  Saul Perlmutter Wins E. O. Lawrence Award in Physics
Perlmutter is Berkeley Lab's 25th recipient of the prestigious award, which includes a gold medal and $25,000.
Many of Perlmutter's subsequent accomplishments, notably his leading role in the discovery of the universe's accelerating expansion, owe much to the practical methods he and his colleagues devised for using supernovae as "standard candles" to measure the cosmic expansion rate.
The group in which Perlmutter did his graduate work, headed by Berkeley Lab and UCB physicist Richard Muller, was constructing a robotic telescope to look for relatively nearby Type II "core collapse" supernovae, whose brightness, it was thought, could be calculated from the velocity of their expanding shells.

Saul Perlmutter, Ph.D. Since the 1930s, scientists have known that galaxies are all moving away from one another, and there has been a concerted effort to study the rate of this expansion.
Prior to Perlmutter’s efforts, almost all astronomers expected that the expansion of the universe was slowing, due to the gravitational attraction of galaxies and other matter.
Perlmutter’s estimates of the cosmological constant’s magnitude are consistent with Lange’s observations of a flat universe.

Perlmutter, a senior scientist at the EO Lawrence Berkley National Laboratory whose measurements of the accelerating universe were Science Magazine's 1998 "Breakthrough of the Year," will use an empirical approach to answer the philosophical question about the continuity of the universe.
Perlmutter says light from distant exploding stars (supernovae) mark a path across space and time, which give clues about the universe's rate of expansion and its fate.
Perlmutter will address theories that predict permanence of the universe and unending expansion, as well as the possibility of a mysterious dark energy that may pervade the universe.

Saul Perlmutter, a senior scientist at Berkeley lab and head of the Supernova Cosmology Project, has won this year's E.O. Lawrence Award in physics for his unexpected discovery that the expansion of the universe is speeding up rather than slowing down.
Perlmutter, who got his doctorate at UC Berkeley in 1986, started working in 1988 on what later was called the Supernova Cosmology Project.
Perlmutter says new space telescope, the Supernovae/ Acceleration Probe, has been proposed to study supernovae over a greater range of distances and to get incredibly accurate measurements of thousands of supernovae.

At this point, said Gerson Goldhaber, a gray-beard particle physicist on the Perlmutter team, the technique looked impressive enough that it was adopted by some of the same astronomers who had been vocal critics earlier, such as supernova expert Robert Kirshner of the rival Schmidt group.
While Perlmutter uses high-brow names from the classics for his explosions, Kirshner mischievously noted that the rival team led by Brian Schmidt of Australia's Mount Stromlo and Siding Spring Observatories, had gone the other way with its recent claim to have detected the most distant supernova yet -Dudley Do-Right.
Perlmutter's ambitious "to-do" list includes the establishment of a supernova "factory," an automated telescope scan that will churn out specimens as if on an assembly line, by the hundreds.

 Berkeley Lab Currents -- October 4, 2002
Perlmutter will be cited at the awards ceremony in Washington D.C. on Oct. 28 “for his leading contributions to an unexpected discovery of extraordinary importance: the determination, through the careful study of distant supernovae, that the expansion of the universe is speeding up rather than slowing down.”
Perlmutter’s subsequent accomplishments owe much to the practical methods he and his colleagues devised for using supernovae as “standard candles” to measure the cosmic expansion rate.
Perlmutter and Carl Pennypacker were postdocs in the group headed by Berkeley Lab and UCB physicist Richard Muller when they came up with the idea of using newly identified Type Ia supernovae to measure cosmic expansion.

Perlmutter was part of a team that had earlier discovered the mysterious expanding force by looking at other distant supernovae.
And instead of confirming their theory that the universe is going to expand for a while, then fall back on itself in a "big crunch," they found that in fact something is causing it to accelerate even more.
Perlmutter said his team spent 10 years trying to come up with ways to look at supernovae, which they knew must exist.

 Berkeley Lab: Did You Ever Wonder?
Berkeley Lab scientists led the way to that surprising discovery, and they are leading the effort to determine the nature of the "dark energy" that is stretching space-time itself.
By then the astrophysical bug had bitten him; one possibility that fascinated him was using robotic telescopes to capture fleeting cosmic events "on the fly" -- events such as relatively nearby exploding stars, called supernovae.
Perlmutter and his colleagues soon devised ways to guarantee that ever more distant supernovae could be found; with their new search technique, a few nights on the world's best telescopes dependably resulted in many new supernova discoveries.

 Einstein's "Mistake" is Revived
We could have a closed Universe that continues to expand, pushed on by the mysterious repulsive energy, explains Saul Perlmutter, of the Lawrence Berkeley National Laboratory in California.
To constrain the value of w and thus discriminate among dark energy models, Perlmutter and his colleagues used recent data of three types: measurements of the small variations in the cosmic microwave background; the density of galaxies over large distances; and the expansion speed versus distance relations gained from observing distant supernovae.
Perlmutter stresses that the research is still in "an early stage"--he expects to discriminate more convincingly among models in the coming years, as the many long-term observing projects currently underway report more data.

Astrophysicist Saul Perlmutter, the senior scientist at the E.O. Lawrence Berkeley National Laboratory and the Center for Particle Astrophysics at UC Berkeley, crossed the Bay last Thursday to expand our universe.
Until then, recent astrophysical debate and uncertainty had centered around the question of whether or not the gravitational pull of the universe's mass would be sufficient to reverse its expansion, leading to collapse, or whether the universe would go on expanding forever, but more slowly over time.
A jaw-dropping 65 percent of the energy in the universe needed to account for the universe's accelerating expansion is missing, Perlmutter said.
