This week’s entry is entirely dedicated to dark matter and ways of searching for or constraining its properties which I would define “off the beaten track”, ranging from using the first stars, to black hole shadows, to quantum gravity-inspired theoretical guiding principles. Enjoy!

This week’s entry features a new ACT CMB lensing cross BOSS CMASS galaxies cross-correlation measurement implementing a new tSZ-cleaning procedure, a new update on the H0 tension and in particular how fifth forces could lower the TRGB-calibrated measurement (besides the usual Cepheid-calibrated one), and finally the return of black hole shadows (in asymptotically de Sitter spacetime). Enjoy and stay safe!
