Einstein Shift and Doppler Shift

  title={Einstein Shift and Doppler Shift},
  author={Arthur Stanley Sir Eddington},
IN answer to Sir Oliver Lodge's question (NATURE, December 26, p. 938), it depends on our point of view whether the Einstein shift is considered to be imposed on the light at its origin or in course of transit to us. We cannot state the frequency of the ether vibrations without presupposing a system of time-reckoning, and in the non-Euclidean region round the gravitating star the ordinary conventions of time-reckoning have broken down. There is a particular system of time-reckoning (t) commonly… Expand
Tracing black hole and galaxy co-evolution in the Romulus simulations
We study the link between supermassive black hole growth and the stellar mass assembly of their host galaxies in the state-of-the-art Romulus suite of simulations. The cosmological simulationsExpand
