Public Lecture—Deep Science: Mining for Dark Matter

Lecture Date: Tuesday, September 27, 2011. Astronomers infer that the universe contains huge amounts of a mysterious, invisible substance called “dark matter.” To account for the structure of galaxies and clusters of galaxies, the universe must contain six times more dark matter than ordinary atomic matter. We do not know what this stuff is made of. It should be composed of particles of some kind, and, if so, we should be able to see those particles streaming in from space. However, the particles must be very weakly interacting, so exotic methods are needed to make them visible. In this lecture, Sunil presents the evidence for dark matter and describes some of the technologies being used to search for dark matter particles. Among these, Sunil presents his own search experiment, one of the world’s most sensitive, which uses ultra-pure crystals maintained at cryogenic temperatures in a deep underground laboratory.

Lecturer: Sunil Golwala, Caltech

Public Lecture—The Dark Side of the Universe

Lecture Date: Tuesday, August 28, 2007. One of the greatest accomplishments in recent astrophysics is the creation of a model for the complete inventory of the Universe. All the observational data tells us with extremely high certainty that ordinary matter (every particle ever detected by every person who ever lived) makes up only one fifth of all the matter there is. The rest goes by the popular name of dark matter. Because it is dark, dark matter has been notoriously hard to detect; it doesn’t emit or reflect radiation such as light or heat, and it can have only the feeblest of interactions with itself and ordinary matter. So how do we know it is there? In this talk, I will discuss how astronomers observe the invisible matter in one of the true gems on the sky: a giant cluster of galaxies.

Lecturer: Marusa Bradac, SLAC National Accelerator Laboratory.

Public Lecture—Dark Energy. What the …?

Lecture Date: Tuesday, October 30, 2007. What is the Universe made of? This question has been asked as long as humans have been questioning, and astronomers and physicists are finally converging on an answer. The picture which has emerged from numerous complementary observations over the past decade is a surprising one: most of the matter in the Universe isn’t visible, and most of the Universe isn’t even made of matter. In this talk, I will explain what the rest of this stuff, known as “Dark Energy” is, how it is related to the so-called “Dark Matter”, how it impacts the evolution of the Universe, and how we can study the dark universe using observations of light from current and future telescopes. Lecturer: Risa Wechsler, SLAC National Accelerator Laboratory.
