This week’s entry covers the exciting ACT data release, the mutual tension between ACT, Planck, and SPT, and a flexible parametrization of black hole shadows based on a class of curves known as limaçons. Have a nice weekend!

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!
