BICEP2 CORROBORATION BY BICEP1 AND KECK ARRAY

Here is a concise description of the bicep2 team’s position on various controversies:

We put our own results through even more scrutiny than I’ve seen from others so far. There were a few things that made us think we had actually detected the inflationary smoking gun that we’d been looking for. The first is that we accumulated enough data that we could put a number on the statistical significance of our result, which showed that it’s not just a statistical fluctuation. This is a real signal. The second thing was to convince ourselves that the signal is not an artifact of the instrument itself. We spent a lot of time thinking of every crazy idea we could about how the telescope might make a fake signal. One by one, though, we eliminated them all. And then to make ourselves even more confident, we compared the data from BICEP2 with a second telescope called the Keck Array and then with a third telescope called BICEP1. That comparison really drove the point home that this is something that’s really on the sky. Finally, we made sure that it’s not something between us and the beginning of the universe that’s just getting in the way. We did that by analyzing the best information that we have about the dust, synchrotron light and other signals within the galaxy and comparing it to what we saw.

Let’s zero in on the crux: …. we compared the data from BICEP2 with a second telescope called the Keck Array and then with a third telescope called BICEP1.

This is the proof being offered that bicep2 results are not artifactual. So let’s examine the corroborations.

BICEP2 CORROBORATION BY KECK ARRAY:

It sounds most impressive, but Keck Array will corroborate bicep2 any day of the week with a y in it. That is because bicep2 and Keck Array use the same (crappy) imaging technique. The same is true for bicep2 and bicep3.

So Keck Array or bicep3 corroborating bicep2 is like a goodfella giving alibi to a wiseguy who has just bumped off somebody.

BICEP2 CORROBORATION BY BICEP1:

Now this is interesting. Bicep1 uses a different imaging technique than Bicep2. In fact, bicep1 became bicep2 simply by replacing the imaging plane assembly. So this corroboration can be most powerful.

bicep1, bicep2, bicep3, keck array, telescope discovery, keck foundation, kavli foundation, nsf, john kovac harvard, b-mode polarization, e-mode polarization

bicep1, bicep2, bicep3, keck array, telescope discovery, keck foundation, kavli foundation, nsf, john kovac harvard, b-mode polarization, e-mode polarization

The corroboration is shown in the above figure. I have explained here that rather than being a corroboration, it is a clear picture of how bicep2 takes the sky radiation as “the seed” and modifies it to provide an entire gridwork of its own. The polarizations shown here are not actual sky polarizations, but an artifactual rendition of same. B-mode polarization here does not indicate a B-mode polarization in the sky.

So now you can see why the imprint of the inflation era is so starky geometric like a turtle shell pattern and so tightly woven like a rattan hat and so “aligned” with our little RA-dec coordinate system in this little corner of the universe!!

Alles klar?
