MEGARA allows to obtain deep 2D spectroscopy of extended objects.
M32 is the nearest (compact) elliptical and a companion of the Andromeda galaxy. It is now believed to be the remnant of a more massive system stripped of its stars.
The 2D kinematics of M32 are key to understand the effects of interactions on the formation of dwardfs, ellipticals, lenticular and to confirm M32’s true nature.
The results: Distortions (non asymmetry) of the sigma and h4 maps are testimony of a major interaction with Andromeda.
