Radial metal abundance profiles in the intra-cluster medium of cool-core galaxy clusters, groups, and ellipticals [PDF]

, 2017
The hot intra-cluster medium (ICM) permeating galaxy clusters and groups is not pristine, as it has been continuously enriched by metals synthesised in Type Ia (SNIa) and core-collapse (SNcc) supernovae since the major epoch of star formation (z similar ...

Staphylococcus aureus AgrA Modulators From South African Antimicrobial Plants

Chemistry &Biodiversity, EarlyView.
The study workflow utilized validated in silico [molecular docking, fingerprinting, pharmacokinetics prediction, molecular dynamics (MD) simulation, ligand‐protein contact maps] tools to bioprospect a wide variety of metabolites surveyed from South African plants with antimicrobial activities, and target them against the key S.

Test of Cosmic Web-feeding Model for Star Formation in Galaxy Clusters in the COSMOS Field

The Astrophysical Journal
It is yet to be understood how large-scale environments influence star formation activity in galaxy clusters. One recently proposed mechanism is that galaxy clusters can remain star forming when fed by infalling groups and star-forming galaxies from ...

Filaments of galaxies and Voronoi diagrams

Open Astronomy, 2018
The intersections between a spherical shell and the faces of Voronoi polyhedrons are numerically evaluated. The nodes of these intersections are the points that share the same distances from three nuclei.

Multivariate analysis of the globular clusters in M87

, 2015
An objective classification of 147 globular clusters in the inner region of the giant elliptical galaxy M87 is carried out with the help of two methods of multivariate analysis.

Characterization of the Cubamyces Menziesii Terpenome

ChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Some Properties of Galaxy Structures

Open Astronomy, 2011
We analysed some properties of galaxies structures based on the PF catalog of galaxy structures (Panko & Flin 2006) and the Tully NBG catalog (Tully 1988).

Extended Radio Emission in the Perhipheral Regions of the Shapley Concentration Core

Galaxies, 2017
The Shapley Concentration (SC) is a galaxy supercluster (few tens of degrees) in the Local Universe (<z>∼0.048) which is currently undergoing cluster mergers and group accretion.

Simulating Groups and the IntraGroup Medium: The Surprisingly Complex and Rich Middle Ground between Clusters and Galaxies

Universe, 2021
Galaxy groups are more than an intermediate scale between clusters and halos hosting individual galaxies, they are crucial laboratories capable of testing a range of astrophysics from how galaxies form and evolve to large scale structure (LSS) statistics

The evolution of the star formation activity per halo mass up to redshift ~1.6 as seen by Herschel [PDF]

, 2012
Aims. Star formation in massive galaxies is quenched at some point during hierarchical mass assembly. To understand where and when the quenching processes takes place, we study the evolution of the total star formation rate per unit total halo mass (Σ ...
