On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe

R. Aurvik, M. Galloway, E. Gjerløw +107

We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…

A Simulation Framework for the LiteBIRD Instruments

M. Tomasi, L. Pagano, A. Anand +111

LiteBIRD, the Lite (Light) satellite for the study of -mode polarization and Inflation from cosmic background Radiation Detection, is a space mission focused on primordial cosmo…

Multi-dimensional optimisation of the scanning strategy for the LiteBIRD space mission

Y. Takase, L. Vacher, H. Ishino +105

Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial -mode power spectrum of the Cosmic Microwave Background (CMB). Since this pro…

Monitoring TES Loop Gain in Frequency Multiplexed Readout

T. de Haan, T. Adkins, M. Hazumi +5

We present a method for precise monitoring of the loop gain of transition edge sensors (TES) under electrothermal feedback. The measurement is implemented on the ICE DfMux electron…

Fabrication of a 64-Pixel TES Microcalorimeter Array with Iron Absorbers Uniquely Designed for 14.4-keV Solar Axion Search

Yuta Yagi, Tasuku Hayashi, Keita Tanaka +7

If a hypothetical elementary particle called an axion exists, to solve the strong CP problem, a 57Fe nucleus in the solar core could emit a 14.4-keV monochromatic axion through the…

Development of epoxy-based millimeter absorber with expanded polystyrenes and carbon black

Yuki Inoue, Masaya Hasegawa, Masashi Hazumi +2

We recently developed and characterized an absorber for millimeter wavelengths. To absorb the millimeter wave efficiently, we need to develop the low reflection and high absorption…
