Cosmic parallax
  OKC colloquia

Tuesday 13 May 2014
from 13:15 to 14:15
at Nordita, 122:026
Speaker : Syksy Rasanen (Helsinki)
Abstract : Parallax, the change of the position of objects on the sky with time, was proposed as a cosmological test in 1935. The Gaia satellite, launched in December 2013, will probe parallax on cosmological scales for the first time. I will discuss the theory of cosmic parallax and explain how it can be used to test the FRW metric without any assumptions about the matter content or the gravitational field equation. ct: Kjell Rosquist
