Vidi Grant for Daniel Baumann.
Baumann was awarded a Vidi grant by the Netherlands Organisation for Scientific Research (NWO) to study “The Origin of Structure in the Universe”. All structure in our universe is formed by the gravitational collapse of fluctuations in primordial matter, but the physical origin of these fluctuations remains mysterious. He will for example explore the possibility that quantum effects in the early universe were the source of all structures.

Marie Curie Fellowship for Gui Leite Pimentel.
Pimentel received a Marie Skłodowska-Curie Individual Fellowship for his project entitled “Microscopic Probes of Inflationary Cosmology”. To understand the origin of inflation, he will identify new particles that could have been produced during this period of inflation and try to determine whether these particles can have stopped the accelerated expansion.

ERC Consolidator Grant for Ben Freivogel.
Freivogel’s ERC project intends to accurately identify the circumstances and scales where quantum-mechanical effects of gravity become relevant.  Although these quantum effects are typically believed to be extremely tiny on scales that can be probed experimentally, recent results of Freivogel and others suggest that under certain circumstances quantum gravity effects can become large and perhaps even observable on much larger, macroscopic, length scales.  This could in particular have major consequences for the possibility to probe quantum gravity through cosmology.
