Based on the star formation histories of galaxies in halos with different masses, we develop an empirical model to grow galaxies in dark matter halos. This mode
An analytical solution to the three-dimensional telegraph equation is presented.This equation has recently received some attention but so far the treatment has
We aim to numerically study evolution of Alfv′en waves that accompany short-lasting swirl events in a solar magnetic flux-tube that can be a simple model of a
We study the motion of G-band bright points(GBPs)in the quiet Sun to obtain the characteristics of different motion types.A high resolution image sequence taken
