WebStar formation lies at the very center of the baryon cycle and plays a pivotal role in shaping galactic ecosystems. There are di erent measures of this process, all of which help to under-stand and characterize its behavior through cosmic history. One example is the star-formation rate (SFR), as it provides a quanti- WebThe cosmic star formation history directly determines a wide range of key observables of the Universe. Making use of the computational simplification provided by the analytic fit for the star formation density derived above, we can conveniently obtain a number of such predictions. Clearly, this application is one of the main reasons why an ...
