New Publication at the Open Journal of Astrophysics

It’s time once again for me to announce another new paper at the Open Journal of Astrophysics. The new paper, published yesterday, is the 12th paper in Volume 5 (2022) and the 60th in all. The latest publication is entitled “Minkowski Functionals in Joint Galaxy Clustering & Weak Lensing Analyses” and the authors are Nisha Grewal, Joe Zuntz and Tilman Tröster of the Institute for Astronomy in Edinburgh and Alexandra Amon of the Institute of Astronomy in Cambridge. The paper is in the folder marked Cosmology and Non-Galactic Astrophysics.

Incidentally, Dr Alexandra Amon is the winner of this year’s Caroline Herschel Lectureship in Astronomy, so congratulations to her for that too!

The new paper is about the application of topological characteristics known as Minkowski Functionals to cosmological data. This approach has been used in the past to study the pattern cosmic microwave background temperature fluctuations; see e.g. here for one of my forays into this way back in 2008. Now there are more high-quality datasets besides the CMB so there are more opportunities to use this elegant approach. Perhaps I should do a blog post about Minkowski Functionals? Somewhat to my surprise I can’t find anything on that topic in my back catalogue here In The Dark

Anyway, here is a screen grab of the overlay which includes the  abstract:

    I’ve not come across Minkowski functionals and the exposition at Wikipedia is full of the abstract generality that renders it unreadable unless you already know the intuitive idea. Which is what, ie where can I read about it please?

  2. […] I thought I would do a brief post on the subject of Minkowski Functionals, as used in the paper we recently published in the Open Journal of Astrophysics. As as has been pointed out, the Wikipedia page on Minkowski Functionals is somewhat impenetrable […]
