These peculiar galaxies are like a natural experiment played out
on a
cosmic scale and by cataloguing them, astronomers can better understand the physical processes that warp spiral and elliptical galaxies into new
shapes.
Thus, considering LEO missions such as CHAMP, GRACE, and Formosat3 /
COSMIC, the radio occultation techniques are already well established to monitor the
shape of vertical electron density structure
on global
scale (Jakowski et al. 2011).
