Physics, Astronomy & Cosmology / Is the frequency of gravitational waves affected by Special Relativity?
« on: 18/10/2017 20:35:27 »
In the region of two merging black holes or neutron stars, Special Relativity predicts that events should appear to be slowed down, as viewed by a distant observer (us). This is due to:
- The objects are in a deep gravitational well
- They are moving very quickly just before they merge (a large fraction of the speed of light)
Several of the recent gravitational wave events have had final frequencies of 400-500Hz.
How much would this have been "red shifted" by the time dilation inherent in escaping from this deep gravitational "hole"?
