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!

End of the week wrap-up, which discusses how early dark energy runs into trouble when confronted against large-scale structure full-shape galaxy power spectrum data (with a social injustice metaphor related to bad practices when trying to solve the H0 tension), the puzzling origin of GW190814, and a good ambulance chasing paper which turns XENON1T into a machine to set precise constraints on non-standard neutrino interactions.

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!
