... • Studies of ICL in cosmological simulations require a model of star formation from cold gas, including cooling and feedback effects. Recent studies are by Murante+2004, Willman+2004, SommerLarsen+2005. Here we use Gadget-2 with the two-phase model of Springel & Hernquist (2003). • Current hydrodyna ...

They have allowed determination of the dense core mass spectrum down to substellar masses, and investigation of its relationship to the initial mass function (Motte et al. 1998; Gahm et al. 2002; Hatchell et al. 2005). High-mass star formation is even less well constrained (e.g., Zinnecker & Yorke 2 ...

... A double-convex (DCX) lens is regarded as the best single element for 1:1 imaging because of its symmetrical shape, as both sides of the lens have equal power, instead of one side bending rays more than the other, such as a plano-convex (PCX) lens. Since the lens system is made of just one lens, the ...
