This is the astro-ph blog of the Theoretical Modelling of Cosmic Structures group (TMoX) at the Max-Planck-Institute for Extraterrestrial Physics. We are an independent Max-Planck Research Group focusing on the various aspects in the formation and evolution of galaxies. Part of our focus is on the formation and evolution of early-type galaxies, super-massive black holes, the formation of the first structures in the universe and the enrichment history of the Universe. We are theoreticians using analytic modelling as well as numerical simulations in our work.
The CosmologyCake blog is dedicated to the discussion of research papers and current developments. We will regularly post interesting papers and comment on them. Feel free to leave your comments as well. We encourage authors of discussed papers to post replies if they wish to. Our aim is to provide a platform to discuss recent astro-ph papers within a wider audience. Please feel free to send papers you would like to be discussed to us at firstname.lastname@example.org.

Disruption of a Proto-Planetary Disk by the Black Hole at the Milky Way Center
This (link) is a very interesting paper trying to explain the properties of the gas cloud close to Sgr A* using back of the envelope calculations. Though the model will not be the final word in the study of this gas cloud, it provides interesting prediction, especially on its density evolution, without the use of any numerical simulations. It will be interesting to see how it will hold up with respect to detailed numerical simulations that are underway or already run (e.g. http://arxiv.org/abs/1201.1414B)
