Purging the Past: The Current State of Lustration Laws in the Former Communist Bloc
Lustration laws are used in the nations of the former communist bloc to determine whether suspected individuals collaborated with the former state security service. An overview is presented of the current status of such laws
Cosmic Dawn: Studies of the Earliest Galaxies and Their Role in Cosmic Reionization
I review recent progress and challenges in studies of the earliest galaxies,
seen when the Universe was less than 1 billion years old. Can they be used as
reliable tracers of the physics of cosmic reionization thereby complementing
other, more direct, probes of the evolving neutrality of the intergalactic
medium? Were star-forming galaxies the primary agent in the reionization
process and what are the future prospects for identifying the earliest systems
devoid of chemical enrichment? Ambitious future facilities are under
construction for exploring galaxies and the intergalactic medium in the
redshift range 6 to 20, corresponding to what we now consider the heart of the
reionization era. I review what we can infer about this period from current
observations and in the near-future with existing facilities, and conclude with
a list of key issues where future work is required.Comment: Proceedings of the 26th Solvay Conference on Physics: "Astrophysics
