New observational tests of the LCDM (with pesky baryons) paradigm
I will presents new observational tests of the LCDM paradigm. In particular I will focus on the following questions: are there universal dark matter profiles? is there dark matter substructure? Where do galaxy sizes come from? What is the equation of state of dark energy? I will discuss the results underlying the crucial need to uderstand the interplay between baryons and dark matter as part of the paradigm.
