Public Lecture | Dark Matter: Detecting Gravity’s Hidden Hand
Δημοσιεύτηκε στις 2 Δεκ 2016
Dark
matter is one of the most mysterious components of the universe. Yet it
makes up 23 percent of the mass of the universe – six times the mass of
ordinary, atomic matter. Physicists have never observed dark matter
particles directly, but we see their influence throughout astronomy. The
gravitational pull of this hidden matter is the force that created
structure in the universe, shaping galaxies and forming the distribution
of clusters and voids we see in the sky. One of today’s great
challenges in physics is to observe individual dark matter particles
coming in from the galaxy and striking particles on Earth. This talk
presents the evidence for dark matter and introduces one of the most
ambitious efforts to discover interactions of dark matter particles,
using tons of cryogenic liquid in a deep underground laboratory.
About the Speaker:
SLAC
Professor Tom Shutt has been searching for dark matter particles for
most of his career. He received his PhD from UC Berkeley in 1993. In his
graduate work there, he played a key role in developing low-temperature
germanium detectors for dark matter searches. After terms as a research
fellow at Berkeley and as an assistant professor at Princeton
University, Shutt joined the faculty at Case Western Reserve University
in 2005. At Case, he developed techniques for dark matter searches using
detectors based on liquid xenon. He was co-founder of the LUX
experiment, which is among the current world leaders in the search for
the type of proposed dark matter particles called Weakly Interacting
Massive Particles, or WIMPs. In 2014, Shutt and his collaborator Dan
Akerib moved to SLAC to develop the truly large-scale liquid xenon WIMP
detector LUX-ZEPLIN, or LZ.
