So many questions! If I understand correctly, BICEP-3 will observe more channels with greater sensitivity over a larger area, and part of that area is intended to obtain a strong galactic dust signal to aid subsequent analysis of darker areas. Do I have that right? - Will BICEP-3 observations include the same sky patch as BICEP-2? - Is BICEP-3 working as well as hoped? Reliable? Good data? On schedule? - Has the galactic dust model been refined enough to not limit BICEP-3 analysis? - How soon are initial BICEP-3 results expected to be published? - How much BICEP-3 work is independent of the next Keck Array upgrade? About that last question: I'm mainly wondering if BICEP-3 work is being optimized primarily toward the next Keck Array, possibly limiting it's own science objectives.

@colinbischoff4383 3 жыл бұрын

BICEP3 is basically observing the same sky patch as BICEP2 (but a bit of a larger area because of its larger field of view). BICEP3 is working very well, first science results coming out soon. BICEP3 is observing at lower frequency (95 GHz) than BICEP2 (150 GHz), so it should be less affected by Galactic dust. Our understanding of the dust in this patch of sky has been improving with Keck Array data -- it's an incremental process at this point. As of 2020, BICEP3 is operating alongside the BICEP Array, which is a replacement / upgrade of Keck Array.

Somewhat Snakes Should not make much of a difference. Its better to ignore smudges and clean the lenses as little as possible. You'd be surprised how dirty a lens or mirror can get before the image starts to suffer. As an amateur astronomer I only clean my telescope every few years when it's finally caked in dust and the image starts to degrade. Otherwise it's best not to touch, as every time you clean you cause wear and scratches to the coatings and the glass/mirror no matter how careful you try to be.

@BentConrod 6 жыл бұрын

sup no br 🤔 Hmmmm... I'll have a crack at replying.. Scientific instruments designed specifically for tasks such as Background Imaging of Cosmic Extragalactic Polarisation simply don't produce the same results you're familiar with from conventional astronomical telescopes? 2:49 The crazy cold South Pole environment makes it easier to get the telescope's antenna temperature down to 4K, helping to minimise antenna noise, which masks the extremely weak cosmic microwave background being captured. Also, there wouldn't be another location on the globe with lower man made RF polution.

In a way, Aluminum _is_ the proper British way to say it, and neither spelling can be called wrong.
