Headlines around the world accompanied the announcement in March 2014 by the BICEP2 team that a specific swirly pattern of cosmic microwave background polarization called the B-mode was discovered on large angular scales. After evaluating and rejecting various systematic effects and Milky Way foreground emissions as the cause, the team, including Professor Barth Netterfield and graduate student…

Planck: Gravitational Waves Remain Elusive
Despite earlier reports of a possible detection, a joint analysis of data from ESA’s Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves. CITA scientists Dick Bond and Peter Martin are co-authors on this new study.

PLANCK reveals the Universe’s First Light
The best map ever made of the most ancient light in the universe — the remnant radiation left over from the Big Bang some 13 billion years ago — clarifies our understanding of the universe. The highly detailed image of the universe — produced by the European Space Agency’s Planck Space Telescope and the Planck collaboration of international scientists including a team from U of T —…
PLANCK ALERT: The Veils Come Off March 21st
The first cosmology data release from the Planck mission will take place March 21, 2013 in Paris, at 10 AM CET (4 AM EST).
The Planck results presented will include the world’s highest resolution all-sky map showing the detailed patterns in the remnant radiation left over from the Big Bang some 13 billion years ago. To create the map, the Planck scientists removed the bright foreground…
