UCSB: POLARBEAR Detects Curls in the Universe's Oldest Light

POLARBEAR Detects Curls in the Universe's Oldest Light
University of California, San Diego | 2014 Oct 20

Early success in the experiment’s first observing season
Cosmologists have made the most sensitive and precise measurements yet of the polarization of the cosmic microwave background.

The report, published October 20 in the Astrophysical Journal, marks an early success for POLARBEAR, a collaboration of more than 70 scientists using a telescope high in Chile’s Atacama desert designed to capture the universe’s oldest light.

“It’s a really important milestone,” said Kam Arnold, the corresponding author of the report who has been working on the instrument for a decade. “We’re in a new regime of more powerful, precision cosmology.” Arnold is a research scientist at UC San Diego’s Center for Astrophysics and Space Sciences and part of the cosmology group led by physics professor Brian Keating.

POLARBEAR measures remnant radiation from the Big Bang, which has cooled and stretched with the expansion of the universe to microwave lengths. This cosmic microwave background, the CMB, acts as an enormous backlight, illuminating the large-scale structure of the universe and carrying an imprint of cosmic history. ...

As soon as this broke, a snarky picture began going around the 'net courtesy of Robert McNees and Katie Mack. Think these curls will stick harder than BICEP's?

Just call me "geck" because "zilla" is like a last name.
