A statistical study of the luminosity gap in galaxy groups
, 2010 The luminosity gap between the two brightest members of galaxy groups and clusters is thought to offer a strong test for the models of galaxy formation and evolution.

The Outer Halos of Very Massive Galaxies: BCGs and their DSC in the Magneticum Simulations
Galaxies, 2017 Recent hydrodynamic cosmological simulations cover volumes up to Gpc 3 and resolve halos across a wide range of masses and environments, from massive galaxy clusters down to normal galaxies, while following a large variety of physical processes ...

Chandra Studies of the X-ray Gas Properties of Fossil Systems
, 2015 We study ten galaxy groups and clusters suggested in the literature to be "fossil system (FS)" based on \chandra\ observations. According to the $M_{500}-T$ and $L_{\rm X}-T$ relations, the gas properties of FSs are not physically distinct from ordinary ...

Mass‐to‐Light Ratios of Groups and Clusters of Galaxies [PDF]
The Astrophysical Journal, 2000 We constrain the mass-to-light ratios, gas mass fractions, baryon mass fractions and the ratios of total to luminous mass for a sample of eight nearby relaxed galaxy groups and clusters: A262, A426, A478, A1795, A2052, A2063, A2199 and MKW4s. We use ASCA spatially resolved spectroscopic X-ray observations and ROSAT PSPC images to constrain the total ...

The baryon content of groups and clusters of galaxies in the FABLE simulations [PDF]
, 2019 We study the gas and stellar mass content of galaxy groups and clusters in the FABLE suite of cosmological hydrodynamical simulations, including the evolution of their central brightest cluster galaxies (BCGs), satellite galaxies and intracluster light ...

Journal of Heterocyclic Chemistry, EarlyView.Highly selective oxidation of thiazolidin‐4‐ones to sulfoxides and sulfones with Oxone and KMnO4, respectively. ABSTRACT S‐Oxidation of 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐ones with Oxone was investigated. For all compounds evaluated, selective oxidation to the sulfoxide versus the sulfone was realized using 3 equivalents of Oxone at room ...

Somato‐Cognitive Action Network in Focal Dystonia
Movement Disorders, EarlyView.Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Journal of Polymer Science, EarlyView.Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...
