We prove that α is b-normal if and only if it possesses no base-b “hot spot.” In other words, α is b-normal if and only if there is no real number y such that smaller and smaller neighborhoods of y are visited by the successive shifts of the base-b expansion o...

A Hot Spot in Coma

We study the temperature structure of the central part (r ≤ 18≃ 0.7h 50 Mpc) of the Coma cluster of galaxies using ASCA data. Two different analysis methods produce results in good agreement with each other and reveal the presence of interesting structures in the gas temperature distribution. Globally, the average temperature in the center of the cluster is 9.0±0.6 keV in good agreement with pr...
