The Puzzling Dumb-Bell Galaxy Ndc 4782/3: Galactic Wakes Versus Bent Jets
Abstract
Galactic wakes and bent radio jets are the only means to disclose the motion of galaxies on the sky: in combination with the X-ray and optical properties of their surroundings they provide accurate measurements of the cluster's gravitational potential, and its dynamical state. It is therefore very alarming when one finds a system in which the wakes and bent jets disagree. We propose to study this puzzling system: the dumb-bell galaxy NGC 4782/3. The Chandra observation will enable us to disclose the fine structure and spectral properties of the small-scale wakes and compare them with our simulations. We will also be able to assess the bending mechanisms for the radio jets, and finally establish the universality of one (or both) methods in unveiling the motion of galaxies.
