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!
Top arXiv papers from Week 17, 2020
With a week of delay due to Italian bureaucracy-induced commitments, my Week 17 summaries are now out. There is a new entry in terms of topics covered, i.e. the thorny issue of naturalness in particle physics and cosmology (besides two papers covering limits on the duration of inflation, and independent inferences of the baryon energy density from Planck). As always, comments are very welcome!
