End of Moore?s Law ? How long will EUV Lithography last?

Moore’s Law was and still is the driver of innovations in many different areas, including the smartphone, artificial intelligence and autonomous driving. Achieving greater performance while lowering costs and energy consumption has required geometrical shrink powered by the resolution of optical lithography. Without this innovation, the power consumption of e.g. hyperscale data centers would increase linearly with the amount of data and hinder our data-driven world. The invisible engine that has made this possible for more than fifty years is the optics made by ZEISS. Today's leading-edge systems use light with a wavelength of 13.5 nm called Extreme Ultraviolet (EUV) Lithography. The talk will highlight the technological and managerial challenges that had to be overcome to achieve this at ZEISS in Oberkochen. And, looking ahead to the future, the talk will also address how much longer Moore’s Law will last.

The Galactic Halo Renaissance

We are currently witnessing a golden age in Galactic halo science. Largely thanks to the Gaia mission, we now have phase-space plus chemical information for significant numbers of halo stars, globular clusters and satellite dwarf galaxies in the Milky Way. These halo populations can be used to uncover the assembly history of the Galaxy, probe the nature of dark matter, and scrutinise cosmological models. In this talk I will describe recent efforts to address these fundamental questions using a combination of new observational data and state-of-the-art cosmological simulations. In particular, I will discuss the total mass and mass profile of the Milky Way, the last major accretion event that shaped the Galaxy's history, and the (surviving and destroyed) dwarf satellite luminosity function.
