Formation of Groups and Clusters of Galaxies
, 1998 The formation, inner properties, and spatial distribution of galaxy groups and clusters are closely related to the background cosmological model. We use numerical simulations of variants of the CDM model with different cosmological parameters and distinguish relaxed objects from recent mergers using the degree of virialisation.

Animal Genetics, Volume 57, Issue 1, February 2026.Abstract Previous studies have identified genetic loci that are associated with both feed conversion efficiency and gut microbiota in chickens, suggesting that interactions between the host genome and gut microbiota may influence chicken growth. However, the number of microbial QTL and gut microbiota associated with chicken body weight remains largely ...

Cladistics, Volume 42, Issue 1, Page 25-45, February 2026.Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

Distribution of Merging and Post-merger Galaxies in Nearby Galaxy Clusters
The Astrophysical JournalWe study the incidence and spatial distribution of galaxies that are currently undergoing gravitational merging (M) or that have signs of being post-merger (PM) in six galaxy clusters (A754, A2399, A2670, A3558, A3562, and A3716) within the redshift ...

Robust Detection of Hot Intragroup Medium in Optically Selected, Poor Galaxy Groups by eROSITA
The Astrophysical Journal LettersOver the last several decades, extensive research has been conducted on the baryon cycles within cosmic structures, encompassing a broad mass range from dwarf galaxies to galaxy clusters. However, a notable gap in understanding the cosmic baryon cycle is
