Query: Probing the constancy of the speed of light with future galaxy survey:
  the case of SKA and Euclid   In [1] a new method to measure the speed of light through Baryon Acoustic
Oscillations (BAO) was introduced. Here, we describe in much more detail the
theoretical basis of that method, its implementation, and give some newly
updated results about its application to the forecast data. In particular, we
will show that SKA will be able to detect a 1% variation (if any) in the speed
of light at 3$\sigma$ level. Smaller signals will be hardly detected by
already-planned future galaxy surveys, but we give indications about what
sensitivity requirements should a survey fulfill in order to be successful.
