Title: Galactic extremophiles: the most massive galaxies of the Universe

Abstract: If one thinks about galaxies as the entities that constitute a larger system (our Universe) some of them stand out because of their exceptional characteristics. In particular, the most massive galaxies of the Universe are already in place very early on (12-13 Gyr) and as such they are privileged laboratories to investigate accelerated galaxy evolution. Adding to this fact the huge transformations they undergo across cosmic time, namely their morphological change (from vigorous star forming disks to passive "red & dead" spheroids), their dramatic size evolution (3-5x smaller at high-z), their scarcity and the large overdense environments they inhabit, we have created the perfect cocktail for a better understanding of extragalactic Physics. I will therefore review why galaxy weirdos could change our conceptions about the Universe we live in.
