TL;DR: In this paper, the physical state and energy balance of cool matter in space were measured in the infrared wavelength domain, enabling the detailed study of the processes that govern the cooling process.

TL;DR: The SAFARI instrument as discussed by the authors is a far-infrared imaging Fourier transform spectrometer for JAXA's SPICA mission, which provides sky background-limited, Nyquist-sampled spectroscopic imaging of a 2' × 2' field-of-view over 34-210 μm.

TL;DR: In this article, the authors report on the TES pixel designs that are being optimized to meet these proposed LPA and SPA configurations, and describe details of how important TES parameters are chosen to meet the specific mission criteria such as energy resolution, count-rate and quantum efficiency.

TL;DR: In this article, the authors demonstrate the simultaneous locking of up to 51 BBFB loops and demonstrate that the in-band read-out noise of the loops reached the 10πA/πAµ/ϵµ level required for the European X-ray mission-under-study Athena and far-IR bolometers for the Japanese mission SPICA.

TL;DR: In this article, the authors developed ultra-low-noise transition edge sensors (TESs) based on a superconducting Ti/Au bilayer on a suspended SiN island with SiN legs for SAFARI.
