M.Raveri:Measuring the speed of GW

[Maxim Khlopov]

On 26.09.2014 M.Raveri gave a VIA talk "Measuring the speed of GW".
It's record is in VIA Library:

The following questions and comments were put in Discussion:
Shantanu: There is also one more method proposed and carried out by Sergei Kopeikin(who sometimes attends this forum) using Shapiro delay of moving object. This was in 2003

Houri Ziaeepour: You said that the effect of GW speed is not degenerate with other parameters. But if DE is due to modified GR there must be a relation with expansion rate, etc.

Shantanu: let me ask a naive question. Can the speed of gravitational waves found from such measurements be used a null test? In other words how would the signal look like if you got a speed of gravitational waves= infinity

Houri Ziaeepour: Thanks. I gave the expansion rate as an example. Another degenerate parameter would be equation of state of DE.
