxies observed in the first year of MaNGA.

Gas Loss by Ram Pressure Stripping and Internal Feedback From Low Mass Milky Way Satellites

, 2016
The evolution of dwarf satellites of the Milky Way is affected by the combination of ram pressure and tidal stripping, and internal feedback from massive stars.

Theoretical and Experimental Investigations of Acetal Formation During the Oxidation of Xylose to Formic Acid Catalysed by H5PV2Mo10O40 in Methanolic‐Aqueous Solution

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
The substrate‐solvent interactions play a major role in the modified OxFA process. Herein, the formation and stability of several reaction intermediates via acetalization depending on solvent composition and reaction conditions is investigated. The BioValCat (Enhanced Biomass Valorization by Engineering of Polyoxometalate Catalysts) project aims at ...

TwO Parameters Semi Empirical Model (TOPSEM): Galaxy Evolution and Bulge/Disk Dicothomy from Two-stage Halo Accretion

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

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Mitogenomic Characterization and Phylogenetic Expansion of Tribe Coccinellini (Coleoptera: Coccinellidae)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study presents the complete mitochondrial genomes of nine ladybird species from the tribe Coccinellini and compares them with 58 previously published mitogenomes. Phylogenetic analyses confirm the taxonomic placement of these species within Coccinellini.
