Minutes ago, the BICEP2 Collaboration tweeted that it has made several new papers available via bicepkeck.org. No Planck is involved here.
Keck Array (BICEP2.5) telescope.
These papers are one about the instrumental systematics of BICEP2 (the systematic error is 10 times smaller than their statistical uncertainty, the B-modes are discovered at more than 5 sigma), a combination of BICEP2 and Keck Array (it discovers B-modes at more than 6 sigma, noise uncertainty dropped 2.3 times), optical performance (of both experiments), and a joint paper of BICEP2, Keck Array, and SPIDER (about antennas' bandwidth and sensitivities).
The BICEP2+Keck Array Collaboration seems to be the leader in the sensitivity needed to detect the gravitational waves. All the signals become stronger, as expected, but these new papers largely avoid the discussion how to model the dust and how to distinguish dust from the primordial gravitational waves that could have been produced during cosmic inflation.
All these BICEP2+Keck Array papers were running at 150 GHz. Later this year, we may already see some results of BICEP3 at 95 GHz and Keck Array at 220 GHz which could bring rather new information.
