My thoughts on what the Hubble tension really is, based on George Efstathiou’s “To H0 or not to H0?“, arXiv:2103.08723.
About two weeks ago, my (first) daughter was born. Needless to say this has been a great moment of joy for us! I will be taking an extended period of parental leave (which will then seamlessly merge into my summer holidays), with the exception of the period July 5-July 16, where I’ll be attending, at least part-time, Cosmology from Home 2021 (too good to miss, given how amazing the 2020 edition was!).
A quick note to inform regular readers that I’ll have to disappear for a while due to a confluence of several time-draining commitments including a proposal for a fellowship application I have to submit soon, and preparing for an interview for a faculty position for which I’m shortlisted (this is the position I applied for mentioned in this earlier busy note), as well as some personal issues. I’ll have to cancel this week’s post and probably next week’s one as well. Hopefully “see” you soon!
Yesterday I found out, to my great delight that a proposal for a medium-small grant I applied to from the Blanceflor Foundation has received funding! (so now you know what this “proposal” mentioned in my earlier busy note was about - the “application” mentioned is still pending)
This week’s post is devoted to the search of Jupiter’s lightning bolts (aka gamma-rays from dark matter), the construction of new astrophysically-motivated black hole mass function and subsequent search for the black hole mass gap, and a (unusual for this blog, I know!) philosophical discussion on the anthropic principle.

After being “away” a few weeks where I used this blog as a conference diary (see TMCC2021 and A (Hubble) Tension Headache), the usual arXiv posts return, covering primordial black holes as (not) dark matter, difficulties in constructing working and realistic early dark energy models, and biases to parameter constraints from the effect of baryonic feedback on the gravitational lensing of the CMB. Enjoy the read!
