TL;DR: AKARI as discussed by the authors, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year, and has a 68.5 cm cooled telescope, together with two focal-plane instruments, which survey the sky in six wavelength bands from the mid- to far-infrared.

TL;DR: In this article, a superconducting transition-edge sensor (TES) was developed for future Japanese X-ray astronomy missions (e.g. NeXT mission) and the performance of the single pixel TES calorimeter was presented.

TL;DR: In this article, an array of microabsorbers with a "mushroom-shaped" microstructure for a precision X-ray microdetector, the so-called Xray microcalorimeter, was successfully fabricated by Sn electrodeposition in combination with a photolithographic technique.

TL;DR: In this article, a transition edge sensor (TES) was used as a temperature sensor to improve the energy resolution of an X-ray microcalorimeter, which has an energy resolution almost comparable to that of conventional wavelength-dispersive spectrometers.

TL;DR: In this paper, a Ti/Au TES microcalorimeter array for future Japanese X-ray astronomy missions was developed, which achieved an energy resolution of 2.5 eV at 6 keV with a very fast time constant (μs ).
