My thoughts on what the Hubble tension really is, based on George Efstathiou’s “To H0 or not to H0?“, arXiv:2103.08723.
The common denominator between the 3 papers I selected this week is that they all are, to some extent, provocative, although related to completely different topics (respectively the Hubble tension, possible hints for dark matter in low-threshold direct detection experiments, and the possible need to move beyond archaic units in cosmology). I won’t say anything more to not spoil the fun, so enjoy reading!
This post is meant to advertise both my book review which just appeared in Nature Astronomy, as well as the book I reviewed. Two months ago Nature Astronomy asked me to write a book review on The Cosmic Revolutionary’s Handbook, a new popular science book by Luke A. Barnes and Geraint F. Lewis to be published by Cambridge University Press (one of the oldest and most prestigious publishing houses in the world) in March.
This is the first entry of my “Top arXiv papers of the week” column. As explained in my welcome post, I plan to update this column at the end of each week with a brief description of the 5 papers which I found most interesting among all those posted on the arXiv during the week.
