Constraining physical parameters in a cosmological survey is often computationally expensive, especially when considering more than one survey at a time. The authors of this paper offer a simple method to reconstruct parameter distributions in a fraction of the time needed for most high-performance computers.
The longstanding role of galaxy mergers as drivers of star-formation is brought into question
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Neighboring exoplanets appear to come in similar sizes. But is this a result of observational bias?
Today’s authors use a new technique to make new discoveries about the Seven Sisters.
Observations of dim galaxies lensed by foreground clusters provides a way of measuring the progression of reionization.
