The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Environmental Effects on the Metal Enrichment of Low Mass Galaxies in Nearby Clusters
Environmental Effects the Metal Enrichment Low Mass Galaxies Nearby Clusters
2012/2/21
In this paper we study the chemical history of low-mass star-forming (SF) galaxies in the local Universe clusters Coma, A1367, A779, and A634. The aim of this work is to search for the imprint of the ...
Evolution and Distribution of Magnetic Fields from AGNs in Galaxy Clusters II. The Effects of Cluster Size and Dynamical State
Galaxy Clusters Effects Cluster Size Dynamical State
2011/10/9
Theory and simulations suggest that magnetic fields from radio jets and lobes powered by their central super massive black holes can be an important source of magnetic fields in the galaxy clusters. T...
The effects of X-ray absorption variability in NGC 4395
galaxies: active – galaxies: individual: NGC 4395 – X-rays: galaxies
2011/10/8
We present a new X-ray analysis of the dwarf Seyfert galaxy NGC 4395, based on two archival XMM-Newton and Suzaku observations. This source is well known for a series of remarkable properties: one of ...
Theoretical Spectra of the Am CVn Binary System SDSS J0926+3624 : Effects of Irradiation onto the Donor Stars
Theoretical Spectra Binary System Effects Irradiation Donor Stars
2011/9/29
Taking into account a range of parameters determined from the evolutionary models and available observational data, the detailed non-LTE spectra for the primary star and the irradiated donor star in t...
Cross-helicity effects and turbulent transport in magnetohydrodynamic flow
Cross-helicity effects turbulent transport magnetohydrodynamic
2011/9/28
In the presence of large-scale vortical motions and/or magnetic-field strains, the turbulent cross helicity (velocity--magnetic-field correlation in fluctuations) may contribute to the turbulent elect...
The UV Upturn in Elliptical galaxies and Environmental Effects
Elliptical galaxies Environmental Effects
2011/9/26
It is suspected that the ultraviolet (UV) upturn phenomenon in elliptical galaxies and extended horizontal-branch stars in globular clusters have a common origin. An extremely high abundance of helium...

On the Relativistic Beaming and Orientation Effects in Core-Dominated Quasars
active jets quasars
2009/5/19
In this paper, we investigate the relativistic beaming effects
in a well-defined sample of core-dominated quasars using the correlation
between the relative prominence of the core with respect to th...
Effects of the Size of Cosmological N-body Simulations on Physical Quantities– II：Halo Formation and Destruction Rate
Large scale structure of Universe N-body simulations galaxies
2009/5/12
In this study we show how errors due to finite box size
affect formation and the destruction rate for haloes in cosmological N-body
simulations. In an earlier study we gave an analytic prescription ...

2009/5/7
This paper describes the space weather effects of a major CME which was accompanied by extremely violent events on the Sun. The signatures of the event in the interplanetary medium (IPM) sensed by Oot...
Transient Perturbations and their Effects in the Heliosphere, the Geomagnetosphere, and the Earth’s Atmosphere：Space Weather Perspective
Space weather geomagnetic storm cosmic ray Forbush decrease interplanetary shock coronal mass ejection
2009/5/7
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth™s atmosphere. In particular, transient perturbations in solar win...
