How do Antishock Bodies / Cuchemann Carrots delay shock-induced flow separation?

Question

There are several online resources that describe these aerodynamic devices as either "Antishock Bodies" or "Kuchemann Carrots" and that they are used to produce some combination of the following effects:

1. Delay shock-induced flow separation
2. Contribute to the Area-Rule concept
3. Both of the above (source-dependent)

I cannot find any reading about how these devices perform the task of delaying shock induced flow separation. I am interested in how exactly these bodies interact with the combination of supersonic and subsonic flow across the chord line of a transonic wing in order to delay shock-induced flow separation to some higher Mach number than would be possible without them installed.
