Lecturer: Dr. Noam Libeskind Affiliation: Leibniz-Institut für Astrophysik Potsdam Abstract: Dwarf galaxies are the smallest yet most abundant cosmological objects in existence. Yet owing to their low luminosity, they can only be seen in the immediate neighborhood of the Milky Way, a region known as the Local Group. Observations of these galaxies can help us understand key aspects of the Local Group including the nature of dark matter, our place in the cosmos, and how our specific corner of the universe is embedded in the large scale structure that surrounds us. Most of these

"Global structure of the multiverse and the measure problem": Cosmic inflation is generically a never ending process, with new "bubble universes" constantly being formed. I will discuss the origin of this "multiverse" worldview, its possible observational tests, and one of its major unresolved problems -- the so-called "measure problem".
