In the Dark

Time to catch up with a couple of recent publications at the Open Journal of Astrophysics.

The first paper was published on Friday 23rd June. It is the 21st in Volume 6 (2023) and the 86th in all.

The primary classification for this paper is Cosmology and Nongalactic Astrophysics and its title is “CosmoPower-JAX: high-dimensional Bayesian inference with differentiable cosmological emulators”. The paper is about a new method, based on machine learning, to construct emulators for cosmological power spectra for the purpose of speeding up inference procedures. The software described in the paper is available here.

The authors are Davide Piras (of the University of Geneva, Switzerland) and Alessio Spurio Mancini (of the Mullard Space Sciences Laboratory, University College, London, UK)

The second paper was published yesterday. It is the 22nd in Volume 6 (2023) and the 87th in all. Although 87 is an unlucky number for Australian cricketers – 13 short of a century – we’re still well on track to reach 100 papers by the end of the year.

Once again the primary classification for this paper is Cosmology and Nongalactic Astrophysics. The title of this one is “The alignment of galaxies at the Baryon Acoustic Oscillation scale” by Dennis van Dompseler, Christos Georgiou & Nora Elisa Chisari all of Utrecht University, in The Netherlands.
