Gas in Groups and Clusters of Galaxies [PDF]

Astrophysics and Space Science, 2004
Groups and clusters contain a large fraction of hot gas which emits X-ray radiation. This gas yields information on the dynamical state and on the total mass of these systems. X-ray spectra show that heavy elements are present in the gas. As these metals must have been produced in the cluster/group galaxies and later transported into the gas, the ...

Epidemiology and Genetics of Rheumatic Diseases Suggest a Constant Rate of DNA Damage as Underlying Cause

Immunology, EarlyView.
A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should

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 ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Evolution of the Physical Properties of the Most Massive Galaxies in Clusters and Their Protohalos

The Astrophysical Journal
We investigated the evolution of the physical properties of the brightest galaxies in clusters and their protohalos from z = 4 to z = 0. Galaxy clusters and groups are identified using a halo-based group finder applied to the COSMOS2020 galaxy catalog ...

A Proof‐of‐Concept Study of Gamified Rhythmic Training in Preadolescents Who Stutter

Annals of the New York Academy of Sciences, EarlyView.
ABSTRACT Stuttering is a developmental speech fluency disorder linked to timing deficits in speech motor control. Given the shared neural mechanisms between rhythmic timing and speech production, rhythm‐based interventions may hold promise for stuttering.

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.

Active Galactic Nucleus Properties of ∼1 Million Member Galaxies of Galaxy Groups and Clusters at z < 1.4 Based on the Subaru Hyper Suprime-Cam Survey

The Astrophysical Journal
Herein, we present the statistical properties of active galactic nuclei (AGNs) for approximately 1 million member galaxies of galaxy groups and clusters with 0.1 < cluster redshift ( z _cl ) < 1.4 selected using the Subaru Hyper Suprime-Cam, the so ...

Galaxy groups in the presence of cosmological constant: Increasing the masses of groups

Physics Letters B
The boundaries of galaxy groups and clusters are defined by the interplay between the Newtonian attractive force and the decoupling from the local expansion of the Universe.
