My thoughts on what the Hubble tension really is, based on George Efstathiou’s “To H0 or not to H0?“, arXiv:2103.08723.
After a much needed 3-week break in Spain and 2 weeks “at” the Cosmology from Home conference (great talks, great format, great work by the organizers, 5+ stars from my side), the weekly arXiv synopses return! This week I cover the first constraints on small-scale non-Gaussianity from the UV galaxy luminosity function, astrophysical signatures of black holes carrying magnetic charge, and the HMCODE-2020 code for modelling the non-linear matter power spectrum. Enjoy!
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!
