Motivated by flat space holography, I will argue that massive spin-s fields in Minkowski space near timelike infinity are massive carrollian fields on the carrollian counterpart of anti-de Sitter space called Ti. Its isometries form the Poincaré group. On this space, I will construct the carrollian spin-s fields using the method of induced representations and show their relation to Wigner's UIR of Poincaré. One can furthermore providea a dictionary between massive carrollian fields on Ti and massive fields in Minkowski space.
