When galaxies collide, what happens in general to the stars contained within them?

    They mostly pass by the stars in the other galaxy without colliding.
     They merge into one galaxy, leaving the other one relatively underpopulated.
     They collide head-on with stars in the other galaxy, forming larger stars.
     They are captured in large numbers within the supermassive black holes at the centers of each galaxy.
     They get dimmer due to obscuration by gas and dust in the other galaxy.
