Open clusters in 2MASS photometry - I. Structural and basic astrophysical parameters
associations general – infrared galaxies – astronomical databases
2011/10/21
The main goal of our project is to obtain a complete picture of individual open clusters from homogeneous data and then search for correlations between their astrophysical parameters. The near-infrare...
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...
