Twisting of galaxy orientations and the intrinsic alignment of galaxies

Pourvu: 

Oui
The majority of galaxies appear to be elliptical when projected on the sky. Observations have shown that the shapes of these galaxies align with the tidal matter density field within which they are formed. Therefore the observation of the alignment of galaxies may provide information on this underlying tidal matter density field. In this internship the intern will study the relation between isophotal twisting of galaxy images projected on the sky (the change in the galaxies orientation with distance from the galaxy centre) and the orientation of the galaxy in 3D, the deprojected orientation of the galaxy. This could potentially allow us to study in more detail the tidal matter density field.
