Black hole analogues in two-dimensional flows with constant shear
Alessia Biondi, Scott Robertson, Germain Rousseaux
We review the Analogue Gravity description of a unidirectional water wave system, assuming no prior knowledge of General Relativity or differential geometry. In so doing, we genera…

Mathematical and numerical study of a model for navigation in stratified waters
Zeina Rammal, Matthieu Brachet, Germain Rousseaux +1
We derive a linear model of navigation in a two-layer fluid with a variable velocity of the ship. A spectral version of the model including a Rayleigh damping term is analyzed. We…
