New Hubble Data explains the indicated missing Dark Matter
Dark Matter: Understood as the key constituent in the current models of galaxy formation and evolution, has been elusive enough to not explain its “absence” in the distant galaxies of NGC 1052- DF2 and NGC 1052-DF4. However, New Data obtained from the Hubble Telescope, in coordination with its analysis employing “Deep Optical Imaging” have indicated otherwise.
Extensive Research undertaken by Mireia Montes and her team at the University of New South Wales, Australia has discovered that the missing dark matter can be explained eloquently via the effects of “Galactic Tidal Disruption”. Mutually interacting galaxies, NGC 1035 and NGC 1052-DF4 are tearing each other apart via strong gravitational interaction and in this process, dark matter is removed, while the stars embedded feel the effects of the interaction with another galaxy at a later stage.
An intensive analysis of the “Galaxy’s Light” and the “Galaxy’s Distribution of Global Clusters” have further led to the rectification of this anomaly. Aiding the Hubble Telescope were the Gran Telescopio Canarias and the IAC80 Telescope.
The crucial discovery of the mechanism to support the missing dark matter via tidal disruption has not only solved an astronomical conundrum but has also brought a much-needed relief. For otherwise; The Laws of Gravity themselves would have to be changed in order to explain the anomalies and fit them in!
