This week’s post covers ultralight axions and galaxy clustering, using heavy elements to probe inelastic dark matter, and constraining primordial black holes from the dynamics of Neptune. Enjoy!
Blanceflor-funded project: Direct Detection of Dark Energy
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)
What is the Hubble tension, really? A SH0ES-centric view of the problem
My thoughts on what the Hubble tension really is, based on George Efstathiou’s “To H0 or not to H0?“, arXiv:2103.08723.

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!

This week’s post is dedicated to dark energy in the context of (not solving) the Hubble tension, the possibility that the NANOGrav pulsar timing array may have detected non-tensorial gravitational wave polarizations, and the construction of a general covariant action for the so-called holographic dark energy model. Enjoy the read and have a nice weekend!
