TL;DR: In this paper, a low power, low noise silicon p-channel MOSFET working at 1.8K was successfully developed for the capacitive transimpedance amplifiers (CTIA) for the Japanese infrared astronomical satellite, ASTRO-F.
Journal ArticleDOI
A New Empirical Method for Estimating the Far-Infrared Flux of Galaxies
TL;DR: In this article, the spectral energy distribution (SED) at wavelengths lambda shorter than 100 microns was derived from the IRAS data, and a new empirical method was proposed to estimate the total far-infrared flux of galaxies from the SED.
