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.
Ever wanted to estimate some cosmological parameters but your MCMC chains are too slow? Check out today’s paper for a method to speed up your estimation using iterative emulation.
How to find an exoplanet, twice.
Is CoRoT-7d real, or is it stellar activity masquerading as a planet? Haywood et al. build a noise model to analyze CoRoT-7’s activity to find out.
