2010/11/11
The jets image modelling of gravitationally lensed sources have been performed. Several basic
models of the lens mass distribution were considered, in particular, a singular isothermal ellip-soid, an...
Modelling the shapes of the largest gravitationally bound objects

We combine the physics of the ellipsoidal collapse model with the excursion set theory to study the shapes of dark matter halos. In particular, we develop an analytic approximation to the nonlinear ev...
