The evolution of groups and clusters [PDF]
arXiv, 1999 Using high resolution N-body simulations we have studied the formation and evolution of clusters and groups in a LCDM cosmological model. Groups of galaxies have been formed already before z=4. The total number of small bound systems and the total number of galaxies in these small systems rapidly decreases after z=1.5. The fraction of isolated galaxies

, 2013 We compile a sample of X-ray-selected galaxy groups and clusters from the XMM-Newton serendipitous source catalogue (2XMMi-DR3) with optical confirmation and redshift measurement from the Sloan Digital Sky Survey (SDSS). The X-ray cluster candidates were

Engineering Gypsophila elegans hairy root cultures to produce endosomal escape‐enhancing saponins
Plant Biotechnology Journal, EarlyView.Summary The limited cytosolic delivery of DNA and protein‐based therapeutics due to endosomal entrapment reduces drug efficacy, increasing treatment costs and possible side effects in human and veterinary medicine as a consequence of higher administered dosages.

A Role for the Plastidial GPT2 Translocator in the Modulation of Lignin Biosynthesis
Plant, Cell &Environment, EarlyView.ABSTRACT Engineering plants with reduced lignin content can result in pleiotropic growth defects. In stems of Arabidopsis plants with reduced expression of hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT), the plastidial glucose 6‐phosphate: phosphate co‐transporter GPT2 is highly overexpressed, and this coincides with reduced lignin ...

, 2017 The X-ray regime, where the most massive visible component of galaxy clusters, the intra cluster medium (ICM), is visible, offers directly measured quantities, like the luminosity, and derived quantities, like the total mass, to characterize these ...

Peace &Change, EarlyView.ABSTRACT This article examines a silence in the histories of the formation of peace and conflict studies as an academic field, focusing on the elision of a female‐identified academic: Gladdys Esther Muir. Muir occasionally appears in histories as a datapoint in peace education chronologies where she is listed as the director of the first peace studies ...

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 ...

Caxton's Afterlife in Manuscript (c.1475‐c.1500)
Renaissance Studies, EarlyView.Abstract At least thirty‐five manuscript copies of Caxton's prints have been found so far. This article explores the implications of such manuscript copies of Caxton's prints and, interrupting the linear history of the book, considers Caxton's appeal beyond print in manuscript.

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
