I may be away at a conference, but it’s still time to announce yet another new paper at the Open Journal of Astrophysics. This one was published on Monday 19th June.

The latest paper is the 20th  so far in Volume 6 (2023) and the 85th in all,  so with still more than half of 2023 remaining and many papers still in the pipeline, we’re on track to reach a total of 100 papers by the end of 2023!

The primary classification for this paper is Cosmology and Nongalactic Astrophysics and its title is “Sparse Bayesian mass-mapping using trans-dimensional MCMC”.  The paper describes a new trans-dimensional Markov Chain Monte Carlo sampler for mass-mapping, using wavelets, for the construction of mass maps from weak gravitational lensing which, as I’ve previously mentioned on this blog, is what the cool kids do these days.

The authors are: Augustin Marignier, Thomas D. Kitching & Jason D. McEwen (MSSL, Mullard Space Science Laboratory), Ana M. G. Ferreira (Department of Earth Sciences), all at University College London.

Time to announce yet another publication in the Open Journal of Astrophysics. This one was published yesterday, actually, but I didn’t get time to post about it until just now. It is the 16th paper in Volume 4 (2021) and the 47th in all.

The latest publication is entitled MCMC generation of cosmological fields far beyond Gaussianity and is written by Joey Braspenning and Elena Sellentin, both of Leiden University.
