Are there black holes at the center of these spiral galaxies?

There's one at the centre of ours. I don't know how common they are, though.

A supermassive black hole is the largest type of black hole in a galaxy, on the order of hundreds of thousands to billions of solar masses. Most, if not all galaxies, including the Milky Way,[2] are believed to contain supermassive black holes at their centers.

They are quite common. Most Galaxies (~80%) that we've looked at have detectable black holes at their centres. The black holes in colliding galaxies will eventually attract each other and become a super massive black hole. That will in turn promote the next galactic collision with it's neighbour, or a passing galaxy.
