SC 213 – Dark Matter in the Universe: Class presentation available

DARK MATTER 2

Dark matter tends to clump into the center of the galaxy, forming a
dense “cusp”. That is where most of the annihilations should happen.

Dark matter has been known to be the gravitationally dominant component of matter in the universe since the 1930s. It dominates the formation of galaxies and large scale structure of the universe and is detectable in the structure in the cosmic microwave background radiation.   Professor Abazajian discussed the preponderance of evidence for dark matter as well as current efforts in determining what it is from astrophysics and cosmological studies.

Professor Tait described the search for the mysterious dark matter that makes up the bulk of the mass of the Universe.  While we can infer dark matter’s existence through the gravity it creates, understanding its identity and where it fits into a model of particle physics requires that we observe its interactions with ordinary matter.  Experiments such as the Large Hadron Collider in GenevaSwitzerland offer a unique opportunity to search for dark matter, and may hold the key to its nature.

Presenters: 

Kevork Abazajian, Ph.D., is an Astronomer in the UC Irvine Dept. of Physics and Astronomy studying dark matter, dark energy, and cosmology.

Tim Tait, Ph.D., is a Particle Physics Theorist in the UC Irvine Dept. of Physics and Astronomy working on the theory for detecting dark matter at the LHC, in satellites, and in underground experiments.
