Re-evaluating evidence for Hawking points in the CMB

21 Jan 2020  ·  Jow Dylan L., Scott Douglas ·

We investigate recent claims for a detection of "Hawking points" (positions on the sky with unusually large temperature gradients between rings) in the cosmic microwave background (CMB) temperature maps at the 99.98% confidence level. We find that, after marginalization over the size of the rings, an excess is detected in Planck satellite maps at only an 87% confidence level (i.e., little more than 1$\sigma$)... Therefore, we conclude that there is no statistically significant evidence for the presence of Hawking points in the CMB. read more
