Luke Jew

Research Associate

I am a post doctoral research associate working on the C-Band All-Sky Survey (C-BASS). The C-BASS project is mapping the sky at a centre frequency of 5 GHz and with a resolution of just under 1 degree. The C-BASS maps will help better remove polarised foregrounds from CMB maps.

My research interests focus on reducing systematic errors in all-sky radio maps and then using those maps to determine the properties of the diffuse Galactic emission between 1-100 GHz.
Improved maps of the radio sky and a deeper understanding of the diffuse Galactic emission are vital in the current search for primordial CMB B-modes.

I regularly give public talks on a range of astronomical topics, see my outreach page for some links.

The C-BASS webpages have more information on my research

I regularly give talks to the general public and school groups on a range of cosmology related topics, some YouTube videos can be found here.

I have a page on the Oxford Sparks platform where you can listen to my podcast on baking with microwaves, which can be found here.

A couple of videos of my talks can be found on the Oxford podcasts pages here.

I also helped BBC Newsnight make a video explaining the 2014 BICEP 2 detection of primordial CMB B-modes, which was later shown to be mismodelled thermal emission from interstellar dust. The video can be found here.
