From Light to Dark & back to Light – A brief history At some point after the Big Bang the hot plasma opaque to light had cooled down enough so that during Recombination, electrons and...
Studying the uncharted territories of the Standard Model using gravitational waves
Our current knowledge about the elementary constituents of Nature can be summarized by the Standard Model of Particle Physics. This model aims to describe what the elementary building blocks of the Universe are and how...
