Formation of galaxies in simulations andthe low-angular-momentum problem:●●●In first simulations, most of the gas lost angularmomentum when accretedBig bulgesSolution? Heating? ---> UV bckgrnd + stllr fdbck● SPH cause sporious loose of A.M !!●●Resolution related problem ---> zoom in ^^'Not possible in big simulations... so... would it reproducevariety of galaxies and constrained observables?● SPH also creates 'blobs' =/
