- Dark Matter Annihilation
- Dark matter particles could be their own antimatter partners. Therefore, annihilation could occur if two dark matter particles collide.
- Haslam Map and WMAP
- The Haslam Map measures synchrotron radiation at a radio frequency.
- Lux Detector
- Rick Gaitskell of Brown University is one member of a team of scientists and researchers attempting to strike particle physics gold.
- Lux Detector PMTs
- The nucleus recoils and emits scintillation light which we detect using photosensitive detectors at the boundaries of the container.
- Lux Detector Water Shield
- This multilayered strategy of putting the detector below ground and immersing it in water allows for an extremely low background event rate in their detector.
- Particle Annihilation
- Annihilation is what happens when a particle meets its antimatter partner.
- Synchrotron Radiation
- Synchrotron Radiation is generated as charged particles, that are moving near the speed of light, spiral around the lines of a magnetic field.
- WIMP Interaction with Xenon
- When a WIMP interacts with the xenon, it not only causes an initial burst of light, but it also ionizes the xenon atoms.
- Axion Dark Matter Experiment
- If dark matter consists of axions, the ADMX experiment might detect them within a decade.
- Bullet Cluster
- Contrasting x-ray and light images of the Bullet Cluster reveal strong evidence for the existence of dark matter.
- Coma Cluster
- The Coma cluster which provided the first evidence that dark matter exists.
- DAMA/LIBRA Project
- A technician works on detectors for the DAMA/LIBRA project, which stimulated the theory of dark forces.
- Dark Matter Simulation
- The distribution of dark matter in the universe.
- Fermilab's Search for Axions
- Axion hunters: two Fermilab physicists with their experiment designed to detect axions.
- Galaxy Cluster
- Clusters of galaxies contain significantly more dark matter than visible matter.
- MACHO Project
- This Australian telescope unsuccessfully sought evidence for the existence of MACHOs based on their putative effect on starlight.
- Peebles and Ostriker
- James Peebles (left) and Jeremiah Ostriker (right) found evidence for dark matter in their computer simulations.
- Rubin, Vera
- In the 1970s Vera Cooper Rubin and Kent Ford made observations of galaxies that led them to infer that the galaxies must contain dark matter.
- Zwicky, Fritz
- Fritz Zwicky suggested the existence of dark matter, and also predicted the transition of ordinary stars into neutron stars and that galaxies could act as gravitational lenses.
