A Multiphase Model for the Intracluster Medium [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
Constraints on the clustered mass density \Omega_m of the universe derived from the mean intracluster gas fraction of X-ray clusters may be biased by a single-phase assumption for the thermodynamic structure of the intracluster medium (ICM). We propose a

Intracluster Stars and the Chemical Enrichment of the Intracluster Medium [PDF]

The Astrophysical Journal, 2004
We explore the contribution of intracluster stars (ICS) to the chemical enrichment history of the intracluster medium (ICM). In contrast to scenarios in which all the metals originate in cluster galaxies and are then transported into the ICM, intracluster stars enrich the ICM in situ, thereby contributing 100% of their supernovae ejecta directly into ...

The Enrichment of the Intracluster Medium [PDF]

arXiv, 1996
The enrichment of the intracluster medium (ICM) of galaxy clusters, within the framework of the supernovae-driven wind model for elliptical galaxies, has been considered under two extreme assumptions regarding the binding energy-mass-radius relations. Unless the binding energy at the time of wind commencement, for a given galactic mass, was a factor of

Ram pressure stripping in a viscous intracluster medium [PDF]

, 2008
In the recent literature there is circumstantial evidence that the viscosity of the intracluster medium may not be too far from the Spitzer value. In this letter, we present two-dimensional hydrodynamical simulations of ram pressure stripping of disc ...

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]

, 2014
X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

Chemical and Thermal History of the Intracluster Medium [PDF]

arXiv, 2004
Clusters of galaxies can be seen as giant astrophysical laboratories enclosing matter in a large enough volume, so that the matter composition can be taken as representing the composition of our Universe.

A dynamical model for the heavily ram pressure stripped Virgo spiral galaxy NGC 4522 [PDF]

, 2006
A dynamical model including ram pressure stripping is applied to the strongly HI deficient Virgo spiral galaxy NGC 4522. A carefully chosen model snapshot is compared with existing VLA HI observations.

Seroprevalence of and Associated Risk Factors for Bovine Viral Diarrhea in Dairy Cattle in and Around Nekemte Town, East Wallaga, Oromiya Regional State, Ethiopia. [PDF]

Biomed Res Int
Bovine viral diarrhea virus (BVDV) is an important pathogen affecting dairy cattle all over the world by causing significant economic losses due to reproductive and respiratory problems, immunosuppressive effects, increased risk of morbidity, and calf mortality.

The Intracluster Medium in z > 1 Galaxy Clusters [PDF]

, 2000
The Chandra X-ray Observatory was used to obtain a 190 ks image of three high redshift galaxy clusters in one observation. The results of our analysis of these data are reported for the two z > 1 clusters in this Lynx field, including the most distant ...

Two-Temperature Intracluster Medium in Merging Clusters of Galaxies [PDF]

, 1999
We investigate the evolution of intracluster medium during a cluster merger, explicitly considering the relaxation process between the ions and electrons by N-body and hydrodynamical simulations.
