Keys to our lab at HÍ

We received keys to our lab at the University of Iceland on this day! The above picture shows a photo taken on 19 Jan 2023 (above) and on take today. Next step: fill space with equipment.

Nadia submits her first lead author paper to the arXiv!

Nadia Dachlythra submitted her first paper to the arXiv today! The paper describes time-domain simulations of planet beam mapping for the Simons Observatory Small Aperture Telescope (SAT)! The work summarized in this paper helps us prepare for the extensive beam calibration work which will begin shortly after the telescopes are operational. For more info, see: https://arxiv.org/abs/2304.08995

Nadia and Alexandre go to Japan

In November 2022, Nadia and Alexandre went to Tokyo as part of the CMB-INFLATE research network. Nadia was there for two weeks and Alexandre for a full month. They were hosted by Tomotake Matsumara’s CMB research group at IPMU in Kashiwa. While there, Nadia worked with one of the post-docs on developping ideas about beam chromaticity, and Alexandre did simulations for the LiteBIRD HWP.

Alexandre and Nadia experience japanese high technology.

Half-wave plante non-idealities and realistic beams

We study systematic effects from half-wave plates (HWPs) for CMB experiments using full-sky time-domain beam convolution simulations. We investigate how different HWP configurations optimized for dichroic detectors centred at 95 and 150 GHz impact the reconstruction of primordial B-mode polarization.

Lightweight metameterial absorbers

Our groups receives funding from the Swedish National Space Agency to develop novel metamaterial absorbers for future satellite missions studying the cosmic microwave background. This work will build on a great idea developed by our colleagues in the US (see link to paper below). In this work, we will design and print complex three-dimensional structures that absorb mm-wavelength radiation and test those using a holographic reflectometry system that is currently being developed here at SU.
