Description
We perform N-body simulations of a minor merger between a Milky Way like
galaxy and a disk-like satellite. In this set of collisionless runs we
vary critical parameters such as the luminous mass ratio between the two
galaxies (1:6, 1:9), the type of orbit (direct or retrograde) and the
number of particles (185,000, 555,000 and 1,850,000). We estimate the
growth of the disk thickness due to the accretion of satellites by
measuring the median of the vertical distribution of the luminous
material. After correcting our values for numerical heating we find that
the merger increases the scale height by a factor of ~2 in all the
remnants. The global response of the disk to the merger tidal field
dominate the thickening.
