LiteBIRD Newsflash

Posted in The Universe and Stuff with tags , , , , on May 23, 2019 by telescoper

Just a quick post to pass on the news that the space mission LiteBIRD has been selected as the next major mission by the Japanese Space Agency JAXA and  Institute for Space and Astronautical Science (ISAS).

LiteBIRD (which stands for `Lite (Light) satellite for the studies of B-mode polarization and Inflation from cosmic background Radiation Detection’) is a planned space observatory that aims to detect the footprint of the primordial gravitational waves on the cosmic microwave background (CMB) in a form of a B-mode polarization pattern. This is the signal that BICEP2 claimed to have detected five years ago to much excitement, but was later shown to be a caused by galactic dust.

It’s great news for a lot of CMB people all round the world that this mission has been selected – include some old friends from Cardiff University. Congratulations to all of them!

I’m not sure when the launch date will be, but the mission will last three years and will be at Earth-Sun Lagrange point known as L2.It will be a very difficult task to extract the B-mode signal from foregrounds and instrumental artifacts so although there’s joy that it has been selected, the real work starts now!


Irish Quantum Foundations and Other Matters

So here I am then, at Irish Quantum Foundations (IQF) 2019 which is being held in the Hamilton Building (shown above), and hosted by the School of Mathematics of the College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, which is sometimes known as Trinity College, Dublin for short.

I got here a bit later than I originally planned as some last-minute things came up this morning to do with next week’s events. I’ll have to skip tomorrow morning too, for similar reasons. When I did get going this morning I had to stand all the way from Maynooth to Connolly because the train was packed. At least it was reasonably on time though.

Anyway, the schedule of IQF 2019 is rather varied and I’m looking forward to the parts of it that I can attend.

Among the things I have been dealing with to do with next week are  submitting the final version of pedagogical piece about the Eclipse Expeditions of 2019 which should be published very soon in Contemporary Physics (at least in the online version) and writing a short piece for RTÉ Brainstorm (which will appear on Monday 27th May), and sorting out an appearance on Newstalk Radio next week. How I’ll get time to finish my exam marking in the middle of all this I don’t know!
