  1. Aug 20,  · The idea of dark matter is very well motivated by other observations. Completely independent cosmological and astrophysical phenomena that aren’t explained within other Author: Ethan Siegel.
  2. Apr 04,  · The angular size of this ring can be calculated with some geometry: where G is the gravitational constant, M is the mass of the galaxy, c is the speed of light, and d LS, d L, and d S are the angular diameter distances between the galaxy and the quasar, the galaxy and us, and the quasar and us, respectively. We can measure these distances using redshifts.
  3. Dec 28,  · A Deficit of Dark Matter in Elliptical Galaxies The 'missing mass problem' is a long-standing issue in astrophysics, being present in galaxies, cluster of galaxies and even at the cosmological scale. Astronomers from Taiwan have used archival data from PN.S and SAURON to study the internal dynamics of seven nearby elliptical galaxies, and.
  4. As a result, there are some researchers who do not believe that dark matter exists and have proposed alternative explanations for the strange behaviour of galaxies. Spectacular success. Now a new analysis suggests that one alternative theory called MOND describes the properties of two elliptical galaxies just as well as dark matter.
  5. Sep 19,  · The kinematics of the outer parts of three intermediate-luminosity elliptical galaxies were studied with the Planetary Nebula Spectrograph. The galaxies' velocity-dispersion profiles were found to decline with the radius, and dynamical modeling of the data indicates the presence of little if any dark matter in these galaxies' halos. This unexpected result conflicts with findings in other Cited by:

  7. Evidence for Dark Matter; Evidence for dark matter in spiral galaxies In spiral galaxies like the Milky Way, we derive the gravitational mass from observing the motions of stars and gas clouds in the disk as they orbit the derspaspecatere.piasoftnerdvaxoolicoramnungwritresand.co rotation curve of a galaxy shows how the velocity of stars around the center varies as the distance from the center increases.
  8. Dark matter. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter. Dark matter.
