My thoughts on what the Hubble tension really is, based on George Efstathiou’s “To H0 or not to H0?“, arXiv:2103.08723.
In this week’s summaries I look at vector-tensor Horndeski gravity (the lesser known sibling of scalar-tensor Horndeski gravity), the (im)possibility of solving the Hubble tension with late-time transitions in the dark energy, and a reconstruction of the time-dependent interaction between cold dark matter and vacuum energy. Note the possibility that next week’s entry might be cancelled or in the best case delayed (see my away note).
On the day the UK leaves the EU and I get to live in a non-EU country again after 5 years (yeah!), here comes the fifth installment of my “Top arXiv papers of the week“ column. From this week, I will be reviewing 3 papers instead of 5 (for more info, please see this post). You might also have noticed that my blog now has a name (again, see this post for more info). Enjoy!
