July 23 SLAC public lecture

Debbie Bard, a staff scientist at SLAC in Menlo Park and a member of the Kavli Institute for Particle Astrophyics and Cosmology, will deliver the SLAC Public Lecture, “The Dark Universe Through Einstein’s Lens,”on July 23 from 7:30 to 8;30 pm.

One of the most surprising predictions made by Einstein’s theory of relativity is that light doesn’t travel through the universe in a straight line. The gravitational field of massive objects will deflect the path of light traveling past, giving some very dramatic effects. We see multiple images of quasars, galaxies smeared into arcs and circles and magnified images of the most distant objects in the universe. This talk will explain how gravitational lensing was first observed and discuss how scientists use this phenomenon to study everything from exoplanets to dark matter to the structure of the universe and the mysterious dark energy.

Bard began her career at SLAC as a particle physicist and has since graduated to studying galaxy clusters – moving from exploring the most miniscule bits of matter in the universe to the largest structures known. Currently she’s developing new ways to mine data from the future Large Synoptic Survey Telescope (LSST) for information. Discovering how to push gravitational lensing to its limits is one promising focus of her research.

SLAC Public Lectures are free and last about an hour. Refreshments are served after the lecture, when guests have an opportunity to speak with the presenter. All are welcome, and you need not be a scientist to attend. Public lectures are intended for a general audience. SLAC is located at 2575 Sand Hill Road in Menlo Park.

The colony of honeybees that’s lived in an old blue oak tree in front of Building 41 on the SLAC campus in Menlo Park for nearly 50 years has been relocated because the decaying tree must be cut down, for safety’s sake, prior to the building’s renovation. Beginning in May, San Jose beekeeper Art Hall […]

John Hill watched with eager anticipation as controllers in Menlo Park ramped up the power systems driving SLAC’s X-ray laser in an attempt to achieve the record high energies needed to make his experiment a runaway success. The Brookhaven National Laboratory scientist was the leader of a research team that had come from Illinois, Germany, […]

For the past 15 years, two small, grotesque statues have spent their days squatting on the roof of Building 280B on the SLAC campus in Menlo Park, peering out over the cars in Parking Lot G. No one is quite sure how the two stone gargoyles reached their perches — or if they are, they’re not […]

The new Arrillaga Recreation Center at SLAC in Menlo Park in managed by Chris Spells. We caught up with him behind the reception desk, where he spends much of his day checking in people at the fitness center, tracking equipment orders and gathering suggestions for improvements. Welcome to SLAC. We’re going to let you introduce […]

From 150-year-old native oaks to young redwoods, nearly 6,000 trees grace SLAC’s 426-acre campus in Menlo Park.Most of them are labeled with a three-digit number on a one-inch-diameter aluminum disk nailed into their trunk. These tree tags are an integral part of a comprehensive SLAC’s tree-management program, started about six years ago to more efficiently […]

Even though the SLAC National Accelerator Laboratory is celebrating its 50th anniversary today, we’re guessing that what goes on at SLAC is probably a mystery to most local reasons. In addition to our conversation earlier this week with Dr. Sidney Drell, one of SLAC’s founding scientists, we asked Media Relations Manager Andrew Freeberg to unearth […]

Editor’s note: This weekend the SLAC National Accelerator Laboratory in Menlo Park will celebrate its 50th anniversary. We used the occasion to schedule a visit with Dr. Sidney Drell, the Stanford emeritus professor who has been a part of SLAC for all five of its decades. A theoretical physicist, Drell is equally well known for […]

This has been an exciting summer for particle physicists who have collectively spent the last 40 years hunting for the Higgs boson. Last year, ATLAS and CMS, the two largest experiments analyzing collisions produced by the Large Hadron Collider, observed tantalizing hints of this elusive particle. On July 4th, the two collaborations unveiled their latest […]

Researchers at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory in Menlo Park have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles’ surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important […]
