The XENON research project uses a dual phase time projection chamber to search for this component, whose distribution is plotted on a NavarroFrenkWhite profile.
The XENON research project uses a dual phase time projection chamber to search for this component, whose distribution is plotted on a NavarroFrenkWhite profile. The cusp-core problem has led to the suggestion that this component is self-interacting. Plots of orbital velocities of bodies against radial distance on a galactic rotation curve lead to the inference of this component, which (*) Fritz Zwicky postulated after studying the Coma Cluster. Mordehai Milgrom developed MOND, or Modified Newtonian Dynamics, as an alternative to this entity. Axions are candidates for its "cold" form, while its "hot," ultra-relativistic form would be contributed from neutrinos. For 10 points, name this currently undetected hypothetical substance that might comprise most of the mass of the universe.
