Cosmological Neutrinos
Cosmology has entered a precision era, allowing to make inferences of the constituency of the Universe to the sub-percent level on quantities like the density of matter. The density of light, relativistic components like neutrinos can also be inferred, so that limits on the mass of the neutrinos are an order of magnitude stronger from cosmology than the laboratory, albeit with some important caveats. The neutrino sector could hold some surprises, including dark/sterile species that may constitute the dark matter. An unexplained line in X-ray astronomy may indicate a signal of this sort of dark matter, which has initiated several follow-up astronomical and laboratory searches.
Figure above: Neutrinos are the second most abundant known particle in the Universe. A special, sterile, neutrino could be the dark matter and may be seen in X-ray observations.
The Colloquium is a unique opportunity for students to learn about new developments in physics and what physicists do after they graduate. Hosted by the Department of Physics and Astronomy at California State University Long Beach, the weekly meetings invite guests from universities, research laboratories, and industry to present and discuss current topics in physics. All students are encouraged to attend for a well-rounded experience and training in physics.
