It’s time to announce yet another new paper at the Open Journal of Astrophysics Open Journal of Astrophysics. This was published last week (on 15th February 2023) but there was a slight delay in getting the DOI activated and all the metadata registered so I waited until that was done before announcing the paper here.
The latest paper is the 8th paper in Volume 6 (2023) as well as the 73rd in all. This one is another one for the folder marked Cosmology and Nongalactic Astrophysics. The title is “The N5K Challenge: Non-Limber Integration for LSST Cosmology”. The paper is about ways of avoiding using the ubiquitous Limber Approximation which, I discovered this morning, is now 70 years old, Nelson Limber’s original paper on the subject having been published in January 1953.
The lead author of the paper is Danielle Leonard of Newcastle University and there are ten co-authors from around the world in countries including UK, USA, Brazil, Germany, Spain, Switzerland and France on behalf of the LSST Dark Energy Science Collaboration.
