Dwarf galaxies gobbled by their giant neighbours

Spiral galaxies are known to grow by swallowing their diminutive neighbours; as this process occurs, the dwarf galaxies become severely distorted.

    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, 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.

    I guess my post was in Swahili.
